The paper is devoted to the problems of operation of wells equipped with units of submersible electric centrifugal pumps under conditions of the action of factors that significantly complicate and extremely negatively affect the operation of a submersible unit. Wells failures are analyzed taking into account various operating conditions and the main reasons were identified: wear of pumps working parts, failure of the cable line and failure of the submersible electric motor. In most wells, pump wear is associated with an increased content of mechanical impurities in the product produced from the wells. The main factors of complications are considered, such as a decrease in temperature in the wellbore and formation of a well, intense gas manifestation, pressure decrease in the near well-bottom formation zone, which cause changes in the ratio of oil and water volumes and contribute to salt deposition, corrosion and the formation of asphalt-resin-paraffin deposits. The component composition of asphalt-resin-paraffin compounds is considered. The most widely used chemical methods for preventing complications (corrosion, salt and paraffin deposition, etc.) are considered. A new technological scheme for supplying a reagent has been proposed, which will prevent the deposition of salts and paraffin, and is also capable of performing its functions in the cold season.

 

Keywords: electric centrifugal pumps; scale deposits; asphalt-resin-paraffin deposits; equipment failure.

The technology of water purification from oil products by means of open porous granules based on mineral sedimentary opale-cristobalite rock endowed with high porosity owing to the presence of large amount of nano-measured pores, which allows for creating on granules surface a shell of water held in the pores during the filtering process is suggested. The water shell provides an effective and non-disrupting regeneration of granules by means of backwashing in fluidized state, which is done in the mode enabling the quality granules cleaning without destruction thereof.

For primary entrapping and retention of crude oil drops on the surface of granules, in composition thereof some particles of a non-porous material with high adhesion to the oil products are introduced. These particles create oleophilic areas on the surface of granules where only small oil droplets are retained. During the filtering process the larger drops are adjoining to them due to the coalescence, creating larger drops and further interconnected oil bundles "clamped" between the granules. This leads to the formation of a multi-phase structure effectively entrapping the tiniest oil drops. The effectiveness of the suggested technology was confirmed by the data obtained from the pilot researches as well as by implemented projects at industrial facilities in Russia and abroad.

 

Keywords: emulsion; water purification; filtering; emulsions separation; filtering materials; crude oil; oil products; porous carrier.

The article presents the technology of reagent treatment of highly mineralized oil-containing waste water to prevent corrosion processes on the inner surface of inter-field pipelines when implementing the technology of steam-thermal impact on the reservoir in the conditions of high-viscosity oil production. Optimal dosages of lime and soda have been selected to reduce the concentration of petroleum products, mechanical impurities, hardness salts, total iron and silicon in purified water to regulatory requirements. Reducing the concentration of hardness salts in treated water prevents the formation of precipitation during its transportation through inter-field water pipelines and reduces the likelihood of corrosion processes, in addition, it helps to reduce the consumption of salt deposition inhibitors.

Filtration constants, sediment properties, and the value of its resistivity during filtration have been experimentally determined, which at the design stage will make it possible to correctly calculate and select the appropriate equipment.

The technology of low-temperature pyrolysis is proposed for utilization of oil sludge generated during the purification of raw water, which allows not only to neutralize oil sludge, but also to additionally obtain liquid (pyrolysis) fuel and pyrolysis gas, which can be used in oil preparation technology.

 

Keywords: reservoir water; lime milk; oil products; suspended solids; corrosion; filtering; filtering constants; low temperature pyrolysis.

Water injection as a method of influencing oil reservoirs has been used in our country for over 70 years. Such a long period of its implementation in reservoirs of varying complexity in terms of geological structure and in a wide range of filtration-capacitive characteristics made it possible to formulate not only the positive characteristics of the method, but also to determine complicating factors and negative processes occurring in the reservoir during a prolonged water injection. The introduction into development of oil reservoirs, the properties of which significantly differ from the favorable conditions for the implementation of water flooding, the lack of incentives for widespread use of enhanced oil recovery methods, led to the development of new modifications of the water flooding method, technologies that allow using negative or complicating factors as positive ones. In other words, the specialists directed their knowledge and experience to the creation of technologies based on the use of water of different quality and different salinity, increasing the oil recovery factor. Such technologies expand the possibilities of controlling the water flooding process and lead to an increase in the efficiency of its application in difficult geological and physical conditions.

 

Keywords: oil field development management; non-stationary water flooding; cyclic water flooding; quality of the injected water; mineralization of the injected water.

The paper is devoted to the two aspects of the objective function formulation for automated history matching of geological-hydrodynamic hydrocarbon reservoir models, which are the mismatch expression and the component composition of the objective function. Numerical modeling is used in the development of oil and gas fields to improve the efficiency of hydrocarbon reserves recovery. Before using the model for forecasting it is matched to the production history data, so that the model will reproduce the historically observed parameters of the wells operation. The optimization algorithm and the objective function are the integral parts of the automated history matching. The objective function expresses the deviation of the calculated well performance indicators from the actual ones and allows the optimizer to find the inverse problems solutions. The purpose of this work is to study the influence of the mismatch expression and the component composition of the objective function on history matching efficiency. The novelty of the research lies in the study of the influence of three types of mismatch expressions of the objective function on history matching, both analytically and confirming by multiple computational experiments. The results of this study helped to develop recommendations regarding the mismatch expression and the component composition of the objective function for reservoir model history auto-matching.

 

Keywords: mismatch expression; mismatch; component composition; objective function; automated history matching; automated history matching of a model; optimization algorithms; history matching quality; reservoir geological-hydrodynamic simulation; oil field; numerical model.

The paper considers the problem of taking into account the stress-strain state of pipes metal and pipe fittings when assessing the danger of operational and technological defects. It is shown that the use of modern means of in-line flaw detection allows, with sufficient accuracy for engineering calculations, evaluation of changes of pipelines geometric shape and, as a result, the effect of these changes on the stress-strain state of pipes and fittings metal. It is substantiated that the currently adopted classification of hazardous areas by bending radius does not provide equal safety margins for pipelines of different diameters. A new approach to ranking the hazard of elastic plastic bends is proposed, and the results of this approach testing at three sections of main gas pipelines are presented.

The purpose of the monitoring systems is to implement automated monitoring and analysis of the operational parameters of turbocompressor equipment, allowing the management and operational personnel of operating organizations to have objective information about the efficiency of the turbocompressor equipment and its technical state.

At present, automated monitoring systems are designed to determine the current technical state or assess the quality of repairs and ensure the safety of operation within the assigned operational life-time. When solving the problem of extending the service life of equipment, beyond the design life of its operational life-time, including the most loaded parts and assemblies, it is necessary to perform a set of works on diagnostics, non-destructive and destructive testing, calculation and experimental work on strength, taking into account the degradation of material properties in order to determine the ultimate resource and timely replacement of such parts and assemblies in a planned manner. Carrying out such extended surveys significantly increases the cost of the industrial safety examination procedure and does not provide a full guarantee of safe operation beyond the assigned resource.

Therefore, one of the main functions of modern automated monitoring systems being created within the framework of the industrial safety examination procedure should be the process of monitoring changes in the technical state of units that have worked out their limiting operational life-time, and parts and assemblies the operational life-time of which is less than the operational life-time of the equipment as a whole.

The paper is devoted to the assessment of the technical state and residual resource of the linear part of the main pipelines and compressor stations technological pipeline. Approaches to assessing the hazard of fracture-like defects based on the criteria of linear fracture mechanics are considered. An approach to assessing the influence of elastic-plastic deformation along the crack front on the degree of defect hazard is formulated.

It is shown that taking into account the inhomogeneity of pipelines mechanical characteristics of steels when assessing their technical state and residual operational life-time can be carried out by using Irwin's corrections, the formula of which is formulated taking into account the correlation between the steel yield strength and hardness values. The results of mechanical tests of a pipe segment made of steel of strength class K65 are presented. The results of the experiment, which showed the presence of a significant inhomogeneity of the mechanical characteristics along the pipe wall thickness, are analyzed.

 

Keywords: main gas pipeline; technical diagnostics; stress-strain state; limit state criterion; fracture mechanics.

Over the past ten years, the authors have repeatedly in their articles and reports at seminars and conferences dedicated to the diagnosing equipment and pipelines of compressor stations (CS), addressed the problem of combining protection from industrial noise with ensuring CS reliability. Protection against industrial noise at a compressor station is partially solved by the use of noise-insulating coatings for technological pipelines. These coatings are usually disposable and are designed to last for decades. As a result, the technical state of pipelines: structural, installation and operational defects, the development of corrosion processes due to the penetration of moisture between the pipe and the coating has not been monitored for decades. According to the authors, there is currently no reliable justification for both the use of soundproofing coatings and the choice of the type and design of soundproofing. Nevertheless, until now, in the projects of the compressor station pipelines, it is proposed to use noise insulation for almost all objects, even for those ones where it is a priori ineffective. An example of such an unreasonable use of noise insulation is considered in this paper.

One of the key directions of energy conservation in the gas industry is energy efficiency improvement of natural gas compression process. As a criterion for compression efficiency evaluation, the specific consumption of fuel gas is used: per unit of total polytropic work of compression ETPWC and per unit of volume of compressed natural gas ETG. The paper presents the calculated ratios for these indicators. Their factorial analysis was carried out to assess the influence of the operating modes parameters of gas-compressor units (GCU) on the energy efficiency of the compression process. Based on the results of the factor analysis, a methodological approach to the systematization and classification of energy-saving measures at compressor stations equipped with gas turbine GCUs is proposed.

 

Keywords: compressor station; gas compressor unit; fuel gas; energy saving; energy efficiency; energy efficiency indicators; energy intensity.
