e-mail: taf@list.ru

Problems of qualitative cleaning of technological drilling fluid from drill cuttings, heavy metals, toxic components of drilling fluids and petroleum hydrocarbons in marine environment such as on an offshore drilling platform, drilling ship and underwater drilling complex are analyzed. It is shown that at present there exists the problem of not only with qualitative cleaning of technological drilling fluid from fine drill cuttings, heavy metals, toxic components of drilling fluids and petroleum hydrocarbons but also with drill cuttings dehydration before its transportation to the shore.

It is proved that the developed method of integrated nonchemical cleaning of technical drilling fluid and drill cuttings dehydration completely corresponds to the quality-productive capacity-cost-energy consumption-ecological safety criterion that becomes especially important both in conditions of global financial-economic crisis, and limited space on an offshore drilling platform (drilling ship or, moreover, underwater drilling complex).

The results of some comprehensive nonchemical cleaning of circulating water and industrial wastewater as well as sludge dewatering obtained from oil and gas companies and mining industry in Russia and the countries of South-East Asia (Korea, Vietnam, and others) are presented.

It is recommended to use the unit of complex influence on technical drilling fluid at oil and gas companies of the Russian Federation not only in marine (including under the ice – in the Arctic conditions), but also in coastal conditions.

Key words: drilling; offshore platforms; technological drilling fluid; drill cuttings; cleaning of technological drilling fluid; cuttings dehydration; acoustics, nonlinear underwater acoustics.

Use of radon-helium survey allows detecting conductive tectonic fractures being the migration way of not only radioactive elements, but also various gases including hydrogen sulfide. Such processes of migration of radioactive and toxic gases need to be monitored, since entering the atmosphere or ground they can have a serious impact on human health and the environment. Description of tectonic faults researches by means of radon-helium surveys is submitted. The proposed solution of the problem includes their monitoring by installation of special cameras. It is found out that radon concentration above long-developed deposits is much higher than above deposits that were put into development only recently. To protect people and the environment it is recommended to monitor the areas with identified tectonic faults.

The method of determination of geometrical parameters of drill-bit cutting structures of drilling tools is developed on the basis of wear-out mathematical modeling using methods of planning and organization of the experiment. The experiment was conducted with account of the most influential factors that were identified by means of factor analysis methods. The planned and carried out experiment resulted in the development of adequate regression model of wear-out inside the factor space.

The proposed method allows essential simplifying the problem of designing the geometry of drill-bit cutting structures of drilling tools. Due to the possibility of fixing the value of one of the main drilling parameters (weight on the bit, WOB), the recommended cutting-point angle and teeth pitch, ensuring maximum operational efficiency of drill-bit cutting structures in all major types of drilled rocks can be determined with sufficient accuracy.

Application of the method while designing the geometry of drill-bit cutting structures of drilling tools will allow significant reduction of time and cost required for development of some new designs of drilling tools.

Key words: rolling cutter drilling bit; wear-out of drill-bit cutting structures; planning and organization of the experiment; mathematical modeling.

The method of cold extraction of oil with sand is successfully applied at numerous heavy oil fields of Canada, China, Venezuela and other countries. While applying this method there can be reach relatively high recovery factors. It could be obtained at the expense of a formation damage and creation of wormholes, thus leading to a formation permeability increase (mainly in the near hole-bottom zone of a production well). Foamy oil effect also contributes to relatively high efficiency of the method.

Various geo-mechanical models such as critical radius model, model of equivalent damage zone, wormholes growth various models (fractal, corresponding to fluidization rate) that describe the formation damage process during "CHOPS" method application are also reviewed in this paper.

Finally some post-CHOPS methods which are aimed at even more increasing of a field development efficiency, being at the latest stage of its development, are recommended for application.

Key words: CHOPS; formation damage; wormholes; heavy oil; equivalent damage zone; post-CHOPS methods.

Statistical processing of the field data firstly requires proving the fact whether there is some relationship between two or more parameters, and what the degree of influence of each of the factors considered and their combination on the process under study is. It is known that the main parameters characterizing the efficiency of the development of offshore gas- and gas-condensate fields are gas- and gas-condensate recovery factors.

The present article studies a field parameters influence on gas recovery factor and by applying associative analysis defines parameters of the process that decisively influence on gas recovery factor. To study the joint effect of defining parameters on the value of gas recovery factor and to build some approximate dependence of gas recovery factor depending on these parameters it is necessary to apply some systematic approach that is the most effectively realized with the help of the experiment planning theory. The method of application of the experiment planning theory in case of mathematical modeling was used to build the regression equation.

The experiment planning theory served the basis for obtaining interpolation formula required for calculation of gas recovery factor depending on the determination factors as well as for demonstrating the effectiveness of this method.

Key words: gas recovery factor; determining parameters; interpolation; regression equation; field parameters; field’s horizon.

The paper describes technological schemes of use of spring-type flow controllers and low pressure regulators in a formation pressure-maintenance system. Spring-type flow controllers allow reducing nonproductive injection into injection wells as compared to widely used chokes. Low pressure regulators make it possible to eliminate emergency shutdowns and restarts of cluster pumping stations as well as pump repairs due to high pressure in the water supply line and pump inlet. Use of flow controllers and pressure regulators at the facilities of a formation pressure-maintenance system (both individually and in combination) is aimed at enhancing the efficiency of control over water cluster injection into formations.

Key words: formation pressure maintenance; water injection control; flow controller; pressure regulator; efficiency enhancement.

The process of sediment consolidation from the point of view of continuous medium mechanics is studied. To describe the process of sediment consolidation in an oil trap sludge compactor it is proposed to use the energy condition of power balance. It is stated that the energy condition of power balance allows establishing communication between the parameters of the sludge compaction process such as geometric, kinematic and rheological parameters, specific friction force of sludge particles on the wall sludge compactor, sludge specific weight and the hydrodynamic pressure (head) forces. The results of some comparative calculation of a sludge layer pressure in a wedge-shaped area of the sludge tank are presented.
