The article describes a device of the wireless control of process parameters when using the turbine method of wells drilling. The device allows simultaneous controll of two drilling parameters – bit’s rotation frequency and turbine’s axial play. The quarter-wave acoustic resonator is proposed to be used as a pulse generator. The basic operational principal of the pulse generator is to suppress the noise at the resonance frequency of the resonator chamber thus creating a wave break. The wave pause is proposed to be presented as some information of a binary system (1 – for a signal presence, 0 – no signal), i. e. as some technological information about the number of a turbo-drill shaft revolutions (if you apply this phenomenon to the technical solution in the technology of oil and gas wells drilling). The calculation formula for the resonant frequency of the resonator chamber and the device design measuring rotation frequency a turbo-drill shaft revolutions with a quarter-wave resonator built into the housing of the turbo-drill sub are presented.

 

Key words: turbine drilling; oil and gas wells; acoustic resonator; rotation frequency; turbo-drill; turbine shaft RPM meter; wellhead; axial play of the turbine; swivel.

Modern ultrasonic flow-meters can detect gas flow rate with accuracy of ~0,3 %. However, when re-calculating the gas volumes transmitted in working conditions into the standard cubic meters this accuracy can not be realized, since the re-calculation coefficient includes the compressibility factors ratio, which is defined with a substantially high error. The article deals with the previously proposed direct method of determining the ratio of compressibility factors k, based on the use of the relationship between gas density and dielectric permeability (the Clausius-Mossotti). Implementation of the method is carried out with the help of the technique, measuring the frequency shift of high-quality open millimeter-range resonator. The error of value k determination is in the range of 0,1...0,3 %. The advantage of this method is its efficiency as well as easy processing of the data received.

 

Key words: natural gas; compressibility factor; leading to standard cubic meters; microwave technology; open resonator.

The article reviews frequently used methods for well-candidates selection to be subjected to different geological-technical measures (GTM) presented both in Russian and foreign publications. Comparative analysis of classic methods (such as a detailed well-by-well analysis, regression and PCA method) and non-classic methods (including neural networks, genetic algorithms and fuzzy logic) is performed; advantages and disadvantages of every method are investigated. The advantages of classic methods are possibility of the information detailed analysis, assessment of its quality and accuracy. However, those methods tend to be time-consuming. Virtual methods are highly effective in case of big amounts of input data, though they are sensitive to its quality and require manual configuration. The article also emphasizes, that in spite of numerous publications dedicated to the problem, only rare sources contain results of application of that or other methods for well-candidate selection on real objects. Though the problem considered is important, especially for big fields, universal approach to its solution does not exist at present time.

 

Key words: geological-technical measures (GTM); planning of geological-technical measures (GTM); well-candidates selection; neural networks; treatment effect forecast; oilfield development monitoring.

Servicing and repair of basic technological equipment at the enterprises of the fuel and energy complex of the Russian Federation is a priority objective, the solution of which must take into account the requirements of industrial and environmental safety as well as production efficiency.

Relevant field to update the well-known methods of the main technological equipment maintenance when producing and transporting natural gas is optimization of the technical service system applying the innovative techniques of technical diagnosing of GTU-16PA booster station on the basis of the PS-90GP-2 aviation engine. To develop the above-said technique according to the technical design specifications of JSC "Severneftegazprom" specialists at the booster compression station (BCS) of Yuzhno-Russky field, design engineers of GTU-16PA, possessing the required operation-time base of the whole park of drives, scientific and technical resources as well as parameters of the initial acceptance tests without which the complete technical state analysis is impossible, were involved. The article presents the stages of development and the results of the implementation of the technical diagnostics method of BCS at Yuzhno-Russky oil and gas-condensate field, as well as recommendations on the method application at the objects of fuel and energy complex when going to GPA maintenance by "real state".

 

Key words: technical diagnostics technique; gas-turbine unit – GTU-16PA; maintenance system; main process equipment; production efficiency.

The article, on the basis of the analysis, presents some classification of the most common information systems by types of transportation, including the main functions and fields of their applications as well as the processes occurring in them. The standard model of open systems interaction is considered. The degree of use of each OSI level in the transport information systems is analyzed. The methods of guarantee of data transfer safety at different levels of the standard model of the open system interaction are considered as well Data transfer channels, used in transportation are discussed in detail. Particular attention is paid to the data transfer at the network layer in the multi-service network of the transportation industry (based on NGN concept) with further practical application of Multiprotocol Label Switching technology. Some mathematical model that allows setting a one-criterion optimization problem of data transmission in such network is obtained. Further options of the model development are considered. The basic difference of data transfer channels in information networks for different types of transport is identified.

 

Key words: information systems of transport industry; network safety; the standard model of interaction; multi-service networks.

The paper, in terms of the models of non-stationary heat and mass transfer studies the interaction of thermal and hydrodynamic fields with account of the throttle effect during spatial filtering of a condensate mixture in a permeably non-uniform formation. The algorithm is implemented in the software; the dynamics of the output indicators over a wide variation of adjustable parameters is analyzed. These results complement the well-known data about the formation of temperature fields in a formation at a gassy liquid spatial filtration with account of thermo-hydrodynamic effects and can be used to improve the reliability and accuracy of a well data interpretation.

 

Key words: reservoir heterogeneity; non-isothermality of a process; thermodynamic effects; Joule-Thomson coefficient; convective transfer rate.
