Adaptive technique of the approximate estimation of technical and economic indicators of the development of the object of the exhausted gas condensate deposit

Abstract

The method of evaluation of technical and economic indicators for the development of gas condensate field tested in the branch system of enterprises of PJSC "Ukrgazvydobuvannya" is considered, which is supplemented and simplified for obtaining approximate estimates in the case of annual natural or artificial changes in the gas condensate factor and thermobaric states of the extracted fluid during the operational period of the late stage. Targeted changes in the algorithms of calculations of basic technical and economic indicators, especially for partially exhausted deposits, which have become permanent in operation with compressed compressor stations and fixed pressure on the wells, are used, dry gas is used for returning to the formation or dehumidification of the hinterland. The main factors of influence on the final results of the technical and economic evaluation are determined. Improvement of the technique of an approximate estimation of technical and economic indicators of the development of the gas condensate deposit facility for the possibility of adaptation of calculations at the late stage, which usually involves the operation of the SCS, the use of PPE technologies, the drying of the faces by high-pressure gas, and artificial adjustment of the working pressures of wells. The changes in the results of technical and economical calculations are taken into account when taking into account the parameters of the DKS, PPD, thermobaric intensification for the possibility of use in production and in the educational process.
