Abstract

FIELD: oil production. SUBSTANCE: oil discharge increment is forecasted taking into account degree of well productivity decrease at the expense of pollutants. The degree is accounted by dividing into parts the component of productivity fall degree caused by natural growth of water saturation of nearby areas in the process of operation. EFFECT: increased productivity.

Изобретение относится к нефтяной промышленности, в частности к способам обработки призабойных зон (ОПЗ) скважин для интенсификации притока нефти.Известен способ интенсифицирующей приток нефти ОПЗ с предварительным выбором скважин под ОПЗ на основе анализа геолого-промысловой информации, определяющими параметрами которой являются степень падения продуктивности в процессе эксплуатации скважины и соответствующий прогнозный прирост дебита нефти по скважине. С целью повышения эффективности способа за счет увеличения надежности выбора скважин под ОПЗ по предлагаемому способу прирост дебита нефти по скважине прогнозируют с учетом степени падения продуктивности скважины за счет загрязнения ПЗ, рассчитываемой путем вычленения составляющей степени падения продуктивности, обязанной естественному росту водонасыщенности ПЗ в процессе эксплуатации.The invention relates to the oil industry, in particular to methods for processing bottom-hole zones (BHP) of wells for stimulating oil inflow. A method is known for stimulating oil flow BH with preliminary selection of wells under BH based on the analysis of geological and field information, the determining parameters of which are the degree of productivity decline in the operation of the well and the corresponding predicted increase in oil production in the well. In order to increase the efficiency of the method by increasing the reliability of selecting wells for SCR according to the proposed method, an increase in oil production per well is predicted taking into account the degree of decline in well productivity due to contamination of the well, calculated by isolating the component of the degree of productivity decline due to the natural increase in the water saturation of the PP during operation.
