Claims (1)

Способ разработки нефтегазоконденсатной залежи, включающий отбор нефти и газа через добывающие скважины и закачку рабочего агента через нагнетательные скважины с созданием смешанных систем заводнения, отличающийся тем, что периодически в нефтедобывающих скважинах проводят замеры газового фактора добываемой продукции и определяют количество газа, поступающего в скважину из газовой шапки, при увеличении количества газа из газовой шапки увеличивают закачку рабочего агента через нагнетательные скважины, поддерживая компенсацию отбора пластовых флюидов с учетом отбора газа из газовой шапки для пластовых условий, а при уменьшении количества газа из газовой шапки в добывающих скважинах - уменьшают закачку рабочего агента через нагнетательные скважины, барьерное заводнение формируют на участках интенсивного отбора нефти, при этом нагнетательные скважины размещают на границе газовой шапки и нефтяной зоны, формируя барьерное заводнение по периметру внешнего контура газоносности, ведут параллельную разработку газовой шапки и нефтяной зоны при соответствии отборов пластовых флюидов из нефтяной зоны и газа из газовой шапки, эквивалентных для поддержания соответствия пластового давления за барьерным рядом и до него.A method of developing an oil and gas condensate deposit, including the selection of oil and gas through production wells and pumping a working agent through injection wells with the creation of mixed waterflooding systems, characterized in that periodically in the oil producing wells they measure the gas factor of the produced product and determine the amount of gas entering the well from the gas caps, with an increase in the amount of gas from the gas cap, increase the injection of the working agent through injection wells, supporting compensation selection reservoir fluids, taking into account the selection of gas from the gas cap for reservoir conditions, and with a decrease in the amount of gas from the gas cap in production wells, the injection of the working agent through injection wells is reduced, barrier waterflooding is formed in areas of intensive oil extraction, while injection wells are located at the gas boundary caps and the oil zone, forming a barrier waterflood around the perimeter of the outer contour of gas content, are conducting a parallel development of the gas cap and the oil zone in accordance with the selection of plas fluid from the oil zone and gas from the gas cap, equivalent to maintain conformity of reservoir pressure behind and before the barrier row.
