Description

Изобретение относитс  к способам разработки нефтегазовых месторождений. Известен способ разработки нефтегазовых залежей с газовой или газоконденсатной шапкой (природной или искусственной) путем циклического нагнетани  агента (например, газа) в шапку и его отбора из шапки. По предлагаемому способу в газовой (газокопденсатной ) шапке поддерживают среднее за цикл давление на уровне давлени  насыщени  нефти. Это повышает эффективность процесса разработки залежи. Способ реализуют следуюш,им образом. Предварительно создают вод ную оторочку, раздел ющую нефт ную часть залежи и шапку , после чего осуществл ют закачку в шапку газа при одновременной добыче нефти из нефт ной части залежи. Благодар  снижению пластового давлени  ниже давлепи  насыщени  пефти газом в нефт ной части из нефти выдел етс  часть растворенного газа, что приводит к повышению коэффициента вытеогени  нефти водой (оторочки ) при последующей закачке газа. Кроме того, наличие в порах свободного газа повышает упругоемкость системы, создает услови  дл  повышени  эффективности вытеснени  нефти водой за счет циклического характера изменени  давлени . Целесообразно циклы закачек и отборов газа проводить так, чтобы они совпадали с циклами газопотреблени . Предлагаемый способ можно использовать и на нефтегазовых месторождени х с газоконденсатной шапкой. Тогда в перпод отбора газа добывают также и газокондепсат. В случае отсутстви  газовой шапки создают искусственную газовую шапку. Дл  этого в купольную часть нефт ной залежи предварительно закачивают воду и тем самым создают вод ную оторочку. Затем, циклически череду  закачку и отбор газа по заданпому технологическому режиму, получают искусственную газовую шапку. Предмет изобретени  Способ разработки нефтегазовых залежей с газовой или газоконденсатной шапкой (природной или .искусственной) путем циклического нагнетани  агента (например, газа) в шанку и его отбора из шапки, отличающийс  тем, что, с целью повышени  эффектпвностг процесса разработки, в газовой (газоконден сатной) шапке поддерживают среднее за цикл пластовое давление на уровне давлени  насыщени  нефти.The invention relates to methods for developing oil and gas fields. There is a method of developing oil and gas deposits with a gas or gas condensate cap (natural or artificial) by cyclic injection of an agent (for example, gas) into the cap and its removal from the cap. According to the proposed method, the gas pressure (gas condensate) cap is maintained at the level of oil saturation pressure, which is average per cycle. This increases the efficiency of the reservoir development process. The method is implemented in the following way. A water rim is preliminarily created separating the oil part of the reservoir and the cap, after which gas is pumped into the cap while the oil is extracted from the oil part of the reservoir. By reducing the reservoir pressure below the saturation pressure of the gas in the oil portion, part of the dissolved gas is released from the oil, which leads to an increase in the rate of oil production with water (rim) during subsequent gas injection. In addition, the presence of free gas in the pores increases the resilience of the system, creates conditions for increasing the efficiency of oil displacement by water due to the cyclical nature of the pressure change. It is advisable to carry out the cycles of gas injection and gas extraction in such a way that they coincide with the gas consumption cycles. The proposed method can also be used in oil and gas fields with a gas condensate cap. Then, gas condensate is also produced in the sub undergill. In the absence of a gas cap create an artificial gas cap. To do this, water is pre-pumped into the domed part of the oil reservoir and thereby create a water rim. Then, cyclically a series of gas injection and gas extraction according to a given technological mode, an artificial gas cap is obtained. Subject of the invention. A method for developing oil and gas deposits with a gas or gas condensate cap (natural or artificial) by cyclically injecting an agent (e.g. gas) into a shank and removing it from the cap, characterized in saturation cap is maintained at the pressure average at the cycle level at the level of oil saturation pressure.
