METHOD OF EXPLOITATION OF OIL POOL ( VERSIONS )

摘要

exploitation of hydrocarbon deposits of complex geological structure with inhomogeneous and low- penetrable collectors. SUBSTANCE: according to proposed method dependence of gas factor on value of depression on pool with seam pressure below saturation pressure is found in production wells over developed section of pool. When time constancy of gas factor corresponding to initial seam pressure is achieved poll is exploited under condition of depletion with keeping of depression on pool ensuring this constancy in production wells. If it is impossible to create depression on poll ensuring keeping of gas factor at level of initial seam pressure then pool is exploited under water-pressure condition to obtain flooding of products in production wells. Later pool is transferred to exploitation under depletion condition. EFFECT: formation of saturation pressure of condition of foam flow of oil and gas mixture that provides for maximum oil yield capacity. 2 cl, 2 dwg
