PROCESS OF DEVELOPMENT OF LITHOLOGICALLY SCREENED OIL- SATURATED LENSES BY TWO WELLS

摘要

FIELD: oil industry. SUBSTANCE: invention refers to processes of development of oil fields in which boundaries insulated, lithologically screened oil-saturated lenses opened by two wells of operation fund are encountered. Process secures formation of current of high-conducting channels along neutral lines and inclusion of oil stocks in rear part of wells in development. Injection and production wells are entrained in development. Channels high-conducting and deeply penetrating into bed are formed. Forcing agent is pumped through injection well and well fluid is recovered from production well. In correspondence with invention filtration flow in bed is analyzed in addition. Directions of main and neutral lines of current between injection and production wells is established. High-conducting channels reaching boundaries of lens are created by hydraulic fracturing of bed. Direction of high-conducting channels in region of injection well is determined by convention with continuation of main line of current from injection well to boundary of lens, to side opposite to production well. Direction of high-conducting channels in region of production well is also established by convention with continuation of main line of current from production well to boundary of lens, to side opposite to injection well. EFFECT: formation of high-conducting channels for inclusion of oil stocks in rear part of wells into development. 1 cl, 1 dwg, 2 tbl
