Title: Method for development of multi-layer inhomogeneous oil deposit
Inventor: ISHKAEV RAUVEL KALIMULLOVICH
IPC: E21B43/20
Filed: 1995-06-08
Granted: 1996-05-27
Abstract: FIELD: oil production, development of multilayer inhomogeneous oil deposit. SUBSTANCE: oil is extracted through producing wells and working agent is injected through injection wells until 0.60 - 0.75 stratum pressure of initial one is achieved. Producing wells are brought out of operation at comminuted object in zones with 0.60 - 0.70 stratum pressure of initial one. Well development is continued in the mode with stratum pressure increased up to 0.85 - 0.90 of initial one. By-product Devonian water of 1.11 - 1.14 gram per cubic centimeter density is pumped in as a working agent. Nonoperated wells are brought into operation with stratum pressure nearby well achieved 0.70 - 0.75 value of initial stratum pressure. Additional wells are drilled over all deposit depth. When the wells passing through productive oil stratum they are operated as producing. With wells passed to water underlaying bed missing oil bed, they are operated as water intake wells, with stratum underlaying DEvonian water extracted through the wells and pumped in injection wells as working agent. EFFECT: high productivity. 1 tbl
