PROCESS OF DEVELOPMENT OF OIL FIELD AT LATE STAGE OF ITS OPERATION

摘要

oil production, development of multipool oil deposit with irregular degree of collector properties of enclosing rock at late stage of its exploitation. SUBSTANCE: area plugging is conducted by way of pumping of insulation material in the form of clay-cement suspension into pool through all injection wells of field. Plugging is carried out where water content of production wells reaches more than 50% and injection wells have acceptance capacity over 400 cu m/day. In this case pumping is conducted under pressure corresponding pressure of injection line. After it all wells in radius of potential reaction are closed for 2-3 days for consolidation of suspension in pool. EFFECT: raised degree of recovery of residual oil from deposits with poor collector properties at late stage of operation of field.
