油田注水开发中期,油井普遍注水受效,对于分层注采井组,不能明确注水主要见水层段,使开发方案制定增加难度。水驱前缘监测技术以摩尔-库伦理论和断裂力学等为理论依据,以油水井间微地震监测为手段,能够描绘出分层段的裂缝展布状况、水驱主流方向以及水驱前缘波范围。
In the mid-term of oilfield waterflooding, the oil well generally receives water and is ineffective. For the stratified injection-production well group, the waterflooding section can not be clearly identified and the development plan is made more difficult. Based on the Mohr-Coulomb theory and fracture mechanics, the monitoring technique of waterflooding front can be used to describe the distribution of fractures in stratified sections, the main direction of waterflooding and the leading edge of waterflood Wave range.
