濮城油田文51块剩余油挖潜配套技术

The Complete Sets of Technique of Production Potential in Fault-block Wen 51 in Pucheng Oilfield

濮城油田文 5 1断块是一个典型的多油层非均质复杂断块油藏 ,长期注水开发造成井况损坏严重 ,注采井网遭到破坏 ,剩余油集中在井况损坏区、断层高部位、注水切割区及河道砂体注入水流线未波及的井间滞留区。剩余油的挖潜依靠多元化配套技术 ,完善注采井网 ,扩大注水波及体积 ,提高水驱控制储量和动用储量 ,从而提高区块采收率。

The fault-block Wen 51 is a typical multi-zones heterogenous complex reservoir.It was taken a long-time to water flood development , which makes severe damage of hole conditions and injection-production patten.The remaining oil concentrared around the regions of damaged wells、tall positions of fault-block、water injection cutting regions,and regions which water unswept inside the hold-up areas in river-channel sand bodies.The tap production potential of reservoir must depend on complete sets of polytechnic methods to complete injection-production patten,enlarge the water-swept volume,increase the water-drive controlling reserve and producing reserve which to enhance recovery of reservoir.
