文明寨油田“双高”开发期保持稳产的途径

Steady Oil Production Measures to Wenmingzhai Oilfield in High Water Cut and Recovery Percent.

针对文明寨油田局部构造认识不清、层间动用状况差异大、剩余油分布规律复杂、井况恶化等各种矛盾 ,介绍了油田高含水、高采出程度开发期保持连续 5a稳产的途径 ,阐述了以强化构造认识 ,加大注水、产液结构调整 ,加强剩余油分布规律研究为主的各种具体方法和措施 ,进一步总结了油田开发取得的显著效果 。

Aimming at varies contradictions existing in the stage of high water cut and high recovery percent,for instance,the understand to the local structure of Wenmingzhai Oilfield being unclear,the status of produced interbedded oil being very different,the regulation of distributing of residual oil being complex, well's condition being worse,this paper introduces the measures to keep the oilfield production steadily in continuous five years in the stage of high water cut and recovery percent,expound a series of measures to strengthen the understand to underground structures,increase water injection,adjust the structure of producing liquid,strengthen the study of the distributing regulation of residual oil, the remarkable effect in development was summed up, sothe measures provides a reference to keep the production steadily in the stage of high water cut for this kind of oilfield.
