硼中子寿命测井技术在层状断块油藏高含水期挖潜中的应用

Application of BNLL at high water-cut period in stratified block reservoir.

东辛油田以层状断块油藏为主 ,含油层系多 ,物性差异大 ,高含水期层间层内油水分布复杂。为改善高含水期油田开发效果 ,正确认识层间及层内剩余油状况 ,挖掘剩余油潜力 ,近几年利用硼中子寿命测井技术在剩余油的监测方面进行了积极的探索 ,取得了显著的效果。

Dongxin oil field belongs to stratified block reservoir, and the difference of physical properties are evident. Because it is in high water cut developing period, the distribution of oil and water is complicated. In order to improve the exploring result and to understand and excavate the residual oil exactly, we have searched the technique of BNLL (Boron Neutron Lifetime Log) in recent years and received prominent effect.
