摘要/Abstract

摘要： 硼中子寿命测井是在中子寿命测井改进中发展起来的一种适应低矿化度地层的动态监测新技术。它是向地层中注入高俘获截面的硼酸,使中子寿命测井也适用于低矿化度地区。该技术通过暂时改变井筒附近地层水的性质,采用“测—注—测”工艺获取地层剩余油信息,直观解释产层的油水比例关系。根据硼中子寿命测井资料实施措施的通61-更40井和河68-24井取得了明显的增油效果。在油田开发进入中后期后,新区产能又接替不上的情况下,加快
硼中子寿命测井的探索和推广应用,挖掘潜力油层,具有重要的现实意义。

关键词: 硼中子, 寿命测井, 剩余油饱和度, 硼离差, 俘获截面

Abstract: Boron neutron lifetime log developed from neutron lifetime is a new technology of dynamic monitoring suitable for low salinity formations. It is generally used in cased hole for deter-mining remaining oil salutation of formation with salinity by in-jecting borohidrade with high capture section into formations.
The technology can acquire the information of remaining oil in formation using“log-injection-log”technique by changing the properties of formation water near wellbore temporarily. It can guide potential tapping of measures in single wells effectively. Obvious effectiveness of oil increment is achieved in well Tong
61-Geng40 and well He68-24 by implemented measures on the basis of boron neutron lifetime log data.

Key words: boron neutron, lifetime log, remaining oil sat-uration, boron deviation, capture section
