中子寿命测井技术的发展

Advances in Neutron Lifetime Log

过去几年中,核测井技术受石油勘探开发需要的推动,借助现代电子和信息技术的新成就,发展十分迅速。硼中子寿命测井方法在淡水低孔低渗砂岩储层中确定剩余油饱和度方面取得的成效使得中子寿命测井近年来成为国内热点之一。文章综合评述了近些年中子寿命测井的重大进展。

Driven by the need of petroleum exploration and production,today′s nuclear well logging technology has been developing rapidly in the past few years with the aid of modern electronics and information technology.Boron neutron lifetime logging method(NLL)has good results in identifying the remaining oil saturation in freshwater low porosity and low permeability sandstone reservoirs.This makes NLL in recent years become the hot one.This paper provides an overview of recent advances in NLL.It′s very helpful for current research and production.
