硼—中子寿命测井技术在中原油田的应用研究

硼－中子寿命测井是针对淡水油田的一项测井技术。但对中原油田高矿化度地层不的地层而言，由于开发时间较长，地层水矿化变化较大，用常规中子寿命测井方法很难取得较好的地质效果。本文针对中原油田实际情况，在实验基础上完善了盐水油田的硼－中子寿命测井技术。详细介绍了这一技术在定量求取剩余油饱和度、寻找出水层位、判断水级别等方面的应用，从而为准确监测油层纵横向动用状况、合理调整油田开发方案、优化油工作制度提供了可靠依据。

Application Research of B-Neutron Lifetime Logging Technlolgy in Zhongyuan Oilfield

B-Neutron Lifetime log is a king of technology that is directed against fresh water field.Neutron lifetime log is difficult to get good geologic feature for high formation water salinity in Zhongyuan Oilfield,due to the considerable chage of formation water salinity in longer development period.In according with the actual situation of Zhongyuan Oilfield,on the basis of experiment,the B-Neutron Lifetime log technology for salt-water field is consummated.This paper introduce in detail the application of the B-Neutron lifetime log to quantitative calculation of remaining oil saturation,seaking water/gas exit interval,and deciding the level of water out behavior,thus,the B-Neutron Lifetime log will provide a reliable foundation with monitoring accurately the production state of oil-bearing formation in verticat and horizatal,adjusting reasonably development plan of the field and optimummimg oil well production system.
