摘要
为解决补偿中子测井易受到复杂井况影响导致测井曲线失真问题,以ECLIPS5700测井系列补偿中子测井仪为例,针对大港油田测井施工情况,分别从井径、泥浆矿化度、泥饼、间隙、地层流体、套管、岩性等方面进行了阐述,并利用FORWARD解释平台进行系统校正与对比分析,基本消除了复杂井况对补偿中子测井曲线的影响。
In order to solve the problem that compensated neutron logging is vulnerable to complex well conditions and leads to the distortion of logging curves,taking Ecilips5700 series compensated neutron logging tool as an example,in view of the logging operation in Dagang Oilfield,the analysis is made from the aspects of borehole diameter,mud resistivity,mud cake,gap,formation fluid,casing,lithology,and so on,and the FORWARD interpretation platform is used for systematic correction.By contrast,the influence of complex well conditions on compensated neutron logging curves is basically eliminated,which provides examples and references for the treatment of similar well conditions in the future.
