摘要
准确地识别随钻电阻率测井环境影响因素的主次是有针对性地进行环境影响校正的前提。系统分析了影响随钻电阻率测井的环境影响因素,介绍了根据相位和幅度电阻率曲线的分离形状来判断影响因素的过程,在吸收国内外相关研究成果的基础上,系统直观地给出了随钻电阻率测井环境影响因素的判释流程,并结合实例进行了验证,证明该判释流程是合理可行的。
Distinguishing the primary factors from environmental influential factors affecting logging-while-drilling resistivity is a perquisite to environmental correction.In this paper,the author summarized the environmental factors affecting LWD resistivity,and proposed to distinguish the factors by the separation between phase and amplitude resistivity curves.A workflow for identifying factors affecting LWD resistivity has been established by assimilating previous studies,and it has been verified with real data.
