水平井随钻测井影响因素分析和校正

随着我国水平井钻井、测井、生产应用等技术的发展，水平井数量有了很大的增加。但在某些方面存在一些问题，本文就井眼，泥浆侵入，地层各项异性，围岩影响，井眼与地层的相对夹角，仪器本身等影响因素是如何影响随钻测井的展开研究分析，研究表明围岩和地层各向异性对随钻实测值影响最大，针对这两个影响因素建立校正程序，对失真的测井曲线进行处理，根据岩电关系验证处理校正后的曲线更加真实可靠。

Analysis of The Influencing Factors on Horizon well LWD and Correction

With China's horizontal well drilling, logging, production application technology development, the horizontal well there has been a great increase in number. But in some ways, there exist some problems in the wellbore, mud invasion, anisotropy of formation and surrounding rock strata, angle between well axle and formation, the instrument itself is how to influence factors as well logging with drilling expansion of research and analysis, research shows that rock and anisotropy were measured with drilling the biggest influence on these two factors, aiming at establishing correction procedures, logging curves of distortion process, according to rock-electr relation curves of validation processing after correction more reliable.
