随钻测井
1.
The comparison between logging while drilling(LWD) and wireline logging(WL) curves of a oilfield shows that: the depth,value of resistivity,and distribution range of density of the LWD measurements are rather close to that of WL,invasion effect in LWD is less than that in WL,so LWD can provide more credible information for oil-gas interpretation and formation evaluation.

补充资料：岩性密度测井
用γ源发出的γ射线被岩石原子吸收后，原子放出电子。岩石原子吸收γ射线的截面(称光电吸收截面)除以岩石的原子序数，为有效光电吸收截面指数Pe；根据各种岩石Pe值的不同，可区分出不同的岩性。本法适用于裸眼井，除探测岩性外，还可测量岩石的体积密度。
