4) logging while drilling(LWD)
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.

3.
Stratum data acquired from LWD(logging-while-drilling),because of the two characteristics of immediacy and authenticity,have favorabe dominance in log evaluation of horizontal well,and can be used to effectively distinguish stratum,oil and gas r.
LWD(随钻测井)是在地层刚被钻开、泥浆侵入刚开始时进行的,所得数据具有即时和真实两大特性,所以将其用于水平井测井评价有着得天独厚的优势,可以有效地判别地层、识别油气层(特别是天然气储层)。
补充资料：电位降法测电偶电流
分子式：
CAS号：
性质：一种测定金属电偶腐蚀的简易方法。在被测的电偶对之间接一个已知的低阻值电阻，电偶电流流过时测定电阻两端的电压降，即可算出电偶电流，分析电偶腐蚀的行为。优点：设备简单易得；缺点：由于有一个电压降，故测出的电偶电流总是比电偶对完全短接时的实际电偶电流小。
