魏斌柯启宇够：中深部天然气层识别及其分布特征，测井技术，１９９６（４）２０，２４４～２４９。中、深部气层在测井资料上难以识别。本文从测井曲线环境校正和侵入校正着手，利用有效孔隙度差值交会法、视流体时差与视流体密度比值法等较准确地识别气层，提高了解释符合率。在此基础上用多并评价方法对气层在纵向和平面方向上的分布特征进行了研究，发现了新的含油气构造。
It is difficult to identify mid and deep gas zones with well-log information. A gas zone determination method is presented, which begins with enviromental and invasion correction utilizing difference crossplot of effective porosities and the ratio of apparent fluid time difference to apparent fluid density. On the basis of crossplot and ratio methods, the features of gas zone distribution in both horizontal and vertical direction by means of multiwell evaluation. New oil and gas bearing structures have been found.
