diameter gamma-neutron logging tool as well as high pressure wellhead seal assembly made by Halliburton are selected for this task.
江苏金坛盐穴地下储气库井腔体试压密封检测需要精确监测套管和测试管柱之间的环形空间中气水界面位置的变化情况,为此选用了哈里伯顿公司生产的DDL-Ⅲ数控测井系统和直径111/16in的伽马中子测井仪以及配套的井口密封设备。
Source spacing is one of the key parameters of neutron logging tool, by which permeability precision, sensitivity, resolution of the logging tool are determined to a large extent.
源距是中子测井仪器的主要参数,它在很大程度上决定测井仪的孔隙度精度、灵敏度、分辨率以及环境因素影响状况。
Ordinary existing logging methods involve three kinds of porosity logging data from acoustic, density and neutron loggings; however, only one kind of data are used in usual logging data interpretation to lose a great deal of very useful informations.
为此，本文利用声波测井、密度测井和中子测井的读数建立了三种孔隙率测井资料解释的联立方程，并用克莱姆法则（Cramer定律）给出最终求解的公式。
