用3220机对碳酸盐岩剖面测井资料进行数字处理时,主要是用复杂岩性分析程序CRA。辽河油田测井系列不完善。在CRA程序中虽然设计了用补偿中子—密度交会、中子—声波交会求孔隙度等,但由于缺乏补偿中子曲线(CNL)而不能实现。辽河油田每口井都测中子伽玛曲线(NGR),因此可将NGR转换成CNL,以弥补目前孔隙度测井系列不全之不足。在此基础上,设计并调试了LCRA程序。此程序的主
When using the 3220 to digitally process carbonate log data, the CRA is used primarily for the complex lithology analysis program. Liaohe oilfield logging series is not perfect. Although the design of the CRA program uses the compensated neutron-density intersection and the neutron-acoustic interaction to obtain the porosity, it can not be realized due to the lack of a CNN. The neutron gamma curve (NGR) is measured in every well in the Liaohe Oilfield, so NGR can be converted to CNL to make up for the insufficiency of the current porosity logging series. On this basis, LCRA program was designed and debugged. The main program
