| 摘 要： | 气体介质下测井项目优化的问题日益突出。针对各种测井仪器测量原理及受气体介质的影响因素分析,得出自然伽马、感应、核磁共振以及井径、井斜、井温等测井项目在气体介质条件下测井可以正确反映地层信息并较好地进行储层解释,是获取孔隙度信息、确定产气层位的最佳测井方法,应成为气体介质下测井项目的优化选择;双侧向、电阻率成像、地层倾角、自然电位、声波、补偿中子等测井项目不适用于气体介质测井;岩性密度测井在井眼规则条件下适用于气体介质下测井,在井眼不规则的情况下受影响较大,不适用于气体介质条件下测井。

| Abstract: | In recent years,as the increase in drilling mediums in Sichuan oil & gas field,logging projects optimization in the gas mediums has become a very difficult problem.By analysing various logging tools measuring principles and influence of the gas mediums on the tools,it is found that in the gas mediums the natural gamma ray log,induction log,NMR log,caliper log,inclination log and well temperature log may correatly reflect formation information and provide better reservoir interpretations.All these logs are t... |
