摘要
根据川东北地区双侧向测井所取资料出现的失常幅度差异,文章从仪器工作原理、仪器操作参数选取和资料质量要求等方面进行叙述,通过分析影响资料的一些因素并结合仪器工作原理,对如何消除双轨现象进行了探讨。在实际工作中解决了川东北地区双侧向作业遇到的失常差异现象,为川东北项目工作开展取得认可的资料奠定了基础。
According to the abnormal amplitude excursion of DLL in north-east of Sichuan,this paper gives a summary in the aspects of instrument working principle,operation parameter selecting and log data quality requirement.In addition,this paper makes an analysis of the factors impacting the log data,discusses how to eliminate the double tracks and settles the problem in reality.The research result will be helpful to the DLL construction in north-east of Sichuan and makes a firm basis for obtaining the approved data by the first party.It helps the project run smoothly in north-east of Sichuan.
