为解决三塘湖盆地火成岩岩性识别问题,推动岩屑录井由定性向定量发展,吐哈录井引进X射线荧光分析仪,以三塘湖盆地火成岩识别及储层识别评价为研究目标展开实验分析。通过对M215井、M49井、M53井以及T23井、T26井等17口评价井、探井的X射线荧光随钻录井技术分析,初步实现了三塘湖盆地沉积岩、火成岩岩性的识别,形成了一整套三塘湖盆地岩性识别图版,进一步结合测井、分析化验等各类资料,初步形成了储集层物性的评价分析,找到了一套适合于三塘湖盆地火山岩地层录井作业的有效方法,并在实际操作中取得了积极的成效。
In order to solve the problem of igneous lithology identification in Santanghu basin and promote the quantitative and quantitative development of debris logging, X-ray fluorescence analyzer was introduced in Tuha Logging Center to investigate the igneous rock identification and reservoir identification in Santanghu Basin as the research goal experiment analysis. Through the analysis of X ray Fluorescence with Drilling Logging technology of 17 evaluation wells such as M215 well, M49 well, M53 well, T23 well, T26 well and exploration well, the lithology of sedimentary rocks and igneous rocks in Santanghu Basin has been preliminarily identified and formed A set of lithologic identification plates of the Santanghu Basin was further developed. Based on various data such as well logging and analytical tests, the reservoir physical properties were initially evaluated and analyzed, and a set of logging data suitable for volcanic logging in the Santanghu Basin was found Effective method, and in the actual operation has achieved positive results.
