摘要
为了快速地识别十屋断陷碎屑岩岩性，利用测井资料和岩心资料，选取自然伽马、深侧向电阻率、声波时差和密度测井等数据编制出测井曲线交会图版，该图版包括砂泥岩识别图版及砂岩识别图版。利用此图板对十屋断陷深层泥岩、粉砂岩、砂岩和砂砾岩进行识别，结果与实际岩性相吻合。说明测井资料交会图法在十屋断陷碎屑岩岩性识别中的应用是切实可行的。
In order to quickly recognize the lithology of Shiwu Fault Depression, with the help of data of both well logging and core analyses and moreover by choosing logging data such as natural gamma, deep laterolog, interval transit time, Densilog and so on, the crossplot board of logging curve has been compiled. The board includes both sandy mudstone recognizing board and sandstone recognizing board. The identifications of mudstone, siltstone, sandstone and glutinite in the deep part of Shiwu Fault Depression are conducted with the help of the above board. The results are accordant with actual lithology. This fact proves that the usage of the crossplot method is practical in the clastic rock＇s lithology identification in this region.
