CSAMT和测井联合约束反演在松辽盆地东南隆起区油页岩识别中的应用
Application of CSAMT and logging combined constrained inversion in oil shale identification in the southeast uplift area of Songliao Basin
摘要
Abstract
The seismic exploration of oil shale in Songliao Basin is difficult.Therefore,the application of controlled source audio magnetotelluric method and logging joint constrained inversion technology is carried out in the southeast uplift area of Songliao Basin.The research shows that the joint constraint inversion technology can divide and identify the oil shale and mud shale interbed as a relatively high resistance layer.Using this technology,it is found that the oil shale of the Nenjiang Formation in the study area is mainly distributed in the Halahai syncline,only locally deposited in the western part of the Denglouku anticline;the oil shale of the Qingshankou Formation is distributed in the Denglouku anticline and the Halahai syncline.The whole is characterized by the height along the Denglouku anticline axis and the gradual thinning along the two wings of the anticline axis,which points out the favorable direction for further exploration.关键词
