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OA北大核心CSTPCD
Application of CSAMT and logging combined constrained inversion in oil shale identification in the southeast uplift area of Songliao Basin
松辽盆地油页岩地震勘探难度大,为此在松辽盆地东南隆起区开展可控源音频大地电磁法(CSAMT)和测井联合约束反演技术应用研究.研究表明,联合约束反演技术可以将油页岩与泥页互层整体作为相对高阻层进行划分识别.利用该项技术查明研究区嫩江组油页岩主要分布在哈拉海向斜,仅在登楼库背斜西部局部沉积;青山口组油页岩在登楼库背斜、哈拉海向斜均有分布,整体呈沿登楼库背斜轴高、沿背斜轴两翼逐渐减薄的特征,为进一步勘探指明了有利方向.
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.
