鄂尔多斯盆地东缘上古生界页岩特征及含气量OA北大核心CSCDCSTPCD
Characteristics and Calculation Method for Gas Content of Upper Paleozoic Shales in the Eastern Margin of Ordos Basin
鄂尔多斯盆地上古生界石炭二叠系海陆过渡相泥页岩发育，前人对盆地内上古生界泥页岩已做了多项研究，而盆地东缘钻井资料较少，研究程度较低。为了弄清盆地东缘泥页岩的特征及含气性，通过野外实测剖面台头剖面的沉积、地化、岩性、物性等参数并结合等温吸附、核磁共振实验结果，对盆地东缘泥页岩进行分析。研究认为：盆地东缘上古生界以太原组发育的泥页岩最佳，厚度25 m左右，有机质丰度较高，处于产气态烃阶段，泥页岩中非膨胀性黏土含量较高，裂缝/微裂缝发育程度较均匀；同时…查看全部>>
Shale sequences are well developed in the Carboniferous-Permian transition facies,Ordos Basin. Researchers have done many studies on shales in upper Paleozoic of the Ordos Basin. With few drilling data,however,not enough researches have been carried out on the eastern margin of the basin. In order to clarify the characteristic and gas bearing of shales in the eastern margin of the basin,according to the characteristic of sedimentary,geochemistry,…查看全部>>
