摘要
鄂尔多斯盆地下寺湾地区油气资源丰富,而三叠系长7油层组发育大段烃源岩,有利于页岩气成藏。以地质学理论为指导,通过对下寺湾地区岩心资料、测井资料及文献调查,对鄂尔多斯盆地下寺湾地区长7段储层的地化特征、岩石学特征和孔隙特征进行研究。结果表明:研究区长7段泥页岩有机成熟度较高、空隙结构以粒间孔,粒内孔为主,且孔隙度较低。研究结果为鄂尔多斯盆地下寺湾地区长7段储层勘探开发提供依据。
The Xiasiwan area of the Ordos Basin is rich in oil and gas resources,while the Triassic Chang 7 oil-bearing formation develops a large shale formation,which is conducive to shale gas accumulation.Based on the geological theory,this study conducted the geochemical,petrological and pore characteristics of the Chang 7 Member Reservoir in the Xiasiwan area of the Ordos Basin through the investigation of core data,well logging data and literature in the Xiasiwan area.the study.The results show that the 7-segment shale has high organic maturity,intergranular pores,intragranular pores and low porosity.The research results provide a basis for the exploration and development of the Chang 7 Member Reservoir in the Xiasiwan area of the Ordos Basin.
