【摘要】 准噶尔盆地玛湖凹陷西斜坡二叠系风城组一段白云质岩为裂隙型储集层,在一些井中获得了高产油气流。在综合研究白云质岩优质储集层物性、孔隙结构及裂缝发育状况等石油地质特征的基础上,应用地震多属性,对该区白云质岩优质裂缝性储集层进行了刻画。并预测研究区风城组一段白云质岩在平面上发育3个优质裂隙储集层带,共计预测面积471 km2,为在该区进一步开展祥探提供了依据。更多还原

【Abstract】 The member-1 dolomitic rocks of the Permian Fengcheng formation in west slope of Mahu sag in Junggar basin belong to a fractured reservoir,from which high-yielding oil-gas flow has been obtained in some wells.This paper comprehensively studies the high-quality dolomitic reservoir and its geological features,by which describes such a high-quality and fractured reservoir in this area using seismic multi-attributes technique,and predicts that there are three high-quality and fractured reservoir zones in this member-1 dolomitic rocks,with an area of 471 km2,providing basis for further detailed prospecting in this area.更多还原
