准噶尔盆地南缘古近系—新近系沉积储层缺少系统性研究,其有利储层及规模分布不甚清楚。为此,应用测井资料、岩心资料分别进行标准化和岩心归位,分析岩心孔隙度与各种测井响应的关系及岩心孔隙度与渗透率的关系,通过回归分析建立孔隙度及渗透率测井解释模型。最后,根据试油资料,给出有效储层的物性下限为孔隙度大于8%、渗透率大于1mD,并结合沉积相带、岩性等控制因素,指出准噶尔盆地南缘古近系—新近系有效储层纵向上发育较好的层位主要是沙湾组二段、一段和紫泥泉子组三段,平面上则主要分布在车排子—卡因迪克地区、西湖—独山子—安集海背斜区及霍尔果斯—玛纳斯—吐谷鲁—呼图壁背斜区,为下步勘探部署提供了重要的参考依据。
The Paleogene-Neogene sedimentary reservoirs in the southern margin of the Junggar Basin lacks a systematic study, and the favorable reservoirs and their distribution are not clear. Therefore, the application of logging data and core data were normalized and core-reset respectively. The relationship between core porosity and various well logging responses and the relationship between core porosity and permeability were analyzed. Porosity and permeability were measured by regression analysis Well Interpretation Model. Finally, according to the oil test data, the lower limit of physical properties of effective reservoirs is that the porosity is more than 8% and the permeability is more than 1mD. Based on the control factors such as sedimentary facies and lithology, it is pointed out that the Lower Paleogene- The favorable reservoir in the vertical direction of the effective reservoirs is mainly composed of the second member of Shawan Formation and the third member of Zijinquanzi Formation, while the plane is mainly distributed in Chepaizi-Caine Dike area, West Lake-Dushanzi-Anji Sea anticline and the Horgos-Manas-Tugulu-Hutubi anticline, which provide important reference for further exploration and deployment.
