摘要:

以钻、测井等资料为基础,运用成因地层学和高分辨层序地层学原理,对长庆油田虎狼峁地区长6油层组进行层序分析,共划分为5个中期旋回,建立了研究区的等时地层格架。在此基础上进行单砂体的刻画,总结出单砂体的叠置方式为拼合型、迷宫型和孤立型等3种类型。对长6-1(1)小层进行地质建模,从建模结果来看,水下分流河道微相的物性好,孔隙度主要在12%~14%之间;河口坝的物性较好,孔隙度主要在11%~14%之间;其他微相物性较差,孔隙度在5%~10%之间。

Based on well drilling and logging data, by using the genetic stratigraphy and high resolution sequence stratigraphic theory, the sequences stratigraphy of Chang6 Reservoir in Hulangmao Area of Changqing Oilfield was analyzed, five mid-cycles were divided, isochronous stratigraphic framework was established in the study area, and single sandbody was depicted on the basis of the study. Superimposed, labyrinth and isolated types of sandbodies were summed up. Geological modeling was carried out for Chang6-1(1) subzone. Seeing from the simulation result, the property of underwater distributary channel microfacies is higher, and its porosity is ranged mainly between 12% and 14%; the property of estuarine bar is better, and its porosity is between 11% and 14%; the property of other microfacies is poor, and its porosity is between 5% and 10%.
