埕岛油田馆陶组上段属河流相砂岩 ,油气富集程度高 ,该层系已探明石油地质储量占埕岛油田总储量的 89.6% ,产能高 ,原油性质相对较好 ,该油田目前仍处于天然能量开采阶段。通过对馆上段油藏的综合分析 ,建立了高度概括的油藏概念地质模型 ,认为馆上段河道砂油藏为曲流河相正韵律细粒沉积为主 ,具有高孔隙度、高渗透率、高黏度、高饱和度、高非均质程度等特点 ,砂体变化快 ,油层疏松易出砂。采用测井约束地震反演与井资料密切结合 ,建立了描述储集砂体分布和油藏属性参数特征的静态地质模型 ,采用随机模拟方法建立了馆上段 1+2砂组至 6砂组的三维定量地质模型。图 1参 3(徐英霞摘 )
The Upper Guantao Formation in Chengdao Oilfield is fluvial facies sandstone with a high degree of oil and gas accumulation. This layer has proven oil geological reserves accounting for 89.6% of the total reserves of Chengdao Oilfield, with high productivity and relatively good crude oil properties. Currently, In the natural energy exploitation stage. Through the comprehensive analysis of the reservoir in the upper section of the reservoir, a highly generalized conceptual reservoir geological model has been established. It is believed that the channel sand reservoirs in the upper section of the reservoir are dominated by rhyolite fine sediments with high porosity, high permeability and high Viscosity, high saturation, high degree of heterogeneity and other characteristics of the sand body changes quickly, easy to sand out of the reservoir. Using well logging constrained seismic inversion and well data, a static geologic model describing the characteristics of reservoir sand distribution and reservoir attribute parameters was established. Stochastic modeling was used to establish the upper member of the Upper Member 1 to 2 sand group to the 6th sand group Three-dimensional quantitative geological model.
