摘要
依据准噶尔盆地彩南油田C135井区三工河组二段的动、静态资料建立了三维地质模型。利用静态地质资料分析了C135井区的区域应力成因机制背景,完成了储量复算,确定研究区地质储量合计67.81×104t。利用开发动态资料探讨了三维地质模型的应用,结合储层非均质性研究认为,研究区剩余油主要分布在C135井区三工河组二段第3小层,集中在变异系数和级差大的砂体中。认为低幅度构造油藏容易造成底水锥进,研究区目前采液速度过高,含水率上升较快,通过数值模拟确定合理采液速度为7%,对于注水见效的油井应当控制注水井注水量,防止油井水淹。
Reservoir characterization based on 3Dgeologic modeling is an important project for oilfield development when it comes to the medium-late stage of reservoir development.The 3Dgeologic model of the 2nd member of lower Jurassic Sangonghe formation in Wellblock Cai135 of Cainan Oilfield is established based on the static and dynamic data.The areal background of stress mechanism is analyzed and geological reserves are recalculated through the static geologic data of Wellblock Cai135.Oil in place of the study area is 82.94×104t.Integrating the dynamic data,the use of 3Dgeologic model is discussed.Combined with the investigation of reservoir heterogeneity,it is assumed that remaining oil is concentrated among wells where the variation coefficient of permeability and permeability ratio are big in the layer J1s2-12of Wellblock Cai135.Liquid production rate of the study area is very high and the water content increases very fast.The rational liquid production rate is 7%,which is calculated from numerical modeling.To prevent the production wells from water flooded,the amount of water injection should be controlled when the water injection wells affect production wells distinctly.
