摘　　要：针对准噶尔盆地砾岩油藏岩性变化快,砂砾岩体分布复杂,储层非均质性强的特点,以克拉玛依油田八区克上组油藏为例,将沉积微相模型与岩石相模型耦合,得到基于储层成因和岩性成因的岩石相模型,建立了成因岩石相模型约束下的储层参数模型。这种针对砾岩油藏三维精细相控储层建模的研究思路和方法,较好地表征了储层的强非均质性,为油藏开发调整及剩余油分布预测提供了参考,对同类地质特征的储层建模具有借鉴意义。Aiming at the characteristics of fast changing lithologies,complex conglomerate distribution and serious heterogeneity in conglomerate reservoirs of Junggar Basin,Upper Karamay Formation reservoir in No.8Region of Karamay Oilfield was taken as an example,model based reservoir genetic types and lithologies were established by using sedimentary microfacies model coupling with lithologic facies model,more accurate reservoir attribute parameter models constrained by genetic rock facies model were established.The idea of 3Dfine modeling for conglomerate reservoirs better characterizes the reservoir heterogeneity,it provides reference for reservoir adjustment and prediction of remaining oil distribution and as well as for modeling the reservoirs with the same geological characteristics.
