| 摘 要： | 安塞油田H区为低孔、低渗油藏，经过10多年的注水开采，己进入开发中后期，开发矛盾日益明显。分析总结安塞油田H区长6储层地质和沉积微相特征后，指出研究区属三角洲前缘亚相沉积，并详细分析了区内出现的三角洲前缘水下分流河道、河道侧翼、分流间湾、河口坝、水下天然堤和前缘席状砂等六种沉积微相的岩性、电性特征。最后采用指示模拟的方法建立了研究区的沉积微相模型，并以此模型为基础建立了研究区的储层参数模型。验证结果表明，在相控条件下所建模型与实际地质情况符合较好，为成功挖潜剩余油提供了保证。

| Abstract: | The reservoir of Ansai oilfield was low porosity and low permeability reservoir. The characteristic of the reservoir and microfacies of Chang6 reservoir in H area of Ansai oilfield was analyzed, and the characteristic of the six microfacies include underwater channel, riverside, interfluve, debouch bar, underwater lateral levee, and sheet sand in the area were analyzed in detail. The facies model and reservoir model of the study area were built up by using lots of indicators. The results of the modeling show that ,under the control of facies model, the reservoir model can show the facts underground better, and the model is fit for the work for developing the remaining oil. |
