| 摘 要： | 从岩心分析入手,根据岩相及电性标志,确定了研究区的砾岩有效储层类型和发育特征。在此基础上,结合三次加密调整阶段的分级累产参数确定了八区下乌尔禾组油藏的储层划分标准。运用综合评价方法将全区储层分为4类,Ⅰ类储层最好,Ⅳ类储层最差。基于储层分类结果,实施了井网4次加密试验,结果表明:储层预测厚度的误差率在5%以内,储层类型符合率达到80%,设计产能达标率在90%以上。该方法的应用为进一步认识和评价特低渗透砾岩储层及油田四次加密井的全面实施奠定了坚实的地质基础,可广泛应用于其他同类油藏。

| Abstract: | The types and characteristics of effective conglomerate reservoirs in the lower Urho formation of Block 8 of Karamay oilfield have been defined according to reservoir cores,lithofacies and electric property.Reservoir classification standard has been established based on net pay identification combining with parameters of cumulative oil production from wells of different ranks during three times of infill adjustment.The reservoirs in the study area are classified into four categories through comprehensive ev... |
