| 摘 要： | 碳酸盐岩缝洞型油藏非均质性强，储集空间多样，应用常规产能指标对其进行产能评价具有诸多困难，如井底流压不易准确获得，地层压力下降较快且分布不均等，求取的采油指数也无法真实反映单井的生产能力。因此，建立了一种简单实用的碳酸盐岩缝洞型油藏产能评价方法．根据大量统计资料，经线性回归。得出产量与井口油压的经验关系式，其斜率定义为产能系数，反映了产量对油压的依赖程度，也反映了单井生产能力的大小。结合碳酸盐岩缝洞型油藏生产特征，建立了产能评价标准，按产能系数大小将单井产能划分为4级：大于8t／（d·MPa）为高产能井，6～8t／（d·MPa）为中等产能并，4～6t／（d·MPa）为低产能井，小于4t／（d·MPa）为特低产能井。对哈六区块3类典型单井进行了实例分析，评价结果与实际情况相符．应用效果较好。

| Abstract: | There are some actual difficulties in deliverability evaluation of fractured-vuggy carbonate reservoir with conventional capacity index due to its severe heterogeneity and space types of various reservoir,such as not easy to get bottom hole flowing pressure precisely,reservoir pressure declines fast and distributes nonuniformly.According to numerous oilfield data,a simple and practical deliverability evaluation method is established in this paper.An output-pressure empirical correlation is obtained via line... |
