HZ油田阜三段低渗透砂岩储层流体测井识别及储层级别划分方法研究

Fluid logging identification method and reservoir level division method of low permeability sandstone reservoir in Fu-3 section of HZ oilfield

依据高邮凹陷HZ油田阜三段低渗透砂岩储层的特点,分区块进行储层流体识别,并结合地质、岩心、测井、试油及试采等资料,通过对储层参数与储层级别划分敏感性分析,构建了储层级别划分的综合评价指数,从而建立阜三段低渗透储层的储层级别分类标准。通过试油对比分析表明:所建评价方法计算精度较高,满足了该区阜三段低渗透储层流体识别及储层级别划分的需要。

According to the characteristics of low permeability sandstone reservoir of Fu-3 section in Gaoyou sag of HZ oilfield, res-ervoir fluid was identified according to partitions. Combining with data, such as geological, core, logging, oil testing and producing test, though sensitivity analysis of reservoir parameters and reservoir level division, comprehensive evaluation indexes were set up. Therefore, reservoir level classification criteria of low permeability reservoir of Fu-3 section was established. Oil testing analysis shows that the evaluation method has high calculation accuracy, which can meet the demands of fluid identification and reservoir level division in this area.
