鄂尔多斯盆地贯屯区油藏长2段储层测井解释
|
摘要
测井分析解释是评价储层、计算油藏储量的必要技术手段,针对鄂尔多斯盆地贯屯区油藏长2段储层开展了二次测井解释分析,确定了有效储层厚度下限门槛值。研究表明,长2段储层有效孔隙度下限为10%,声波时差下限为228.5μs/m,透率下限为1×10-3μm2,电阻率下限为18.4?·m,含油饱和度为31.9%。
Logging analysis and interpretation are the necessary technical means for evaluating reservoir and calculating reservoir reserves. Secondary log interpretation and analysis were carried out for Chang2 reservoir in Guantun area of Ordos basin, and the threshold of lower limit of effective reservoir thickness was determined. The results showed that the lower limit of effective porosity was 10%, the lower limit of acoustic wave time difference was 228.5 μs/m, the lower limit of permeability was 1.0 ×10-3 μm2, the lower limit of resistivity was 18.4 ?·m, and the oil saturation was 31.9%.
