摘要
储层的油气富集特征对油区"甜点"的预测具有重要的影响,对储层的下一步勘探部署具有重要的指导意义,采用铸体薄片、扫描电镜、高压压汞等测试手段,研究储层微观特征,它是影响储集层储集性能最重要的因素。本文采用统计分析的方法对储层各种微观特征与试油结果进行分析研究,结果表明:岩石矿物成分的石英含量、长石含量、岩屑含量与日产油呈正相关关系;孔隙填隙物含量及成分与试油呈一定的负相关关系;储层面孔率、平均孔径与试油有着一定的正相关关系,且相关系数较好,表明研究区储层储集空间多少及大小对储层含油性由着一定的正面影响。
Accumulation characteristics of oil and gas in the reservoir have an important influence on the prediction of "sweet spot"in the oil region, and have an important guiding significance for the next exploration and deployment of the reservoir. In this paper,the microscopic characteristics of the reservoir were studied by means of casting thin section, scanning electron microscope,high-pressure mercury injection and other test means. The results showed that the quartz content, feldspar content and cuttingscontent of rock mineral composition were positively correlated with the daily oil production. There was a negative correlationbetween the content and composition of pore interstitial matter and the oil test result. There was a positive correlation between planeporosity and average pore diameter of reservoir and oil test result, and the correlation coefficient was high, which indicated that thenumber and size of reservoir space in the study area had a positive influence on reservoir oil bearing.
