石油是聚集在储集层中的,用现代物理化学测试仪器来研究储油砂岩是石油地质勘探中极其重要的方面。本文着重介绍研究砂岩储集层的热解色谱技术,全文包括三部分:1.研究了不同含油级别砂岩的热解、热解-气相色谱和热解模拟特征;2.确定了生产层、低产生产层和非生产层间的热解参数界限值;3.提出了用热解参数计算残余油饱和度的新方法。
Oil is concentrated in reservoirs. The use of modern physical and chemical testing instruments to study oil-bearing sandstones is an extremely important aspect of petroleum geological exploration. This article focuses on pyrolysis chromatography technology for studying sandstone reservoirs. The full text includes three parts: 1. The characteristics of pyrolysis, pyrolysis-gas chromatography and pyrolysis of sandstone with different oil-bearing grades are studied; 2. The production layer, The limit of pyrolysis parameters between production and non-production layers; 3. A new method to calculate the residual oil saturation by pyrolysis parameters is proposed.
