火烧山构造上二叠统平地泉组属于以次生溶蚀孔隙为主的储集层。次生溶蚀孔隙的形成与胶结物、交代物——方沸石的溶蚀作用直接有关;它的发育程度与自生方沸石形成时期、含量等有关。本文就平地泉组6口井共326块的岩矿、铸体、荧光薄片,并应用电镜扫描、能谱、X衍射、物性及有关地球化学参数等,根据有关成岩后生作用的研究方法和成岩阶段的划分标志,对该储层的成岩后生变化、控制作用和含油性进行初步研究。
The Upper Permian Pingdiquan Formation in the Huoshaoshan Formation belongs to the reservoirs dominated by secondary dissolution pores. The formation of secondary dissolution pores is directly related to the dissolution of the cementation material and calcite, and its development degree is related to the formation time and content of the authigenic zeolite. In this paper, a total of 326 rocks, castings and fluorescent sheets from 6 wells in Pingdiquan group were studied. According to the research methods of diagenesis and diagenesis based on the scanning electron microscopy, energy spectrum, X-ray diffraction, physical properties and related geochemical parameters, Stage of the division of the diagenesis of the reservoir after the change, control and oil-containing preliminary study.
