岩芯资料揭示上奥陶统良里塔格组碳酸盐岩台地发育滩相储层。本文利用钻井资料、测井资料和地震资料,通过对塔河油田良里塔格组滩体发育分布、储集空间和储层类型的深入研究;结果表明区内发育台内滩和台地边缘滩,滩体围绕台地边缘发育分布规模小;受到大气水溶蚀改造可形成溶蚀孔洞型储层,储集空间为溶蚀孔洞、粒内溶孔和铸模孔等,台地边缘滩体储层最为发育。 Core data reveal that the Upper Ordovician Lianglitage Formation carbonate platform platform beach facies. In this paper, drilling data, well logging data and seismic data are used to study the development distribution, reservoir space and reservoir types of the Lianglitage Formation in Tahe Oilfield. The results show that the inland developmental inland beach and the marginal beach on the platform The size distribution of the beach body around the margin of the platform is small. Due to the alteration of atmospheric water erosion, corroded hole-type reservoirs can be formed. The reservoir space is dissolved pores, intragranular dissolved pores and mold holes, and the platform reservoir is the most developed.
