塔河油田良里塔格组滩相储集体研究
|
摘要
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。
Bank reservoir is the important goal of south exploration in Tahe oilfield,and the core datareveals that the bank reservoir developed in the Upper Ordovician Lianglitage Formation carbonateplatform.In this paper,it takes advantage of the drilling data,logging data and seismic data,throughstudying the distribution of bank,reservoir space and reservoir types of Lianglitage formation in TaheOilfield in depth,the results show that bank within the platform and the bank of platform edge have beendeveloped within the region,and the bank body are strips arranged aroud the edge of the platform withsmall scale;vuggy reservoir can be formed by the transformation of meteorological water solution,and thereservoir spaces are corrosion holes,grain dissolution porosity and mold inside the hole and so on,thebank reservoir would be best developed along the edge of the platform.
