【摘要】 通过对研究区内100余口钻井测井资料的综合分析、20余口钻井岩心的详细描述、700多块薄片的详细鉴定,并充分利用地震资料,综合分析了研究区百岗组二段的岩石组合、沉积构造、剖面结构、生物化石、测井相和地震相等特征,认为研究区百岗组二段发育了扇三角洲和湖泊两种沉积相,扇三角洲主要发育在研究区的西北部和东北部,湖泊沉积相主要发育在研究区的南部。更多还原

【Abstract】 Based on data of the well logging,drilling core,thin section microstructure,seismic attributes,the authors analyse the petrology combination,sedimentary structure,section structure,biological fossil,logging facies and seismic facies of the second Member of Baigang Formation.All the results suggest that the sedimentary facies of fan delta and the lake should be developed on the north steep slope in eastern sag of Baise basin.As a typical sedimentary facies of steep slope,the fan deltas mainly distribute in the northwest and northeastern of the research area.更多还原
