Characteristics and evaluations of reservoirs in Carboniferous-Permian, Northeast China

摘要: 通过大量的野外观察以及露头样品的微观分析和物性测试,对东北地区石炭—二叠系的储层条件进行了初步分析。东北地区石炭—二叠系分布广泛,海相、陆相均很发育,总体上具有从石炭到二叠系由海相向陆相转变的规律;地层以灰岩和碎屑岩为主,局部地区为火山碎屑岩。东北地区石炭—二叠系储集性能较差。石炭系Ⅰ类储层主要分布在二连的西南部,Ⅱ类储层主要分布在二连东北部以及松南的磐石一带,Ⅲ类储层主要分布于三江以及松北部分地区;二叠系Ⅰ类储层主要分布在松北的伊春附近以及二连的林西官地,Ⅱ类储层主要分布于二连东部的西乌珠穆沁旗附近以及松南的永吉附近,Ⅲ类储层主要分布在内蒙古的镇赉县附近。Abstract: According to field observations and outcrop sample tests,the conditions of Carboniferous-Permian reservoirs in Northeast China have been studied.Carboniferous and Permian strata are widespread in Northeast China.Both marine and continental facies are found and the marine facies changes to the continental facies from Carboniferous to Permian.Limestone and clastic rock are the dominant formation compounds,and in some region,pyroclastic rock accounts for the largest proportion.The reservoir conditions of Carboniferous-Permian are usually poor.As to Carboniferous strata,the type-Ⅰ reservoirs mainly locate in the southwest of Erlian city,and the type-Ⅱ in the northeast of Erlian city and in Panshi city(south of the Songliao Basin),and the type-Ⅲ in Sanjiang county and the north of the Songliao Basin.As to Permian strata,the type-Ⅰ reservoirs distribute in Yichun city(north of the Songliao Basin) and Guandi town of Linxi county of Erlian city,and the type-Ⅱ around West Ujimqin(east of Erlian city) and Yongji county(south of Songliao Basin),and the type-Ⅲ around Zhenlai county of Inner Mongolia.
