摘要: 在阜新刘家区以往钻井勘探等方面地质工作的基础上,发现阜新盆地埋藏大面积页岩,页岩气成藏与开发潜力巨大。利用阜新刘家区沙海组页岩实验室岩芯测试数据,分析了沙海组页岩的分布、有机碳含量、Ro、孔隙度、脆性矿物含量、裂隙特征等重要参数。得出刘家区沙海组页岩厚度为500~600 m,有机碳含量为2.14%,热成熟度为0.634%,平均孔隙度为3.46%,脆性矿物中,石英含量达37.21%,裂隙发育好,存在多种形式的纳米级孔隙和天然裂缝。根据有机碳含量、Ro等参数,采用资源丰度类比法估算出刘家区页岩含气量为(72.8~89.05)×108 m3。通过对刘家区沙海组页岩气的分析和资源评价,可为刘家区页岩气的勘探开发提供必要的基础参数,确定阜新刘家区为页岩气勘探开发的有利区域。

Abstract: Based on the previous geological work in Liujia Area,Fuxin,we found that there buried large-scale shales in Fuxin Basin,where accumulation of shale gas is of very huge potential for development. After shale core sampling and laboratory tests of the shale of Shahai Formation in Liujia Area, Fuxin, we analyzed the important parameters of distribution, organic matter content, Ro, porosity, brittle mineral content, and fracture characteristics. The research results show that the shale thickness is 500~600 m, with organic carbon content of 2.14%, thermal maturity 0.634%, and the average porosity 3.46%. Among the brittleness minerals, quartz content accounts for 37.21%, and there are many forms of nanoscale porosity and natural fractures proving that fracture development is very good. According to Ro and organic matter content, it is estimated the shale gas in Liujia Area is(72.8~89.05)×108 m3 by resource abundance analogy method. It is provided the necessary basic parameters for the exploration and development of shale gas in Liujia Area by the analysis and resource evaluation of shale gas of Shahai Formation, and Liujia Area in Fuxin can be determined as favorable areas for shale gas exploration and development.

Key words: shale gas, characteristics of shale, organic carbon content, thermal maturity evolution degree, resources potential evaluation
