沁水盆地与鄂尔多斯盆地上古生界泥页岩储层对比分析

Mud Shale Reservoir Comparison of the Upper Paleozoic in Qinshui Basin and Erdos Basin

摘要: 沁水盆地是我国重要的含煤盆地之一，鄂尔多斯盆地是我国重要的含油气盆地。随着中国经济的快速发展，对油气资源的需求越来越高，页岩气是未来重要的补充能源，这两个盆地均发育多套泥页岩层，其中山西组与太原组等均有可能形成页岩气藏，因此对这两个盆地泥页岩储层进行对比研究具有重要意义。笔者重点关注了泥页岩评价指标中的总有机碳、有机质类型和成熟度、泥页岩中脆性矿物含量及孔渗方面和微孔隙等的特征，通过有机地球化学及泥页岩储层特征的对比，最终得出鄂尔多斯盆地山西组及太原组泥页岩储层均优于沁水盆地，为以后的勘探开发提供了重要参考。

Abstract: Qinshui basin is one of the important coal basin in China; Erdos basin is an important oil and gas basin in China. With the rapid development of Chinese economy, demand for oil and gas resources is much higher. Shale gas is an important additional energy in the future. The two basins develop many sets of shale bed, of which Shanxi group and Taiyuan group may form shale gas reservoirs, so it is of great significance to make a comparative study of the two basin shale reservoirs. The author focuses on Total Organic Carbon, organic matter types and maturity, the characteristics of brittle mineral content and porosity, permeability and micropores in the evaluation of mud shale, through the comparison of organic geochemistry and shale reservoir characteristics, and finally obtains the mud shale reservoirs of Shanxi formation and Taiyuan formation in Erdos basin are better than which in Qinshui basin, which provides an important reference for the following exploration and development.
