以临汾区块煤层气测井资料,对临汾区块5#煤层段进行精细研究。利用构造煤与原生结构煤测井响应差异性,对所收集的钻孔测井曲线进行分析,综合对比各个钻孔得到构造煤分布。结果表明:该地区构造煤较发育,主要分布在西部古驿-窑渠背斜两翼及东部紫金山断裂带,东部构造煤厚度最大值可达2.0m,中部构造煤厚度小于0.5m,大部分区域构造煤厚度在1～1.5m之间,垂向上5#煤层构造煤主要分布于煤层中下部,大体分两个构造煤小层,部分区域分1个或3个小层。
Based on the data of coalbed gas well logging in Linfen block, the 5 # coal seam section of Linfen block is studied carefully. Utilizing the difference of well logging response between constructed coal and primary structure coal, the collected borehole logging curves are analyzed and the tectonic coal distribution is obtained by comprehensive comparison of each borehole. The results show that tectonic coal is more developed in this area, which is mainly distributed in the two wings of the ancient Guyi-Kao canal anticline in the west and the Zijinshan fault zone in the east. The maximum thickness of tectonic coal in the east reaches up to 2.0m and the thickness of tectonic coal in the middle is less than 0.5m. The thickness of regional tectonic coal is between 1 and 1.5 m, and vertical coal seam 5 is mainly distributed in the middle and lower part of coal seam, roughly divided into two small layers of coal and some areas are divided into 1 or 3 small layers.
