摘　　要：以樊庄区块3口煤层气井和临兴区块1口煤层气井为研究对象,通过分析这4口井的储层物性参数和工程数据发现,随着深度的增加,储层压力、破裂压力、裂缝高度、平衡产水阶段的排采时间都随之增大,但是裂缝延伸长度随之减小。深部煤层和浅部煤层物性差异导致二者的工程差异性,相对于浅部煤层,深部煤层对开发工程具有更高的要求。Takes 3 CBM wells in Fanzhuang block and 1 CBM well in Lmxmg block as the research object, by analyzing the reservoir physical parameters and engineering data of these four wells, it is found that with the increase of depth, the reservoir pressure, fracture pressure, crack height, and the production time of balanced water production stage all increase, but the crack extension length decreases. The differences in physical properties between deep coal seams and shallow coal seams lead to engineering differences, compared with shallow coal seam, deep coal seam has higher requirement for development project.
