为研究压裂位置对底板高含水的煤层气井产量的影响，以韩城区块11^#煤层为研究背景，采用Petrel地质工程一体化软件，模拟顶板、顶板+煤层、煤层3种压裂位置对煤层气井的产量影响规律。结果表明：当煤储层距离高含水层1、5 m时，3种压裂方式均呈现低产气量、高产水量、见气时间晚的特征；当与含水层距离增大至10、15 m时，气井产水、产气量变化幅度较小。在高含水底板层影响下，3种压裂位置的累计产气量由大到小为：顶板>煤层+顶板>煤层，其中顶板压裂日产气峰值高，见气时间短、产水量低，受高含水层的影响较小，更适合底板高含水的煤层气井压裂改造。在韩城矿区对3种压裂位置进行了现场验证，证明了模拟结果的准确性，研究成果可以为高含水底板煤层压裂位置优选提供指导。

In order to study the influence of fracturing location on the production of coalbed methane wells in floor with high water content, the 11^# coal seam in Hancheng Block was taken as the research background, and Petrel integrated geological engineering software was used to simulate the influence law of three fracturing locations of roof, roof + coal seam and coal seam on the production of coalbed methane wells. The results show that when the coal reservoir is 1 m and 5 m away from the high aquifer, the three fracturing methods show the characteristics of low gas production, high water production and late gas occurrence time. When the distance from the aquifer increases to 10 m and 15 m, the variation range of water and gas production is small. Under the influence of floor high water content, the cumulative gas production of the three fracturing locations is from large to small: roof > coal seam + roof > coal seam; the coal seam, in which the roof fracturing has high peak daily gas, short gas emergence time and low water production, is less affected by high aquifer, and is more suitable for the fracturing reconstruction of coal bed gas wells with high water content in the floor. Three kinds of fracturing positions have been verified in Hancheng Mining Area, and the research results can provide guidance for the selection of fracturing location of floor coal seam with high water content.
