沁水盆地15~#煤层为3~#煤层产能接替煤层,为研究适合沁南地区15~#煤层的压裂工艺,以沁南某试采区为例,从构造、地应力、水文条件、煤储层参数等多方面分析了试采区地质条件的可行性。根据储层地质认识制定了配套的压裂开发工艺方案,形成了适用于试采区的压裂液体系、支撑剂组合、压裂施工参数,现场应用取得了一定的效果,对指导以后沁水盆地15~#高阶煤层的开发有重要意义。
In order to study the fracturing technology suitable for 15 # seam in Qinan area, taking the 15 # seam in Qinshui Basin as the succession seam of No. 3 coal seam, taking a certain pilot mining area in Qinnan as an example, from the aspects of tectonics, geostress, hydrological conditions, Coal reservoir parameters and other aspects of the feasibility analysis of the geological conditions of the trial mining area. Based on the understanding of reservoir geology, a complete set of fracturing development process was developed and fracturing fluid systems, proppant combinations and fracturing parameters suitable for the pilot mining area were formed, and the field application has achieved certain effects. After guiding the Qinshui The development of 15 ~ # high-grade coal seams in the basin is of great significance.
