沁南地区15~#煤压裂改造技术研究及应用

Qinnan Field 15~# CBM Fracturing Technology Research and Application

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。

15# coal seam is production replace capacity to 3# coal seam in Qinshui basin. In order to study fracturing technique of 15# coal seam in Qinshui basin, the geological feasibility of some pilot area is analyzed from such aspects as structure, stress,hydrological conditions, coal reservoir parameters and so on. On the basis of reservoir geology understandings, corresponding fracturing development plan is made and fracturing fluid system, proppant combination and fracturing operation parameters are formed, which are suitable for effect,which plays a significant basin. the pilot production area. The on-site application has achieved good role for future development of high-rank 15# coal seam in Qinshui
