多脉冲压裂用于低渗煤层开发可行性分析

Analysis about Feasibility of Multiple Pulses Loading Fracturing in Low Permeability Coal Reservoir

针对多脉冲压裂广泛地用于低渗煤层开发的趋势,从储层物性、煤岩力学性质、次级微裂缝、煤层气多重解吸作用、施工工艺成熟性、复合性和施工成本等7个方面,并结合沁水盆地3#煤层Z2-005井的压裂施工增产效果,分析了多脉冲压裂用于低渗煤层压裂开发的可行性。

Aimed at the tendency of the widely used of multiple pulses loading fracturing on the development in low permeability coal reservoir, the feasibility, which includes reservoir physical properties of 3# coal seam, the mechanical properties of coal, secondary micro-fractures, and multiple desorption effects of CBM, the ripeness of construction technology, compositionality, and the cost of construction technology, with the effect of production increasing of Z2-005 well in 3# coal seam of Qinshui basin, is analyzed.
