摘　　要：研究了不同类型压裂液体系对煤岩吸附规律的影响,结果表明,泡沫压裂液具有较低吸附伤害性,失水性较好,加上压裂过程煤粉的作用,泡沫压裂液能够起到很好的降滤失作用,具有良好的携砂性能,且具有良好稳定性。沁水盆地5口井的现场施工试验表明,该泡沫压裂液具有见气快、见气率高等特点,能够很好满足煤层气井压裂增产的需要。The influence of different types of fracturing fluids on coal adsorption damage were studied. The results show that the foam fracturing fluid has low adsorption damage. The foam fracturing fluid has low filtration loss and braise generated during fracturing can reduce the filtration loss. And the foam fracturing fluid has strong proppant carrying capacity and excellent shearing bearing ability. Stimulation treatments were conducted in Qinshui basin five wells,the foam fracturing fluid has short gas breakthrough time,high rate of breakthrough and can satisfy the requirements of CBM stimulation treatments.
