压裂液对煤储层伤害实验及应用--以沁水盆地西山区块为例
Experiment and application of fracturing fluid damage to coal reservoir：a case of Xishan block in Qinshui basin
摘要
Abstract
In order to analyse the fracturing fluid damage to the Xishan coal reservoir, used the working fluid evaluate methods was used, the effect of fracturing fluid, clay stabilizer and surfactant on coal reservoir was stud-ied. The results show that the active hydraulic fracturing fluid used in the field does harm to the coal reservoir, and the damage rate is 37.2%, the clean degree of fracturing fluid base has great influence on the degree of damage of coal seam, and the damage of theun filtered water is much bigger than that of the filtered water and well water, clay stabilizer KCl dosage should be determined according to the water-sensitive damage degree, the appropriate adding amount of clay stabilizer in the study area should be 2%~4%, in order to ensure that the fracturing fluid returns to the exhaust as soon as possible, the surface active agent should be added in the fracturing fluid, the amount, sur-factant should be better at 0.2%, the actual application can be adjusted, but not more than 1.4%.In the actual pro-duction of fracturing fluid is optimized by the method, the gas production of optimized fracturing fluid CBM wells is 300~500 m3 higher than that of not optimized gas wells.关键词
