往碳酸盐岩含水层中注入盐酸,扩大裂隙及溶隙,增加钻孔出水量的方法,早已受到重视,效果良好。但这类岩层的组成比较复杂,与酸反应后,往往还有一部分物质,如粘土、砂砾、岩渣、铁屑等残留下来,堵塞水流通道。此时将液态二氧化碳通入孔内,产生人工井喷,可将这些残留物喷出地 The injection of hydrochloric acid into aquifers of carbonate rocks to expand fissures and dissolve gaps and increase the amount of water outflow from boreholes has long been taken seriously and the effect is good. However, the composition of such rock formations is rather complicated. After reacting with acid, there are often some substances such as clay, gravel, rock residue and iron filings remaining to block the water flow channel. At this point the liquid carbon dioxide into the hole, resulting in artificial blowout, these residues can be ejected
