摘要
青海一里坪盐湖赋存丰富的液体锂矿(晶间卤水),但传统井采方式的卤水产量严重依赖于随机性很大的地层性质.通过对井壁附近的地层进行冲击波致裂,可以使岩土层裂隙增多,从而加速渗流而提高产量.针对本次试验的地层,12次的冲击次数相对而言比较安全.相关技术成果对卤水和石油开采等液体采矿行业有很好的参考价值.
Abstract
There are abundant liquid lithium deposits(intercrystalline brine)in Yiliping Salt Lake,Qing-hai Province.However,the brine yield of traditional extraction well depends heavily on the formation prop-erties of which the randomness is very high.By cracking the strata near the shaft wall with shock wave cracking technique,the fracture of rock and soil layer can be increased,so as to achieve the industrial pur-pose of accelerating the seepage and increasing the production.For the geo-layer in this test,the number of 12 shocks is relatively safe.The relevant technological achievements have good reference value for liquid mining industries such as brine and petroleum mining.
