| Abstract:According to the difficulties of underground potash salt mining in Qinghai salt flats, the hydraulic fracturing technology was tried to use for increasing the single well yield. The paper introduces the hydraulic fracturing test about the technical principles, fracturing wells arrangement, determination of fracturing section and setting site, installation of ground equipments, fracturing operation and pumping test. The test results show that the stimulation effect is good with average increasing yield up to 559.25% for 4 wells. The hydraulic fracturing technology is introduced into the stimulation field of halogen salt mine in China for the first time, which fills a domestic gap in this field. |
