摘　　要：罗布泊盐湖区的W_(2)~W_(4)承压卤水矿层存在孔隙率低、富水性差等问题,造成采卤井的出卤量小。通过空气驱动技术于罗北凹地1~15采卤井处进行空气驱动试验,分别在输压注气前后进行同降深的抽水试验。注气过程中,注入的高压空气在1~15采卤井与气驱辅助孔之间形成运移通道,能够在一定程度上改善气驱辅助孔周边弱结构地层的连通性。根据试验结果,提出相关工艺参数的优化措施,为增大罗布泊盐湖区单井出卤量提供了工程化应用依据。The W_(2)~W_(4) pressurized brine layers in the Lop Nur Salt Lake area have problems such as low porosity and poor water yield,resulting in low brine production from brine wells.Air-driven technology is carried out at 1~15 brine well in Luobei mining area by air-driven technology,then pumping tests are carried out at the same drawdown before and after gas injection.In the process of gas injection,the injected high pressure air forms a migration channel between 1~15 brine well and the gas drive auxiliary hole,which has a certain improvement effect on the connectivity of the weak structure strata around the gas drive auxiliary hole.Based on the experimental results,the optimization measures for relevant process parameters are proposed,providing an engineering application basis for increasing inflow of brine wells in the Lop Nur salt lake area.
