In order to explore and optimize the route and parameters of brine extraction technology, we carried out a verification brine well group by using exploratory well. In the process of the implementation of this well group, precise orientation technology is successfully introduced based on conventional orientation technology, the well group docking success only once which avoids groove construction work and the treatment of large amounts of dilute brine by using conventional orientation technology only. In the test run of the well group, the brine extraction flow is about 75-100 m 3 and the concentration of brine is about 290-310 g/L. /h, The implementation condition and test run of brine extraction show that the use of precision orientation technology is advan
