In order to overcome the disadvantages of brine development by aqui-soluble through a single well in the rock salt,the controlled directional drilling down -hole motor is employed to make a pair of me-dium-radius of curvature ,highly inclined directional wells intersected with each other in the subsurface salt forma-tion,realizing brine developed by the intersected wells .Therefore ,description :Emphasized on the new drilling tech-nique,testing and study results of the intersected wells.
