Construction Technology of Directional Branch Hole in Complex Easily Inclined Stratigraphic
Abstract:The construction of directional branch hole in steep orebody can not only save drilling workload, reduce drilling rig relocation and road repairing, but also is helpful for environmental protection and improving geological prospecting effect. This paper introduces the technology and processes of directional branch hole with LZ continuous whipstock in complex easily inclined stratigraphic.
