Wall hook type tail pipe hanging device for lateral well

2005 
The utility model relates to a wall-hook type tail pipe hanging device used in well drilling and well completion techniques of branch wells, which mainly solves the defect that a tail pipe hanging device used in the existing well completion technique of the branch wells can not easily realize the transfixion of main and branch well holes. The utility model is characterized in that the middle part of a hanging device main body (2) is provided with a pre-opening window (3), a hanging hook (4) is fixed to the lower end of the pre-opening window (3) in a jointing mode, and a positioning sleeve (5) is fixed between the hanging device main body (2) and a lower end sleeve pipe buckle (6) in a jointing mode. The utility model has the characteristic that the transfixion of the main and the branch well holes can be successfully realized, and the operation of entering a lateral branch can be realized through being lowered a special guiding tool.
