Abstract
The utility model discloses a multifunctional workover blowout preventer, comprising a shell with a central hole. The upper end of the central hole can be removable and is connected with a tubing hanger and a tubing short-connection is provided inside the tubing hanger cavity. With the structure, after workover operation is completed, the multifunctional workover blowout preventer is not dismantled, but only the self-sealing head is replaced by the tubing hanger, and thus the utility model is conveniently operated and saves time and labour, thereby reducing the occurrence rate of accidents and improving working efficiency and reducing the cost.
Description
Technical field
Used multi-functional well workover preventer when the utility model relates to underground work on a kind of oil field.
Background technology
At present, band from the multi-functional well workover preventer of end socket when carrying out workover treatment, need pull down and refill the multi-functional well workover preventer of band on the well head behind the tubing head from end socket, pull down the multi-functional well workover preventer of band again after repairing completion from end socket, load onto tubing head, so operation is wasted time and energy and is easily leaked, and causes the accident.
The utility model content
The purpose of this utility model is to provide a kind of and need not to dismantle, time saving and energy saving, multi-functional well workover preventer that accident rate is low.
For achieving the above object, technical solution of the present utility model is:
A kind of multi-functional well workover preventer comprises housing, and housing is provided with mesopore, and described mesopore upper end is removably connected with tubing hanger, is provided with the oil pipe short circuit in the tubing hanger chamber.
Further, be provided with sealing device between described tubing hanger and the housing.
Further, described housing sidewall is provided with opening, and this opening part is provided with sleeve valve.
After adopting said structure, finish in workover treatment, multi-functional well workover preventer need not dismounting, only needs and will be changed to tubing hanger self-styled first watch, and is easy to operate, time saving and energy saving, reduced accident rate, and can increase work efficiency, reduce cost.
