Is characterized in that: at least one end of the outer wall of the valve body of the oil pipe plug valve is a regular octagonal cylinder, the quick-assembling wrench mainly comprises a body, a torsion bar and a pin shaft, the center of the body is provided with a hole, the cross section of the hole is a regular octagon, a handle fixing seat is fixed on the outer wall of the body, and the torsion bar is fixed on the handle fixing seat through the pin shaft. The effect is as follows: the device is used for the downhole operation of the petroleum industry, and can be quickly installed on an operation pipe column to control the water hole in the pipe column and prevent formation fluid from being sprayed upwards when overflow and well kick occur in the process of pulling out and running down the pipe column.
Description
Technical field
The utility model relates to the oil field flow string, particularly in playing the lower tubular column process, when " overflow ", " well kick " take place, the oil pipe plug valve is installed, i.e. the two-way dual-purpose oil pipe plug valve of ready-package rapidly.
Background technology
At present, plug valve is widely used in petroleum industry drilling well, underground work, when " overflow ", " well kick " take place, is used for controlling rapidly hydrophthalmia in the tubing string, prevents upwards ejection of formation fluid, prevents from not have the generation of control " blowout " accident.As the Chinese patent notification number: 2707935, a kind of " two-way dual-purpose oil pipe plug valve " disclosed.But well head has greasy dirt, skids easily during operating personnel are hand held, is not easy to rotate to link on the interior tubing string of well to connect.Existing plug valve when in case of emergency robbing dress, has often been incured loss through delay and has been robbed ETL estimated time of loading, even the generation blowout causes the accident.Therefore, existing plug valve can not satisfy the needs of on-the-spot urgent Fast Installation.
The utility model content
The purpose of this utility model is: provide a kind of ready-package two-way dual-purpose oil pipe plug valve, satisfied scene in emergency circumstances connects the oil pipe plug valve, and two-way dual-purpose oil pipe plug valve is installed quickly and easily.Overcome existing plug valve, in case of emergency can not satisfy on-the-spot urgent Fast Installation, incured loss through delay and robbed ETL estimated time of loading, the deficiency that blowout causes the accident takes place.
The technical solution adopted in the utility model is: the two-way dual-purpose oil pipe plug valve of ready-package, form by oil pipe plug valve and fast-assembling spanner, the oil pipe plug valve is made of valve body, spool and packing, it is characterized in that: at least one end of the valve outer wall of oil pipe plug valve is the octagon cylinder, is commonly called as: " from all directions outer ".The fast-assembling spanner is mainly to be made up of body, torque arm and bearing pin.Body is the cylinder bodily form, and is porose at the body center, and the cross section in hole is an octagon, and the octagon cylinder of Kong Nengyu oil pipe plug valve outer wall cooperates.Be fixed with the handle holder on the outer wall of body, have groove on the handle holder, the inboard crosswise fixed of the groove on the handle holder has a bearing pin.Torque arm is cylindrical, and torque arm one end has pin shaft hole, and torque arm is connected on the bearing pin by pin shaft hole.Torque arm can rotate along bearing pin.
For the fast-assembling spanner can be fixed on the octagon cylinder of oil pipe plug valve outer wall, on the octagon cylinder of oil pipe plug valve outer wall, the located lateral groove is arranged; Be fixed with location key seat on the body outer wall of fast-assembling spanner, location key seat is the cylinder bodily form, on location key seat and body dowel hole is arranged, and positioning pin rod and spring are arranged in the dowel hole.The end of positioning pin rod stretch into the octagon center of body porose in, can stretch in the locating slot of oil pipe plug valve.
The locating slot of described oil pipe plug valve has two, and the position of two locating slots is symmetrical.
The operating process of the two-way dual-purpose oil pipe plug valve of ready-package: consult Fig. 1.
When first oil pipe of well head is heavy wall tubing, need to connect with cock upset end joint, quick-mounting device is installed on plug valve flat end.
When first oil pipe of well head is plain end oil well pipe, need to connect with cock flat end joint, quick-mounting device is installed on the plug valve upset end.
When normally removing oil pipe, earlier fast-assembling spanner 2 is installed on the oil pipe plug valve 1, standby with positioning pin rod 2.7 lockings.In playing the lower tubular column process, take place " overflow " or " well kick ", the torque arm 2.1 of fast-assembling spanner 2 is evened up a left side to be pushed away, make it slide into the operating position along bearing pin 2.2, both hands are mentioned torque arm 2.1 and oil pipe plug valve 1 then, aim at well head tubing coupling top, push-jump in the direction of the clock torque arm 2.1 and oil pipe plug valve 1 manually tighten after putting in place.Pulling positioning pin rod 2.7 unlocks and takes off fast-assembling spanner 2.Bite " from all directions outer " plane on the oil pipe plug valve 1 with pipe wrench, screw screw thread, close oil pipe plug valve 1 with special spanner, can control hydrophthalmia in the tubing string, prevent upwards ejection of formation fluid, " blowout " accident that prevents takes place.
The beneficial effects of the utility model: the two-way dual-purpose oil pipe plug valve of the utility model ready-package, can make oil pipe plug valve Fast Installation, convenient, practical, satisfied the needs of robbing the dress plug valve when finding overflow fast.Skidding when portable torque arm has profit to cause hand to embrace the oil pipe plug valve in the time of can preventing the well head overflow." from all directions outer " plane that processes on the oil pipe plug valve body can be used as the pipe wrench occlusal surface of oil pipe plug valve when linking closely, and pipe wrench skids when having avoided last button, has also avoided the bite possibility at oil pipe cock valve switching place of maloperation pipe wrench.Realized rapidly, prevented quickly that " blowout " accident from taking place.
