Abstract
The utility model relates to the technical field of production and test of horizontal wells, in particular to a special two-pipe elevator. One end of a bearing active body is connected with a bearing body through a movable pin, and the other end is equipped with a switch handle and a plug-in type switch, and causes the bearing active body and the bearing body to be freely opened and closed through the switch handle and the plug-in type switch; a fixed handle is designed on the outer wall of the bearing active body; when the bearing active body and the bearing body are closed, small holes and large holes are formed between the bearing active body and the bearing body; and limiting holes are respectively designed at two ends of the bearing body. The elevator achieves the synchronous tripping operation of underground produced tubing and 2 inch integral joint tubing in two-pipe process adopting a horizontal well production and test technology, and overcomes the defects that a conventional elevator only can trip single tubing.
Description
Technical field:
The utility model relates to a kind of horizontal well production test technical field, particularly a kind of two-tube special-purpose elevator.
Background technology:
Horizontal well worldwide is widely applied day by day as a ripe applicable technology of oil-gas field development, belongs at home blank for the production performance evaluation measuring technology of horizontal well.The horizontal well production test realizes that by two-tube technique production system and test macro work alone separately, and realize that one of problem that the horizontal well production test need to solve is exactly the technology that removes of two-tube tubing string, it is single that yet existing elevator can only remove, rountrip when can not realize downhole production oil pipe and 2 inches nothing joint hoop oil pipes.
The utility model content:
The technical problems to be solved in the utility model is to provide a kind of two-tube special-purpose elevator, and this device has realized that in the two-tube technique of horizontal well production test technology downhole production oil pipe and 2 inches are without rountrip in joint hoop oil pipe.Overcome existing elevator and can only remove single deficiency.
Technical solution adopted in the utility model is: a kind of two-tube special-purpose elevator comprises the carrying body and carries mobile; Carrying mobile one end is connected with the carrying body by removable pin, the other end is installed switch handle and plug-in switch and is made carrying mobile and carry between body can free open and close by switch handle and plug-in switch, be designed with fixed handle on carrying mobile outer wall, when carrying mobile is closed with the carrying body, carrying mobile can form aperture and macropore with carrying between body, carries body two ends and is designed with respectively spacing hole.
The beneficial effects of the utility model are: the utility model has been owing to having adopted carrying body and the carrying mobile can free open and close and the mode of between design macropore and aperture, thereby has downhole production oil pipe and 2 inches functions without rountrip in joint hoop oil pipe in the two-tube technique of horizontal well production test technology.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
The specific embodiment:
As shown in Figure 1 and Figure 2, a kind of two-tube special-purpose elevator comprises carrying body 1 and carries mobile 6; Carrying mobile 6 one ends are connected with carrying body 1 by removable pin 9, the other end is installed switch handle 2 and plug-in switch 4 and is made carrying mobile 6 and carry between body 1 can free open and close by switch handle 2 and plug-in switch 4, be designed with fixed handle 5 on carrying mobile 6 outer walls, when carrying mobile 6 is closed with carrying body 1, carrying mobile 6 can form aperture 7 and macropore 8 with carrying between body 1, carries body 1 two ends and is designed with respectively spacing hole 3.
During site operation, external force outwards puts on switch handle 2 and fixed handle 5 simultaneously, switch handle 2 is sent to external force on plug-in switch 4, spacing sliding function by removable pin 9, to carry mobile 6 opens, form certain space with carrying body 1, downhole production oil pipe and 2 inches nothing joint hoop oil pipes are respectively charged in macropore 8 and aperture 7, external force inwardly puts on the closed mobile 6 of carrying on switch handle 2 and fixed handle 5 simultaneously, production tube and 2 inches nothing joint hoop oil pipe independent suspensions under completed well; With the elevator opening part of packing into of the suspension ring on the workover rig hook, the suspension ring safety pin inserts in spacing hole 3, utilizes workover rig power to complete two-tube rountrip.
Be understandable that, above about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
