Abstract
The utility model relates to an oil well drilling and production technology field especially relates to a circulating valve, its characterized in that: including top connection, shear pin, nut, rupture disk, urceolus, piston cylinder, lower clutch, have the liquid hole in the top connection, the lower part of top connection is passed through the shear pin with the piston cylinder is connected, outer barrel casing is in the piston cylinder outer and with the top connection is connected, the rupture disk passes through the nut is installed on the round hole on the urceolus, the piston cylinder with be formed with the piston chamber between the urceolus, the round hole with piston chamber intercommunication, the lower clutch with urceolus threaded connection. This device easy operation, the application of rupture disk can make when needing inside and outside switch -on, and annulus pressure is controllable. Easy operation can use repeatedly.
Description
Technical field
This utility model is related to oilfield drilling and production technology field, more particularly to a kind of circulating valve.
Background technology
Oil well casing causes sleeve pipe leakage phenomena occur because of reasons such as cementing quality, connection screw thread, ground movement, corrosions,
Oil supply well measure construction brings unfavorable factor and affects crude output.Once leakage situation occurs in the non-payzone of oil well, implementing to repair
Leakage points are must determine before multiple, the method for now verifying casing leakage point typically adopts packer, in payzone with upper bit closing oil
Set annular space, is verified by sleeve pipe pressuring method to sleeve pipe.In prior art, the valve on packer is applied all to be belonging to
Check valve, it is impossible to which enough repetitive cyclings are used, and cause cost to increase.
Utility model content
The purpose of this utility model is to overcome the shortcomings of above-mentioned technology, and provides a kind of circulating valve, simple structure, cost
It is low, can reuse.
This utility model for achieving the above object, is employed the following technical solutions：A kind of circulating valve, it is characterised in that：Including
Top connection, shear pin, nut, rupture disk, outer tube, piston cylinder, lower contact；Liquid pass hole, the top connection are carried in the top connection
Bottom be connected with the piston cylinder by the shear pin, the outer sleeve is outer in the piston cylinder and connects with the top connection
Connect, the rupture disk is arranged on the circular hole on the outer tube by the nut, shape between the piston cylinder and the outer tube
Into there is plunger shaft, the circular hole is connected with the plunger shaft, and the lower contact is threadedly coupled with the outer tube.
The beneficial effects of the utility model are:Relative to prior art, this device is simple to operate, and the application of rupture disk can
During so as to need inside and outside connection, annular pressure is controllable.It is simple to operate, can be with Reusability.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of this utility model steering state.
Specific embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describes specific embodiment of the present utility model in detail.Such as Fig. 1 and Fig. 2 institutes
Show, a kind of circulating valve, including top connection 1, shear pin 2, nut 3, rupture disk 4, outer tube 5, piston cylinder 6, lower contact 7；Connect on described
Liquid pass hole 8 is carried on head, the bottom of the top connection is connected by the shear pin with the piston cylinder, and the outer sleeve is described
Piston cylinder is outer and is connected with the top connection, and the rupture disk is arranged on the circular hole on the outer tube by the nut, institute
State and plunger shaft 9 be formed between piston cylinder and the outer tube, the circular hole is connected with the plunger shaft, the lower contact with it is described
Outer tube is threadedly coupled.Throwing instrument is lowered into precalculated position, and annular space is suppressed, and rupture disk 4 ruptures, and liquid-driving piston cylinder 6 is moved down, and is cut
Disconnected shear pin 2. forms inside and outside connection when the hole in top connection 1 spills.
Relative to prior art, this device is simple to operate, the application of rupture disk, when can make to be connected inside and outside needs, annular space
Pressure controllable.It is simple to operate, can be with Reusability.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
