Abstract
The utility model belongs to oil well production parameter control device, the adjustable open flow device behind the vapour is annotated to concretely relates to viscous crude well. This oil well can be banished and spouted the device, it by rotatory stopper, sealing ring, flat housing, advance oil pipe, gland, sealing ring, rotary outer sleeve, overcoat, play oil pipe and constitute. The glib talker of different specifications is conveniently adjusted in the time of can realizing annotating the vapour open flow to the oil well to application through this the device, need not the closing well and removes stage makeup and costume, changes the glib talker, and production does not lead to the fact the influence to the oil well. The needs that vapour open flow process was annotated to the viscous crude oil well are satisfied in the transform adjustment of being convenient for of glib talker that the device has 6 specifications. The device has simple structure, and is easy and simple to handle, and laborsaving saving time is is easily popularized and applied in the production of viscous crude oil well.
Description
Technical field
This utility model belongs to oil well production parameter controller, is specifically related to the adjustable blow-out release device after a kind of heavy oil wells steam injection.
Background technology
In heavy oil wells steam injection production process, oil well open flow is an important step in production management.During oil well open flow, in order to adjust open flow parameter, need the oil nozzle changing in the resistance oil nozzle sleeve of different size.The process changing oil nozzle includes closing well, closes tubing valve, dismantles water jacket plug, the work such as oil nozzle of removing stage makeup and costume, and operation more bothers, and labor intensity is relatively big, and easily causes environmental pollution.
Summary of the invention
In order to overcome shortcoming present in prior art, the utility model proposes and a kind of be not required to the operations such as closing well and just can convert the device of oil nozzle bore in water jacket, this device is easy to operate, time saving and energy saving, work efficiency height.
This utility model is for reaching above-mentioned purpose, be the technical scheme is that a kind of adjustable blow-out release device of oil well (as shown in Figure 1), it is by rotating piston (1), sealing ring A(2), plane bearing (3), oil inlet pipe (4), gland (5), sealing ring B(6), rotary sleeve (7), overcoat (8), flowline (9) form.It is: according to job demand that the indoor design of rotating piston (1) (as shown in Figure 2) has the oilhole of the different bore in uniform 6 and a large through-hole, and rotating piston (1) rear end is designed for hexagon prism, is carved with relative oilhole diameter labelling below hexagon prism in place of its feature.Gear needed for selecting during operation, the hexagon prism on rotating piston (1) is rotated with spanner, rotating piston (1) is made to select the Plane Rotation of gear to flowline (9) side, the oilhole of rotating piston (1) communicates with the oil-out on rotary sleeve (7), i.e. completes oilhole bore operation in linear transformation water jacket.When oil well open flow needs to change different size oilhole bore, according to design oilhole size, hexagon prism knob to the required bore mark revolving rotating piston (1) with spanner can complete change.
This utility model need not closing well and removes stage makeup and costume, changes oil nozzle and carry out open flow when using.This device has simple in construction, easy and simple to handle, laborsaving saves time, it is easy to adjusts in producing well particularly working system and extensively applies than steam injection well open flow more frequently.

Detailed description of the invention
:
Oil inlet pipe of the present utility model (4), flowline (9) end are thimble connector, oil inlet pipe (4) clip produces gate with production tree and is connected, oil inlet pipe (4) leads to the oil-in of rotating piston (1), flowline (9) and well head single well pipeline pass through clamp connection, rotary sleeve (7) outer wall has 1 circular hole, circular hole 6 oilholes internal with rotating piston (1) cooperate, it is achieved regulate the function of the fluid flow size internal by this device.
6 oilhole bores of this utility model interchangeable, before open flow operation, first select suitable gear, then rotate rotating piston (1) to specifying oilhole mark position with spanner, it is achieved oilhole bore change operation in water jacket.After open flow, all rotate rotating piston (1) by preceding method and make its selected a certain oilhole alignment rotary sleeve (7) oil-out, oil well working system on request can be made to put into production.
Claims (2)
1. the adjustable blow-out release device of oil well being used for controlling and adjust production well proration, by rotating piston (1), sealing ring A(2), plane bearing (3), oil inlet pipe (4), gland (5), sealing ring B(6), rotary sleeve (7), overcoat (8), flowline (9) form, it is characterized in that: the indoor design of rotating piston (1) has the oilhole of the different bore in uniform 6 and a through hole, and described through hole communicates with oil inlet pipe (4)；Rotating piston (1) rear end is designed for hexagon prism, is carved with corresponding oilhole diameter labelling below hexagon prism；According to required gear, rotating rotating piston (1) and make its gear position indicia plane to flowline (9) side, i.e. upper with rotary sleeve (7) oil-out of the internal oilhole of rotating piston (1) communicates；Rotary sleeve (7) oil outlet communicates with overcoat (8) endoporus；Overcoat (8) endoporus communicates with flowline (9).
Oil well the most according to claim 1 is adjustable blow-out release device, is characterized in that, oil inlet pipe (4), flowline (9) use box cupling connected mode, are connected with production tree and flow line respectively.
