Abstract
The utility model relates to a constant flow clogging device of a water injection well, which is composed of a salvaging positioning device, a metered flow device and a throttling constant pressure device, and is used for the water supply of the water injection well with constant flow and constant quantity. Because the constant flow clogging device is provided with the metered flow device and the throttling constant pressure device, the high pressure water can be changed into the pressure stabilizing water to inject the ground when the water supply operation is conducted. The metered flow is conducted according to the sizes of the ground pressure, and the sizes of a throttling opening can be adjusted automatically according to the change of the water supply pressure. The constant water supply is ensured, the efficiency that the oil is expelled by the water is displayed in best degree, and the recovery efficiency of the crude oil is enhanced. Large numbers of manpower and material resources are saved.
Description
The utility model belongs to the design and the manufacturing technology field of the constant flow blanking plug on the flushing equipment.
Being used for oil producing operation flushing equipment at present both at home and abroad mainly is 665-2 type eccentric injection mandrel, is differential pressure type, and it is to realize by an annular cylinder to underground water-injection.Actual water supply do not have regulatory function voluntarily, so can not guarantee the constant current water distribution owing to the variation that is subjected to strata pressure and pressure of supply water changes.The water that also need be equipped with a large amount of various different sizes is chewed in addition, and must hundreds of rice to the dark oil well of several kms up and down repeatedly debugging could select a required specification water to chew, special trouble.Main is can not guarantee constant water supply and influence recovery ratio, does not reach " water drive oil " effect.
The purpose of this utility model provides a kind of easy to operate and can guarantee the water injection well constant flow blanking plug that constant supplies water.To guarantee under the situation of strata pressure and pressure of supply water fluctuation to the water distribution of oil well Different Strata constant.
Structure of the present utility model is as shown in drawings: by salvaging positioner, setting flow apparatus and the throttling constant-voltage equipment constitutes.Its positioner is that a gland is arranged on positioning seat, has fishing rod on the gland.Setting flow apparatus is to have one to set bar in setting body inside.Its throttling constant-voltage equipment is that a guiding valve is arranged in the middle of control agent, and throttling constant voltage chamber is arranged in the middle of the guiding valve.The rear portion in chamber has spring base.In control agent one side pressure equalisation passage is arranged.Control agent front portion on the throttling constant-voltage equipment combines with the front stream oriented device by screw thread, thereby constitutes the utility model.The using method of this product is: at first need on the ground to calculate water distribution quantity according to the pressure gauge of interval differently, configure the flow of water, the setting bar that is about to set on the body is screwed to the relevant position, promptly reserves the delivery port size.Then fishing rod is fixed on the existing general fishing tool, puts into the down-hole and can use.In a bite water injection well, can drop into several constant flow blanking plugs according to interval demand differently, to satisfy the differently expelling water needs of interval of a bite water injection well.Its operating principle is: the water under high pressure (P of injection
1), enter the throttling constant-voltage equipment by water inlet after, become voltage stabilizing water (P through automatic voltage regulation
2), the setting flow apparatus delivery port of flowing through under the effect of pressure equalisation passage and spring then enters the stratum.When water injection well stops water filling or strata pressure greater than feed pressure, at this moment the water annotated appear by the outlet phenomenon of backflowing, and the water that backflows so just promotes guiding valve and draws back, and closes water inlet, plays the effect of check.Prevent that the impurity in the stratum from entering in the throttling constant voltage chamber.When water filling again, water under high pressure enters spring cavity and pressure equalisation passage by the guiding valve side, promotes to move on the guiding valve to open water inlet, to recover normal water supply.
The utility model is simple in structure, and is reasonable in design, easy to use.Need only base area stressor layer actual conditions configure the delivery port size, can drop into the down-hole uses, and can regulate discharge automatically, it can be supplied water under the constant current situation, improve " water drive oil " efficient, guarantee ordinary production, improve recovery ratio, water injection well management is easier, need not manually frequently handle valve and adjust the water yield.It is a kind of comparatively desirable water filling accessory.

The utility model is a metal system, and salvaging positioner wherein is existing general part.Revolving in fact can be with reference to this manual and accompanying drawing, and the known technology processing assembling of pressing metal processing specialty gets final product.
Below in conjunction with accompanying drawing the utility model is described further
The utility model constitutes by salvaging positioner, setting flow apparatus and throttling constant-voltage equipment.The structure of this three part is respectively: a gland (2) is arranged on positioning seat (3), have fishing rod (1) on the gland.The fishing rod rear portion is combined by screw thread and gland, and gland combines with positioning seat by the screw thread at rear portion again, salvages positioner thereby constitute.Setting flow apparatus is to have one to set bar (4) in setting body (5) inside, and the front end of setting body is combined by screw thread and positioning seat.Set bar and be similar to tap, its rear portion is threaded, and the internal thread through setting the body front portion combines.Turn the setting bar, move up and down the size of adjusting the setting delivery port with setting bar.The throttling constant-voltage equipment is that a guiding valve (8) is arranged in the middle of control agent (6), has throttling constant voltage chamber, guiding valve one side to have one to regulate restriction (11) in the middle of the guiding valve, at the control agent rear portion one spring cavity is arranged, and spring (9) is arranged in the chamber.There is a spring base (10) at the rear portion in chamber.One pressure equalisation passage (7) is arranged in control agent one side.The import of passage is connected with control agent inner spring chamber.Outlet is connected with the blanking plug delivery port.The control agent front portion combines with the front stream oriented device by screw thread.
Claims (1)
- The water injection well constant flow blanking plug, constitute by salvaging positioner, setting flow apparatus and throttling constant-voltage equipment, it is characterized in that the structure of setting flow apparatus is: setting has one to set bar (4) in the body (5), the structure of throttling constant-voltage equipment is: a guiding valve (8) is arranged in the middle of control agent (6), guiding valve one side has one to regulate a mouthful head piece (11), at the control agent rear portion one spring cavity is arranged, spring (9) is arranged in the chamber, there is a spring base (10) at the rear portion of spring cavity, and a pressure equalisation passage (7) is arranged in control agent one side.
