Abstract
The utility model provides a ground water distributor and belongs to a device used for water injection well in the oil field. The utility model has water distributor body, a gland is fixed on the lateral side of the water distributor body, a pressure cap is arranged on the external surface of the gland, a valve rod gets through the gland and the pressure cap and the end of the valve rod has a valve ball which is arranged in a valve chamber on the water distributor body, a water nozzle is arranged in the water distributor body, the internal cavity of the water nozzle is communicted with the valve chamber, and a water nozzle pressure cap is arranged on the external surface of the water nozzle. When need to use the ground water distributor, the diameter of the internal cavity of the water nozzle can be calculated according to needed water injection rate every day, and then the water nozzle can be used to control water injection rate. The utility model has accurate control on water injection rate, simple structure, easy usage and low cost while reducing production cost.
Description
Technical field
The utility model relates to a kind of device that is used for water injection well in oil fields, especially a kind of injection well downhole flow regulator.
Background technology
At present, the control mode to the water injection rate of water injection well mainly contains Artificial Control and high pressure valve control.Artificial Control is difficult to accurately control water injection rate fully by rule of thumb.During high pressure valve control, because hydraulic pressure is higher, the impact force that water under high pressure produces can very fast bad valve of thorn.And because the water of being annotated is the sewage that contains impurity, corrosivity is strong, influences the application life and the seal degree of high pressure valve.Seal degree just is difficult to accurately control water injection rate after reducing.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of ground injection well downhole flow regulator is provided, and it can accurately control water injection rate.
The utility model is to realize like this, the ground injection well downhole flow regulator, it has the injection well downhole flow regulator body, injection well downhole flow regulator body side is fixed with gland, the gland outside is equipped with pressure cap, the valve stem end of passing gland, pressure cap has valve ball to be positioned at valve chamber on the injection well downhole flow regulator body, is installed in the intrinsic water nozzle inner chamber of injection well downhole flow regulator and communicates with valve chamber, and there is the water nozzle pressure cap water nozzle outside.
Adopt the ground injection well downhole flow regulator of said structure, during use, converse the intracavity diameter of used water nozzle according to the water yield that will inject every day, with this water nozzle water injection rate is controlled then and got final product, accurate to the control of water injection rate, simple in structure, easy to use, cheap, reduced cost of production.Used water nozzle can be ceramic materials, and is corrosion-resistant, long service life.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and using method.
As shown in drawings, the ground injection well downhole flow regulator of the utility model, it has injection well downhole flow regulator body (9), injection well downhole flow regulator body side is fixed with gland (3), the gland outside is equipped with pressure cap (2), valve rod (1) end that passes gland, pressure cap has valve ball (4) to be positioned at valve chamber on the injection well downhole flow regulator body, is installed in the intrinsic water nozzle of injection well downhole flow regulator (6) inner chamber and communicates with valve chamber, and there is water nozzle pressure cap (7) the water nozzle outside.
Described water nozzle (6) is made by ceramic materials.
Sealing ring (5) can be installed between water nozzle and injection well downhole flow regulator body
During use, converse the intracavity diameter of used water nozzle earlier according to the water yield that will inject every day, then, this water nozzle is installed in the injection well downhole flow regulator body.When needing water filling, rotation valve rod moves valve ball outward, and water will flow to the filling pipe that is connected with the utility model through injection well downhole flow regulator chamber body, valve chamber, water nozzle inner chamber etc., flows in the water injection well at last.
By the control valve device that gland, pressure cap, valve rod, valve ball etc. constitute, can arrange 3 at the circumferentially even of injection well downhole flow regulator body.The valve chamber of each control valve device communicates with the inner chamber of a water nozzle respectively.During use, can use one of them water nozzle that the water injection rate of a water injection well is controlled separately.Each water nozzle inner chamber is linked to each other with the filling pipe of three water injection wells respectively, simultaneously the water injection rate of three water injection wells is controlled.
Connect body (8) on the injection well downhole flow regulator body in addition, this connection body can be made one with the injection well downhole flow regulator body, also can be installed together by screw thread, its concrete structure so that water nozzle is installed, the water nozzle pressure cap is advisable.
Claims (2)
1. ground injection well downhole flow regulator, it is characterized in that, it has injection well downhole flow regulator body (9), injection well downhole flow regulator body side is fixed with gland (3), the gland outside is equipped with pressure cap (2), valve rod (1) end that passes gland, pressure cap has valve ball (4) to be positioned at valve chamber on the injection well downhole flow regulator body, is installed in the intrinsic water nozzle of injection well downhole flow regulator (6) inner chamber and communicates with valve chamber, and there is water nozzle pressure cap (7) the water nozzle outside.
2. ground as claimed in claim 1 injection well downhole flow regulator is characterized in that, described water nozzle (6) is made by ceramic materials.
