Abstract
The utility model relates to an aggravating ball sand preventing device, which is suitable for petroleum pumping well. The structure of the aggravating ball sand preventing device is that an outer pipe is provided with a lower connector of an oil distribution and sand desilting device and an upper connected of oil outlet after desilting. The lower connector is connected with the lower portion of an oil distribution desilting core pipe, and the upper portion of the oil distribution desilting core pipe is connected with a fixed valve cap. By means of the structure, the aggravating ball sand preventing device achieves the purpose of completing desilting automatically during oil pumping and can improve working conditions of an oil well pump while preventing sand, improve pumping efficiency of the oil well pump, increase oil gas yield, and prolong service life of the oil well pump.
Description
Technical field
The utility model relates to a kind of sand control device, relates in particular to a kind of Heavy ball sand control device, is applicable to the oil pumpingh well.
Background technology
At present, pumpingh well in process of production, impurities of crude oil be prone to get into pump barrel, often causes the oil well pump holddown.In addition, in the prior art, when fixing ball valve was closed, the irregular movement meeting of valve ball caused the ball valve shut-in time long, and leakage rate is big.And the oil well that viscosity of crude is big is prone to exist valve to close problems such as slow or not tight.
Summary of the invention
The utility model provides a kind of Heavy ball sand control device to the problem that exists in the above-mentioned prior art, has solved to be prone in the prior art that holddown, leakage rate are big, valve is closed slow or not tight problem, and has increased oil and gas production, has improved production efficiency.
The technical scheme of the utility model is following:
Outer tube (2) is provided with fuel-displaced top connection (1) behind lower contact (10) and the desilting of the oily desilting device of branch; Lower contact (10) links to each other with the bottom of dividing oily desilting core pipe (9), divides the top of oily desilting core pipe (9) to link to each other with standing valve cap (6).
Standing valve seat (8), valve ball (7) be housed in the described standing valve cap, increase the weight of valve body (4), guide strip (5) and guide strip gland (3); Standing valve seat (8) is fixedly connected with screw thread through core pipe (9) and standing valve cap (6); Valve ball (7) is connected as a single entity and in guide strip (5), moves up and down with increasing the weight of valve body (4), and guide strip (5) is fixedly connected with screw thread through guide strip gland (3) and standing valve cap (6).
The operating principle and the advantageous effect of the utility model are following:
1, passes through said structure; Pumpingh well crude oil suction in process of production is introduced into flow velocity is reduced; In the sand control chamber, form an infall process; Make that suspension can be deposited in the sand control chamber smoothly in the crude oil, cry out the impurity of few entering pump barrel, better action is arranged preventing the oil well pump holddown.
When 2, Heavy ball standing valve and standing valve cap had overcome the ordinary fixed ball valve and close, the irregular movement of valve ball caused the ball valve shut-in time long, the defective that leakage rate is big; The Heavy ball standing valve in the standing valve cap along the straight line bob; Be a kind of limit-type valve, controlled beating of standing valve, accelerate to close; Increase degree of filling, improved pump efficiency.
3, in oil pumping process, Heavy ball sand control valve forms the protection of two valves with the oil well pump standing valve, has solved the valve that the big oil well of viscosity of crude is prone to exist more effectively and has closed problems such as slow or not tight.
4, the scene builds the pressure, voltage regulation result is fabulous, has reduced the oil pumping pump leakage effectively.
5, simple in structure, it is convenient to install, and should not damage, just reusable through simple cleaning at the scene.Be installed in the working condition that to improve oil well pump under the oil-well pump of oil well, improve the pump efficiency of oil well pump, increase oil and gas production, prolong the application life of oil well pump.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, top connection, 2, outer tube, 3, the guide strip gland, 4, increase the weight of the valve body, 5, guide strip, 6, the standing valve cap, 7, valve ball, 8, the standing valve seat, 9, divide oily desilting core pipe, 10, lower contact.
The specific embodiment
The utility model, is described in detail as follows in conjunction with specific embodiment with reference to accompanying drawing.
Embodiment
Fuel-displaced top connection 1 behind the lower contact 10 that outer tube 2 is provided with the oily desilting device of branch and the desilting; Lower contact 10 links to each other through screw thread with minute bottom of oily desilting core pipe 9, and the top of dividing oily desilting core pipe 9 and standing valve cap 6 link to each other through screw thread.Standing valve seat 8, valve ball 7 be housed in the described standing valve cap, increase the weight of valve body 4, guide strip 5 and guide strip gland 3; Standing valve seat 8 is fixedly connected through core pipe 9 and standing valve cap 6 usefulness screw threads; Valve ball 7 is connected as a single entity and in guide strip 5, moves up and down with increasing the weight of valve body 4, and guide strip 5 is fixedly connected through guide strip gland 3 and standing valve cap 6 usefulness screw threads.
Top connection on the outer tube and oil well pump link fuel-displaced, and the lower contact on the outer tube is used for oil-feed and the oily desilting device of fixing branch.Oil is through minute oily desilting device core pipe and increase the weight of valve body entering standing valve cap, and the branch hydraulic fluid port on the standing valve cap slows down and turns to the desilting process of accomplishing.
Technical data: length overall: 830 millimeters; Maximum gauge: 90 millimeters; Operating pressure: 20MPA; Operating temperature: 90 ℃; Two ends connect button-type: (pin thread is last) 27/8TBG.
The protection domain of the utility model does not receive the restriction of specific embodiment, is as the criterion with claim.
