Abstract
The invention refers to an anti-sand device used for an oilfield well. Especially, the invention relates to a novel anti-settling sand stuck pump device, wherein the technical scheme of the novel anti-settling sand stuck pump device is that: the device consists of a taper body, a taper base, a valve body, a fixing base, a valve ball and a joint; one end of the fixing base is connected with the joint, and the other end of the fixing base is connected with the taper base by screw thread; the valve body is fixed at the inner part of the taper base, the valve ball is arranged in the valve body; the valve body is vertically provided with a liquid through hole. The novel anti-settling sand stuck pump device has the following beneficial effects: the novel anti-settling sand stuck pump device is reasonable in structural design and good in anti-sand effect; the problem that the grit enters the pump along with the output liquid is effectively solved; the stuck pump is prevented; the device can be freely lifted up and down along with a sucker rod; so that the other work cannot be affected, and any other additional work load cannot be taken to the work.
Description
Technical field
The present invention relates to a kind of oil field well and use sand control installation, particularly a kind of novel anti-sand setting holddown device.
Background technique
In oilfield process because many oil wells all shake out, the crude oil that promptly utilizes the oil well pump extraction all in various degree contain sand; Grit gets in the pump with output liquid, because the proportion of sand is bigger, constantly sinks at the oil recovery process medium sand; Increased the wearing and tearing of pump, more serious is when stop pumping for various reasons, forms the pump leakage owing to the sinking meeting of sand causes accident or the valve of sand holddown to fit badly pump seizure; In order to solve the oil well pump wear problem; Relevant technologies personnel once were designed with the several anti sand pump, though these schemes have solved some problems to a certain extent, because this problem of wearing and tearing of the pump that the sand that contains in the crude oil sinks to causing fails thoroughly to solve all the time; Particularly the problem of sand setting holddown more can't solve, and influences field produces.
Summary of the invention
The object of the invention is exactly the above-mentioned defective that exists to existing technology, and a kind of novel anti-sand setting holddown device is provided, reasonable in design, and sand controlling result is good, effectively solves grit and gets in the pump with output liquid, prevents holddown.
Its technological scheme is: mainly be made up of cone, awl seat, valve body, fixed base, valve ball, joint; One end jointing of fixed base, the other end of fixed base and awl seat are through being threaded an awl seat internal fixation valve body; Be provided with valve ball in the described valve body, valve body is equipped with liquid-through hole up and down.
The invention has the beneficial effects as follows: reasonable in design, sand controlling result is good, effectively solves grit and gets in the pump with output liquid; Prevent holddown; Device can freely remove with sucker rod, neither influences other operation, also can not bring other any additional work amount to operation.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention;
Among the last figure: cone 1, awl seat 2, valve body 3, fixed base 4, valve ball 5, joint 6.
Embodiment:
In conjunction with accompanying drawing 1, the present invention is done further description:
The present invention mainly is made up of cone 1, awl seat 2, valve body 3, fixed base 4, valve ball 5, joint 6; One end jointing 6 of fixed base 4; The other end of fixed base 4 and awl seat 2 are through being threaded; Awl seat 2 internal fixation valve bodies 3 are provided with valve ball 5 in the described valve body 3, and valve body 3 is equipped with liquid-through hole up and down.
During upstroke, liquid will be taken out under the pressure effect at pump cone will be lifted in oil pumping, liquid through the awl seat liquid chunnel and along the upwards outflow of annular space of cone and oil pipe; In oil pumping during down stroke, cone can get into the awl seat again and seal so can effectively prevent the sand entering pump barrel in the liquid under the double action of gravity and fluid pressure.
When needs are examined pump, on carry sucker rod, this invention will be tripped out ground together with sucker rod, can not have any impact to flow chart.
Reasonable in design, sand controlling result is good, effectively solves grit and gets in the pump with output liquid, prevents holddown, and device can freely remove with sucker rod, neither influences other operation, also can not bring other any additional work amount to operation.
