Abstract
The utility model relates to an oil dredge tool of an oil well, which particularly relates to an oil dredge swab which is used to prevent sand blocking, prevent overloading, prevent a glue flap from tripping and scrap residual oil of a cannula. The oil dredge swab comprises a sliding bar, a sliding block, a safe pin and a sliding flap, wherein the sliding flap is equipped with an upper flip and a lower flip, wherein the upper flip and the lower flip are connected together through a screw, and the sliding flip and the sliding block can slide on the sliding bar. Oil can be dredged when the oil dredge swab is upwards lifted, residual oil on cannula walls can be cleaned in the process of downwards landing, and the phenomenon of oil damping and glue flip dropping can be avoided, flow resistance is small when oil is dredged, fluid is easy to get into the upper portion of the oil dredge swab, and the purpose of improving production ageing effect is achieved. The oil dredge swab can be widely used in oil wells with low production in oil fields.
Description
Technical field:
The utility model relates to oil well and drags for oily instrument, and the anti-glue lobe of especially a kind of sand control card overload prevention comes off and scrapes sleeve pipe Residual oil swab.
Background technology:
Dragging for oil for oilfield exploitation later stage or hyposmosis, low production capacity oil well with swab, is the effective mining type that reduces cost, and the performance of swab directly has influence on the output of dragging for oil and drag for the cost of oil.Phenomenons such as sand and foreign material card, glue lobe come off because the cause specific of oil well, swab originally in use often occur, the resistance of casing wall Residual oil, overburden safeguard protection are malfunctioning cause invalid construction, sometimes even production accident takes place.
The utility model content:
The utility model purpose is in order to overcome above-mentioned shortcoming, and the anti-glue lobe of a kind of sand control card overload prevention that provides comes off and scrape the sleeve pipe Residual oil and drag for oil and promptly three anti-one scrape the swab of function.
This swab has the fluid resistance of reducing function, makes fluid flow into swab top easily, thereby reduces production accident, improves crude output.
The technical scheme that its technical problem that solves the utility model adopts is:
For realizing above-mentioned task, the utility model is made up of slide bar, slide block, safety pin, sliding lobe for this reason, and described sliding lobe is equipped with epivalve, hypovalve, connects together by screw, and sliding lobe and slide block can slide on slide bar.
Described hypovalve lower limb shape is the monodentate shape, in the both sides of tooth eddy channel is arranged, and has anti-sand launder in the epivalve.
By the screw thread at slide bar two ends, be connected with the wire rope that is used for the well head lifting and the weight linear meter of lower end respectively during use.
When swab was descending, the sliding lobe that is located at slide bar one side upwards slided under friction and pressure effect, and two sliding lobes that are installed on the slide bar stagger relatively, made the interior liquid of well flow into top by runner;
When swab was up, another sliding lobe was in friction, under the effect of fluid column and self gravitation, integral body is displaced downwardly on the sliding lobe synchronously, two sliding lobes constitute a closure mechanism thus, make the effect of sliding lobe by upper and lower glue lobe with the upper and lower partition of sleeve pipe, thereby reach sealing purpose.The equipment of well head is by the castering action of steel wire afterwards, and it is up that swab is continued, until liquid is sent in the Oil container of ground.
As oily overload situations occurring dragging for, the safety pin above the swab is cut off during the utility model uses, epivalve and hypovalve stagger like this, and liquid is unloading automatically under action of gravity.
Because the sliding lobe of installing in the device, upper and lower lobe forms an integral body on slide bar, and is convenient especially when therefore dragging for oil, not only can the sand control card, anti-junk, can stop sliding lobe again and go up hypovalve to come off and the well accident occurs falling, can scrape the decannulation Residual oil again, flow resistance is reduced, improve oil well output.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Among the figure: by 1, slide bar, 2, slide block, 3, safety pin, 4, epivalve, 5, hypovalve, 6, sliding lobe, 7, screw forms.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
Slide bar 1 is that two ends are processed with the Metallic rod that screw thread is used to connect Hoisting System and weighted lever among the figure; chute is arranged on slideway; guarantee that sliding lobe 6 and slide block 2 slide up and down at slide bar; the safety pin 3 of slide block 2 is fixed in the safe pin-and-hole of slide bar 1; be used to determine to be contained in the epivalve on the sliding lobe 6 and the position of hypovalve; and be fixed on one with sliding lobe; epivalve 4; hypovalve 5 is that metal construction is cylindric; wherein there is eddy channel the hypovalve 5 lower limb shapes both sides that are monodentate shape tooth; can strike off the residue on the casing wall; survey the intact degree of sleeve pipe; play the drifting effect; the eddy channel that while is provided with according to the hydraulic principle both sides; can reduce the liquid flow resistance that makes progress; in epivalve 4, be provided with the sand control groove shape as the drift size gauge tool that is inverted; can stop sand and junk during use drops into behind the swab top and sleeve-shaped wedgewise state jam swab; slide block 2 is fixed on slide bar 1 bottom by safety pin 3 during work; sliding lobe 6 is made for the rubber material; be fixed on slide bar 1 middle part with safety pin 3; top connects and wire rope links to each other with universal by screw thread, and the bottom links to each other with weighted lever by screw thread.
