Description
Technical field
The utility model is specifically related to a kind of producing well operation sand-bailing equipment, belongs to oil well operation equipment technical field.
Background technology
Each elephant of China that goes on mutually exploits the middle and later periods, and sand production has become more serious problem, directly has influence on the crude output of oil well, and therefore, each oil field generally adopts the mode of hydraulic sand washing that the long-pending sand in oil well is flushed to ground.But, in traditional hydraulic sand washing work progress, rushed 1 single after, must first termination of pumping then just to connect lower 1 sand washing single, the sand after termination of pumping in sand-carrying production liquid falls after rise, and increase the probability of sand card sand-flushing pipe column, sand washing efficiency is also lower, simultaneously, the sand-laden fluid body returned out from oil well or directly discharge or use through simple precipitation Posterior circle, direct discharge not only contaminated environment, and cause the waste of water resource, use through simple precipitation Posterior circle, fine silt in liquid can be noted in people's well again again, thus reduce the efficiency of sand washing operation, usual hydraulic sand washing will send sand washing pond to well site, remove sand-flushing pipe column, transport sand liquid with tank car and suppress with cementing truck, also to send the additional process such as the oil pipe deepened, usual 2500 meters of sand washings about need with 11000 yuan, needed for often increasing by 500 meters, expense about increases by 1000 yuan, operating cost is high.
China Patent Publication No.: CN201027512Y, patent name is: " a kind of sand sucking device of oil/water well ", by cross over pipe, sand flash valve, sealing drum, plunger, sand device, enters sand valve, draws sand letter and form.Cross over pipe bottom connects with sand flash valve top, and sand flash valve bottom connects with plunger upper part, and plunger is in sealing drum, and sealing drum top diameter of bore is less than the diameter of plunger, sealing drum bottom with enter sand valve top and connect, enter sand valve bottom and draw sand cylinder and connect.Cannot realize continuous wash, cleaning performance is poor, and operation intensity is large, sand removal complex process.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model be to provide a kind of structure simple, practical, can effectively realize right dragging for sand operation, have simultaneously and drag for the producing well operation sand-bailing equipment that sand is effective, drag for the advantages such as sand technique is simple, task difficulty is little.
Producing well operation sand-bailing equipment of the present utility model, comprise sleeve, sand half chamber is dragged on a left side and sand half chamber is dragged on the right side, a described left side is dragged for sand half chamber and the right side and is dragged for sand half chamber and be all articulated and connected by articulated elements and sleeve, a described left side is dragged on sand half chamber and the right inside wall dragging for sand half chamber and is all fixedly connected with hinged seat, in described sleeve, activity runs through pull bar, the activity of described pull bar run through a left side drag for sand half chamber and right drag for sand half chamber top and by being hinged on hinge bar on pull bar and hinged seat is hinged, sand half chamber is dragged on a described left side and right bottom of dragging for sand half chamber all offers some through holes, a described left side is dragged for sand half chamber and the right side and is dragged for sand half chamber inside bottom and be all fixedly installed screen pack.
The utility model beneficial effect: a kind of structure of the present utility model is simple, practical, can effectively realize right dragging for sand operation, has simultaneously and drags for the producing well operation sand-bailing equipment that sand is effective, drag for the advantages such as sand technique is simple, task difficulty is little, when using the utility model, the utility model is allowed to sink to the bottom of producing well, and pushing drawing rod moves down, because pull bar is hinged by hinge bar and hinged seat, when pull bar moves down, a left side drag for sand half chamber and the right side drag for sand half chamber can respectively to the left and right sides, thus the crude oil being mingled with sandstone can enter into a left side drags for sand half chamber and sand half chamber is dragged on the right side, when pulling pull bar to move up, a left side is dragged for sand half chamber and the right side and is dragged for sand half chamber and can draw close to centre and mutually close, by the setting of through hole and screen pack, crude oil drags for sand half chamber and right drags in the process that sand half chamber moves up to be gone out by drop on a left side, and sand half chamber is dragged for and the right side is dragged in sand half chamber in the left side be enclosed in above screen pack by sandstone, and then achieve and get sand operation, the utility model achieves to a great extent gets sand operation to oil well, and have drag for sand effective, drag for the advantage that sand technique is simple, task difficulty is little.
Accompanying drawing explanation
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is sectional structure schematic diagram of the present utility model.
Detailed description of the invention
Producing well operation sand-bailing equipment as depicted in figs. 1 and 2, comprise sleeve 1, sand half chamber 2 is dragged on a left side and sand half chamber 3 is dragged on the right side, a described left side is dragged for sand half chamber 2 and the right side and is dragged for sand half chamber 3 and be all articulated and connected by articulated elements 4 and sleeve 1, a described left side is dragged on sand half chamber 2 and the right inside wall dragging for sand half chamber 3 and is all fixedly connected with hinged seat 5, in described sleeve 1, activity runs through pull bar 6, the activity of described pull bar 6 is run through a left side and drags for sand half chamber 2 and rightly drag for the top in sand half chamber 3 and be hinged with hinged seat 5 by the hinge bar 7 be hinged on pull bar 6, sand half chamber 2 is dragged on a described left side and right bottom of dragging for sand half chamber 3 all offers some through holes 8, a described left side is dragged for sand half chamber 2 and the right side and is dragged for sand half chamber 3 inside bottom and be all fixedly installed screen pack 9.
When using the utility model, the utility model is allowed to sink to the bottom of producing well, and pushing drawing rod moves down, because pull bar is hinged by hinge bar and hinged seat, when pull bar moves down, a left side drag for sand half chamber and the right side drag for sand half chamber can respectively to the left and right sides, thus the crude oil being mingled with sandstone can enter into a left side drags for sand half chamber and sand half chamber is dragged on the right side, when pulling pull bar to move up, a left side is dragged for sand half chamber and the right side and is dragged for sand half chamber and can draw close to centre and mutually close, by the setting of through hole and screen pack, crude oil drags for sand half chamber and right drags in the process that sand half chamber moves up to be gone out by drop on a left side, and sand half chamber is dragged for and the right side is dragged in sand half chamber in the left side be enclosed in above screen pack by sandstone, and then achieve and get sand operation.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
