Description
Technical field
The utility model relates to a kind of oil well operation equipment, particularly a kind of oil well operation plug-removing device.
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.The each elephant of current China enters the middle and later periods of exploitation in succession, sand production problem is on the rise, sand buries oil reservoir or pit shaft sand plug causes oil well to stop production, shake out and make that ground and underground equipment are seriously denuded, sand card, maintenance load such as sand washing inspection pump, the clear tank in ground etc. increases severely, and also can cause cave-in and damage sleeve pipe when shaking out serious.The means solving down-hole casing inner product sand mainly utilize sand washing operation sediment outflow.And continuous sand flushing and supporting environmental protection apparatus for work can solve sleeve pipe inner product sand and ground pollution problem effectively.
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
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of oil well operation plug-removing device.
Its technical scheme is: comprise well head, well head self-sealing device, oil pipe, elevator, conversion joint, sand clean out pipe, sand pump, cyclone separator, well head top is bolted well head self-sealing device, the top of described well head self-sealing device connects conversion joint, the outside of conversion joint is provided with elevator, the inside connected pipes of well head self-sealing device, well head self-sealing device saves with conversion the working space coordinating formation one closed, the outside of well head self-sealing device is provided with sand clean out pipe, the outside of well head connects takes out sandpipe, the described outside of taking out sandpipe connects sand pump, described sandpipe of taking out is provided with cyclone separator.
Described cyclone separator comprises rotary fluid, described rotary fluid is pyramidal structure, the inside of rotary fluid is provided with screw rod, rotary fluid is provided with liquid inlet, liquid outlet and spilling port, the liquid inlet of rotary fluid connects takes out sandpipe outlet, the liquid outlet of rotary fluid connects sand clean out pipe by circulation pipe, and the spilling port of rotary fluid connects riffler.
The beneficial effects of the utility model are: well head self-sealing device saves with conversion the working space coordinating formation one closed, prevent sand-laden fluid from overflowing, cyclone separator good separating effect, improve separative efficiency, effectively prevent operation soil-well jam, the screw rod of cyclone separator inside rotates, and parting liquid is moved along the tangential direction of rotary fluid pyramidal structure under the effect of the pressure, liquid produces rotary motion, increases work efficiency.
