Abstract
The invention relates to equipment for an oilfield well, and particularly relates to a rapid connection device for a blowout prevention box. The technical scheme is as follows: the rapid connection device is mainly composed of a blowout prevention box joint, a locking barrel, a return spring, a blowout prevention tube joint, a limit steel ball, a blowout prevention tube and a sealing ring, wherein the locking barrel is sleeved outside the blowout prevention tube joint, the return spring is arranged at the junction of the locking barrel and the blowout prevention tube joint, and used for realizing the relative slide of the locking barrel and the blowout prevention tube joint, the locking barrel and the blowout prevention tube joint are sealed via the sealing ring, the blowout prevention box joint is connected to one end of the blowout prevention tube joint, the blowout prevention tube is connected to the other end of the blowout prevention tube joint, and the limit steel ball is arranged at the junction of the blowout prevention tube joint and the blowout prevention box joint. The device disclosed by the invention has the advantages of being convenient in operation, and being safe, labour-saving, simple and convenient, and efficient; and operation personnel can finish connection and separation for the blowout prevention box by controlling a hydraulic mechanism, and can finish inspection for a swabbing tool above the ground, thus preventing the operation personnel from frequently dismounting the blowout prevention tube to inspect the swabbing tool, and reducing risks during operation.
Description
Technical field
The present invention relates to a kind of oil field well and use equipment, particularly a kind of blowout prevention box Quick Connect Kit.
Background technology
In the oil exploitation,, possibly bring out blowout during swabbing operation, so swabbing operation has the well control requirement equally owing to there is the uncertainty of strata pressure.Promptly after pumping blowout or well kick generation, can be effectively controlled.Therefore, in swabbing operation, generally all will install lubricator additional, the blowout prevention box is installed on lubricator top, the bottom of lubricator is connected on the production tree.When blowout, well kick taking place or have other to need, swab and weighted lever are mentioned in the lubricator, then closing well.In use can there be certain wearing and tearing in the seal of pumping instrument, in order not influence the pumping quality, must in time check the pumping instrument on request.When inspection, operating personnel need frequently climb to and connect on the production tree and the dismounting lubricator, inspection pumping instrument.These actions all are that operating personnel stand on the production tree and accomplish, and the production tree top is overhead higher, and smooth surface, and the tumble injury of slipping easily above operating personnel step down in has increased the risk of swabbing operation.
Summary of the invention
The object of the invention is exactly the above-mentioned defective that exists to prior art, and a kind of blowout prevention box Quick Connect Kit is provided, and simple operation has characteristics such as safe, laborsaving, easy, efficient.
Its technical scheme is: mainly be made up of blowout prevention box joint, locking tube, return spring, lubricator joint, spacing steel ball, lubricator, sealing ring; The locking jacket casing is connected on the outside of lubricator joint; The locking tube is provided with back-moving spring with the junction of lubricator joint; Realize both relative slips, through sealing ring sealing locking tube and lubricator joint, lubricator joint one end connects blowout prevention box joint; The other end connects lubricator, and the junction of lubricator joint and blowout prevention box joint is provided with spacing steel ball.
The invention has the beneficial effects as follows: this device simple operation; Have safe, laborsaving, easy, efficient; The connection that operating personnel just can accomplish the blowout prevention box through the control hydraulic mechanism with separate; Just can accomplish the inspection of pumping instrument on the ground, thereby avoid operating personnel, reduce the risk in the operation because of frequent dismounting lubricator inspection pumping instrument.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention;
Among the last figure: blowout prevention box joint 1, locking tube 2, return spring 3, lubricator joint 4, spacing steel ball 5, hydraulic cavities 6, lubricator 7, sealing ring 8.
The specific embodiment:
In conjunction with accompanying drawing 1, the present invention is done further description:
The present invention mainly is made up of blowout prevention box joint 1, locking tube 2, return spring 3, lubricator joint 4, spacing steel ball 5, hydraulic cavities 6, lubricator 7, sealing ring 8; Locking tube 2 is socketed in the outside of lubricator joint 4; Locking tube 2 is provided with back-moving spring 3 with the junction of lubricator joint 4, realizes both relative slips, and both spaces form hydraulic cavities 6; Through sealing ring 8 sealing locking tubes 2 and lubricator joint 4; Lubricator joint 4 one ends connect blowout prevention box joint 1, and the other end connects lubricator 7, and lubricator joint 4 is provided with spacing steel ball 5 with the junction of blowout prevention box joint 1.
During use, blowout prevention box joint is installed on the blowout prevention box, and the lubricator joint is connected with lubricator, realizes being connected and separating of blowout prevention box joint and lubricator joint through moving of locking tube.When inspection pumping instrument, operating personnel need not frequently to climb to and connect on the production tree and the dismounting lubricator.Only need to rely on the gravity of blowout prevention box just can realize connecting, and when swabbing operation, can not extract.When needs are dismantled, open locking device through hydraulic control, watch out for the spray box on only needing gently just can realize dismantling.Can effectively avoid operating personnel to cause the risk of tumble injury because of frequent dismounting blowout prevention box.After the controlling organization action, the locking tube slides smooth and easy, does not have catching phenomenon, can lock smoothly and release.The seal of blowout prevention box Quick Connect Kit, under the situation of bearing the pumping fluid pressure, sealing is reliable, does not come off and the seepage phenomenon.Good seal between blowout prevention box jointing and the lubricator jointing, the leakproof phenomenon, connect move when separating smooth and easy, no catching phenomenon.
