Abstract
The utility model relates to a tubing plugging tool in an oil or water well, in particular to an under-pressure operation on-off connector of a high-pressure oil, gas or water well, which comprises a wire rope, a claw, a mandrel, a locking sleeve and a lower joint, wherein the wire rope penetrates through a freeing sleeve to be connected with the claw which locks the locking sleeve in an inner cavity after clamping the mandrel; a spring is sleeved on the mandrel, a locknut is arranged below the spring, and the lower joint and a tubing plug are connected below the mandrel. In construction, a heavy hammer on a steel wire falls on the freeing sleeve and enables the claw to be exposed through the locking sleeve and the compression of the spring to realize the vertical separation of a plug releaser. The tubing plug is extremely convenient to convey and cast a plug, enable the plug to be accurately cast, has simple construction and short time limit, not only improves the work efficiency, but also can lighten the labor intensity.
Description
Technical field:
The utility model relates to oil-water well oil pipe calker; Especially high-pressure oil gas well Operating Pressure on-off connector.
Background technology:
Oil well needs the constant maintenance activity that carries out at work, in order to improve the loss of maintenance speed minimizing output, therefore, carry out Operating Pressure to oil-water well, and stopping up oil pipe in the operation is again process technology key; The oil pipe calker has two kinds of approach in the prior art toward delivered downhole the time, the one, utilize tool pipe to carry, this method transfer position is accurate, and shortcoming is that the construction period is long, the relevant equipment complexity, the 2nd, adopt and freely throw stifled mode, its advantage is to carry the duration short, equipment is simple, and shortcoming is that the blanking plug transfer position is uncertain.
The utility model content:
The purpose of this utility model is in order to overcome above-mentioned shortcoming, and the oil gas water well Operating Pressure on-off connector that provides, it can be by utilizing testing equipment, cooperate and throw in,, realize the input of any well depth position by on-off connector, tubing plug, the position is accurate, and it is simple to throw in equipment, and the construction period is short.
Technical scheme: the task of Ti Chuing for achieving the above object, the utility model is finished by following scheme for this reason: it is made up of wire rope, claw, lock sleeve, mandrel, lower contact; The eyelet that one of described steel wire penetrating is separated the inner chamber upper surface of press-offing is connected with claw; Claw blocks mandrel and is locked lock set within it in the chamber, press-offs and lock sleeve is close to and separate, and is with spring on mandrel, a locking nut is arranged below the spring.Described mandrel lower end links together by screw thread and lower contact, and blanking plug in the lower end screwed connection of lower contact.
Described mandrel is the metal cylinder of a various outer diameter, and left end is cone shape, and a step is arranged more than the conical surface, is positioned at the spring and the locking nut that are with outside the step right part circle of position cylinder and is close to.
The utility model is finished by following working method:
On-off connector is in locking state when the enforcement throwing is stifled, and claw blocks mandrel, and claw is locked to overlap and is locked in the inner chamber, and is in locking state.Earlier testing equipment is installed on the gate of well head production tree during construction, to test above the claw that steel wire is connected to on-off connector, the on-off connector lower contact connects blanking plug again, transfers blanking plug by the test wire rope then, after transferring to assigned address, on put forward wire rope blanking plug seat envelope.Then weight is enclosed within on the wire rope, the well head weight freely fell to free by wire rope and put this moment, compressed spring by lock sleeve under the weight own wt, claw spills, and this moment, claw was thrown off mandrel, and on-off connector is thrown off, release separates up and down, thereby realizes that blanking plug transmits throwing and blocks up.
Because the utility model is provided with one and separates and press-off on lock sleeve, and claw is housed in press-offing separating, this claw blocks the mandrel in it again, and the lock set that is locked then is within it in the chamber, during use, because claw blocks mandrel and is in locking state, when needs are thrown off, only need the input weight to make it to be pressed in to free and put, lock sleeve is compressible spring just, when on when carrying wire rope, claw can be thrown off mandrel again throws off on-off connector voluntarily.The more similar blanking plug of this method compares that to have technology simple, and it is accurate to throw stifled position, and it is short to throw the stifled construction period, increases work efficiency, and can reduce labour intensity again.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Among the figure by 1, separate and press-off, 2, claw, 3, lock sleeve, 4, spring, 5, mandrel, 6, locking nut, 7, lower contact, 8, wire rope forms.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing:
Wire rope 8 is connected above the well head testing equipment among the figure, the other end is connected above the claw 2 of on-off connector, claw 2 be a major part be claw-like have the diameter circle of a varying in size cylinder, pawl on the claw tightly is stuck on the raised step of mandrel 5, mandrel 5 is the real core metal cylinder of a various outer diameter, the tapered shape of left end, one step is arranged more than the conical surface, be close to locking nut 6 at the spring 4 that the cylinder outside that is positioned at step right part position is with, the effect of locking nut is to be used for fixing spring and lower contact 7 positions, separate 1 profile of press-offing and be cylinder, in chamber and the through hole that communicates with each other arranged, wherein wire rope 8 just interts from the through hole of separating the 1 inner chamber upper surface of press-offing and is connected with claw 2 later; Claw 2 is stuck on the raised step of mandrel 5, the cover 3 that is locked is locked in its inner chamber, separating press-offs 1 is close to lock sleeve 3, be in locking state, spring 4 plays a part to support lock sleeve 3, locking nut 6 can be regulated the size of coupling mechanism force, and lower contact 7 in the screwed connection that is positioned at the mandrel lower end, and lower contact a blanking plug (figure is mark not) by screwed connection.
