Abstract
The utility model discloses a connecting-tripping device. The utility model comprises an upper joint (1), a protective covering (3), a male joint (4), a female joint (5) and a fishing joint (6). A suspending short-circuit (2) is connected on the upper joint (1). An external spline is provided on the upper joint (1). An internal spline is provided on the male joint (4). The external spline and the internal spline are meshed mutually and a castellated on-off mechanism is formed. An external spline is provided on the suspending short-circuit (2). An internal spline is provided on the female joint (5). The external spline and the internal spline are meshed mutually and a castellated on-off mechanism is formed. The utility model is widely utilized in the process technology of a plurality of down-hole string which needs releasing and transmitting torques.
Description
The utility model relates to the oil exploitation downhole tool, relates in particular to a kind of on-off connector.
At present, employed on-off connector on the oil exploitation oil-water well, its structure is that male joint is left-hand thread with female joint and links to each other, after instrument was gone into the well and finished predetermined operation, positive tube post made on-off connector throw off in the male and female joint, bottom Liu Jing, top trips out ground, reaches the purpose of uncoupling.But the on-off connector of this structure exists following deficiency and shortcoming:
1, tubing string is gone into the well and is often produced tubing string in the process and just changeing phenomenon, and the instrument that just usually takes place is thrown off phenomenon midway, has to repeat the lower tubular column operation, causes prolong cost up, a series of problems such as operating personnel's labour intensity increase duty cycle.
2, some downhole tool needs positive tube post transfer torque to work, and prior art exactly lacks the function of general positive tube post, does not satisfy the needs of this class instrument well.
For this reason, the utility model provides a kind of on-off connector, and it can solve above-mentioned the deficiencies in the prior art or shortcoming effectively.
The scheme that the utility model solves the problems of the technologies described above is: comprise a kind of on-off connector of top connection, male joint, female joint, sheath and fishing joint, connect in the top connection and hang short circuit, connect sheath outward.On top connection, male joint, female joint and the suspension short circuit spline is arranged all, constitute castellated clutch.External splines is arranged in the top connection, be arranged on its excircle, male joint has internal spline, can be meshed with the external splines of top connection, constitutes castellated clutch.Hanging on the short circuit has external splines, is arranged on the excircle of its underpart; Female joint has internal spline, is meshed with the external splines that hangs short circuit, constitutes castellated clutch.Male joint still is connected for left-hand thread with female joint.When going into the well, the external splines that hangs short circuit cooperates with the female joint internal spline, can transmit the positive torque of tubing string, prevents to give up midway; When the external splines of top connection cooperates with the internal spline of male joint, to hang short circuit and constitute castellated clutch with female joint and throw off, this moment is the tube post just, just can make the disengagement that is threaded of the left-hand thread of male joint and female joint, realizes giving up.
The utility model compared with prior art has following advantage:
1, owing to adopted castellated clutch, when just changeing appearred in down-hole string, on-off connector was not thrown off, and guarantees under the instrument to the precalculated position;
2, can the positive torque of tubing string be passed to the instrument that other links to each other by on-off connector;
3, in the time of need giving up, positive tube post can make on-off connector throw off, and realizes giving up.
Accompanying drawing: be the utility model structural representation
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, hang short circuit 2 one ends and link to each other the other end and female joint 5 spline fitted with top connection 1; Female joint 5 one end left-hand threads connect male joint 4, and the other end links to each other with fishing joint 6, and sheath 3 one ends have internal thread, are connected with top connection 1 external screw thread, and the other end is uncovered shape.The external splines of top connection 1 can be meshed with the internal spline of male joint 4 (being non-engagement state among the figure), when the external splines of top connection 1 is meshed with the internal spline of male joint 4, hangs short circuit 2 and just throws off with the castellated clutch of female joint 5.
Claims (5)
1, a kind of on-off connector, comprise top connection (1), sheath (3), male joint (4), female joint (5) and fishing joint (6), it is characterized in that top connection (1) upward connects suspension short circuit (2), on top connection (1), male joint (4), female joint (5) and the hanging pup joint (2) spline is arranged, constitute castellated clutch.
2, on-off connector according to claim 1 is characterized in that in the top connection (1) external splines being arranged, and is arranged on its excircle.
3, on-off connector according to claim 1 is characterized in that having in the male joint (4) internal spline to be meshed with the external splines of top connection (1), constitutes tooth embedding clutch.
4, on-off connector according to claim 1 is characterized in that hanging on the short circuit (2) external splines is arranged, and is arranged on the excircle of its underpart.
5, on-off connector according to claim 1 is characterized in that in the female joint (5) internal spline being arranged, and is meshed with the external splines of hanging pup joint (2), constitutes castellated clutch.
