Abstract
The utility model provides a kind of downhole instrument string Quick Connect Kit, comprise floating female and public plug, female is provided with righting module with a kind of relative one side of public plug, there is butt-joint clearance and chamfering in righting module, can rapid abutting joint, and female is fixed by first quarter moon ring, first quarter moon ring is fixed by screws on skeleton, there is cost more cheap and eliminate because public plug is bending and cause down-hole fault, connect fewer, the advantage such as more safe and efficient.
Description
Technical field
The utility model belongs to petroleum drilling engineering field, particularly a kind of Quick Connect Kit for device for subsurface measuring string.
Background technology
At present, measurement while drilling (MWD), well logging during (LWD) system have become the indispensable part in petroleum drilling engineering field, the acquisition of downhole data, the most important thing especially, connector is as connection unit important in logger, and the importance of its long-time stable work is self-evident.
As the linkage unit between resistance to compression urceolus in the device for subsurface measuring such as existing MWD/LWD, its structure adopts traditional self-locking connected mode or four or six pin connected modes mostly.Tradition self-locking connected mode is comparatively ancient, is eliminated gradually.Four or six pin connected modes, by the restriction of structure, make Field Force often because of the problem of instrument string connected mode and are difficult to play its operating efficiency.When to direct-connected connect two semiclapboards time, site operation personnel needs good feel just can complete.
This connected mode very easily makes public plug bend; If use brass to be inserted in dividing plate joint, copper scale can be produced and make instrument short circuit.Thus cause the connected system down-hole faults frequent of this four or six pins to occur.
Utility model content
The purpose of this utility model is to provide a kind of downhole instrument string Quick Connect Kit.
The utility model employing technical scheme is: a kind of downhole instrument string Quick Connect Kit, comprise floating female and public plug, female is provided with righting module with a kind of relative one side of public plug, there is butt-joint clearance and chamfering in righting module, can rapid abutting joint, female is fixed by first quarter moon ring, and first quarter moon ring is fixed by screws on skeleton.
Described female is float design.Described public plug has automatic butt jointing device.Described righting block length coordinates with public plug, female, and master-slave socket completed docking before composition threaded collar.
Compared with prior art, the utility model has the advantages that: structure is simple, be easy to processing, and this structure simple and effectively prevents the axial rotation between master-slave socket, moves axially; In such an embodiment, coaxial cooperation between connected system and protection sleeve, even if the axial force that its applied environment is subject to is larger, also there will not be wearing and tearing to produce copper scale phenomenon, improves the reliability of connector to a greater extent.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein 1 is righting module, and 2 is female, and 3 is public plug, and 4 is first quarter moon ring.
Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
A kind of downhole instrument string Quick Connect Kit, comprise floating female 2 and public plug 3, the one side that female 2 is relative with public plug 3 one kinds is provided with righting module 1, there is butt-joint clearance and chamfering in righting module 1, can rapid abutting joint, female 2 is fixed by first quarter moon ring 4, and first quarter moon ring 4 is fixed by screws on skeleton.Therefore master-slave socket 2 and 3 completing docking before composition threaded collar, need require that the length of righting module 1 should be moderate.There is certain interval when docking in righting module 1, to facilitate the docking of master-slave socket 2 and 3.Righting module 1 mainly plays finds docking location and anti-rotation effect fast accurately.
Described female 2 is float design.Described public plug 3 has automatic butt jointing device.Described righting module 1 length coordinates with public plug 3, female 2, and master-slave socket 2 and 3 completed docking before composition threaded collar.
The utility model quick links device, coaxial cooperation after docking completes and between protection sleeve, even if the axial force that its applied environment is subject to is larger, also there will not be wearing and tearing to produce copper scale phenomenon, improves the reliability of connector to a greater extent.
