Description
Technical field
The present invention relates to oil extraction in oil field field of engineering technology, a kind of release success rate for belonging to horizontal well cable arrangements is high,
The horizontal well cable presetter device that structure is simple, space utilization rate is high.
Background technique
Automating cable used in downhole hardware at this stage is to be arranged horizontally in outside oil pipe to bundle tripping in, under fashionable cable
It is easy that situations such as damaged occurs with tube wall scraping collision；Especially when cable passes through horizontal well inclination section, it is easily rolled fracture, thus
Make cable decentralization failure, prior art can not solve the problems, such as this.
Summary of the invention
It prevents from rolling when horizontal well cable arrangements the purpose of the present invention is designing one kind, wind and crack conditions, mention
High oil pipe space utilization rate, and the horizontal well cable presetter device that cable passes through horizontal well inclination section success rate can be simplified.
The present invention is achieved through the following technical solutions：It by top connection, fishing head, sealing ring, salvage headstock, cut
Disconnected pin, copper ring cut key seat, bearing dead ring, bearing, baffle, central tube, cable ejector, pin for suppressing metal, housing, prevent
Swivel base, stop pin, connector sleeve, sealing ring, fastening nut, lower contact, cable composition；Wherein top connection is sequentially connected from top to bottom
Cut key seat, housing, connector sleeve, lower contact, cable；Cable is fixed on by screw thread and copper ring and is salvaged on headstock by fishing head,
Headstock is salvaged to be fixed on cutting key seat by break pin；Bearing dead ring is sequentially connected bearing, baffle, center from top to bottom
Pipe, cable ejector；Bearing dead ring, baffle mutual cooperation fixing bearing, and the gap of outgoing cable is reserved on baffle,
Cable can be fixed on anti-rotary seat with bearing rotary, pin for suppressing metal by screw thread and copper ring by baffle；Anti-rotary seat, fastening nut with
Central tube is to be threadedly coupled, stop pin and connector sleeve clearance fit；Cable is wrapped on central tube, and is drawn by baffle, cable
Device and housing are fixed out.
There is fishing head center to cross cable passage, and cable directly can cross cable passage from center and pass through.
Baffle, central tube, cable ejector cooperatively form an annular space, and cable is closely arranged in a manner of ring-wound
Cloth is in the space.
Compared with the prior art the present invention has the following advantages that：
The present invention uses preset cable tripping in mode, and cable passes through inside oil pipe and other downhole tools, improves cable
It goes into the well safety；Cable discharges from the inner to the outer, will not block there is a situation where cable is wound during salvaging；Cut pin-shaped
Formula release, fishing success ratio are high.
Detailed description of the invention：Fig. 1 is schematic structural view of the invention.
In figure：1- top connection, 2- fishing head, 3- sealing ring, 4- salvage headstock, 5- break pin, 6- copper ring, 7- break pin
Seat, 8- bearing dead ring, 9- bearing, 10- baffle, 11- central tube, 12- cable ejector, 13- pin for suppressing metal, 14- housing,
15- anti-rotary seat, 16- stop pin, 17- connector sleeve, 18- sealing ring, 19- fastening nut, 20- lower contact, 21- cable.
Specific embodiment：Referring to Fig. 1：The present invention is by top connection 1, fishing head 2, sealing ring 3, salvaging headstock 4, break pin
5, copper ring 6, cutting key seat 7, bearing dead ring 8, bearing 9, baffle 10, central tube 11, cable ejector 12, pin for suppressing metal
13, housing 14, anti-rotary seat 15, stop pin 16, connector sleeve 17, sealing ring 18, fastening nut 19, lower contact 20, cable 21 form；
Wherein top connection 1 is sequentially connected from top to bottom cuts key seat 7, housing 14, connector sleeve 17, lower contact 20, cable 21；Fishing head 2
Cable 21 is fixed on by screw thread and copper ring 6 and is salvaged on headstock 4, headstock 4 is salvaged by break pin 5 and is fixed on cutting key seat 7
On；Bearing dead ring 8 is sequentially connected bearing 9, baffle 10, central tube 11, cable ejector 12 from top to bottom；Bearing dead ring
8,10 mutual cooperation fixing bearing 9 of baffle, and the gap of outgoing cable is reserved on baffle 10, baffle 10 can be rotated with bearing 9,
Cable 21 is fixed on anti-rotary seat 15 by pin for suppressing metal 13 by screw thread and copper ring 6；Anti-rotary seat 15, fastening nut 19 and central tube
11 be to be threadedly coupled, stop pin 16 and 17 clearance fit of connector sleeve；Cable 21 is wrapped on central tube 11, and by baffle 10,
Cable ejector 12 and housing 14 are fixed.
There is fishing head 2 center to cross cable passage, and cable 21 directly can cross cable passage from center and pass through.
Baffle 10, central tube 11, cable ejector 12 cooperatively form an annular space, and cable 21 is with ring-wound side
Formula is closely arranged in the space.
Required length cables 21 in use, be wrapped on central tube 11, fishing head by scene on ground by " zigzag " first
2 lead to the most inner side cable 21 close to center pipe outer wall, and what cable ejector 12 was drawn is then the outermost of close housing 14
Side cable 21 avoids extending out hair inner and outer cable extrusion there is a situation where cable 21 when drawing in this way；The present apparatus is assembled,
Cable 21 is drawn by fishing head 2 from underground after tubing string tripping in, realizes that the oil pipe of cable 21 discharges process.Cable 21 is released
During putting, due to there is the presence of bearing 9, cable 21 can go into the well with winding direction rotation release, avoid and cable friendship occur
The case where fork is lived.
