Abstract
The present invention relates to a kind of brake pipe nipples for horizontal well conveying tractor perforation tool, and brake the brake control mechanism that is spirally connected between top connection and brake lower contact；The brake pad of the brake control mechanism is located among two support arm one end, and is connected and fixed with steel pin, and the two support arm other ends are fixed on backup block by steel pin, and spring is equipped between backup block and catch bar, and catch bar is connect with electric machine assembly.In horizontal well perforation construction, the present invention and releasing pup joint, rotating short-knot, upper centralizer, magnetic orientation pipe nipple, tractor, lower centralizer, flexible nipple, safe power supply pipe nipple, damper, perforator and ball gun breech are combined into horizontal well conveying tractor perforation tool, are adaptable to upwarp operation under horizontal well perforation operating condition；Reasonable frictional resistance can be provided, realize that well tool is remain stationary in upwarping horizontal well or uniform speed motion state, effective control tractor perforation tool motion state greatly improve the security reliability of construction.
Description
Technical field
The invention belongs to petroleum works perforating technology fields, and be especially adapted for use in horizontal well perforation operation is used for horizontal well
Convey the brake pipe nipple of tractor perforation tool.
Background technique
When upwarping Horizontal Well rake angle greater than 98 ° of tractor perforating jobs, tractor perforation tool is in own wt
Or perforation acts under generated impact force action, it may appear that the speed of service is difficult to control, it can not be made to be able to maintain in specific position
Static or uniform speed motion state, such case be easy to cause the Compression and Expansion of perforating depth, are unable to accurately control perforating depth, shadow
Ring construction quality；It will lead to tool when serious and cross cable, cable wringing damage or cable fracture, generating tool string is caused to fall well
Etc. engineering accidents.To guarantee to upwarp the quality and safety of horizontal well perforation operation, need a kind of to penetrate upwarping horizontal well tractor
Hole operation can be effectively controlled the measure of tractor perforation tool motion state.
Generally use increasing resistance centralizer at present to alleviate equipment slide downward, but the resistance that generates of this method is smaller and not
It can change, drag size cannot be changed according to horizontal well difference gradient is upwarped, when encountering hole deviation angle greater than 98 degree, tractor is penetrated
Hole tool still can move downward state in acceleration, can not prevent the generation of accident.
Summary of the invention
The purpose of the present invention is statuses in view of the above technology, it is desirable to provide one kind is adaptable to upwarp to be made under horizontal well operating condition
Industry；Tractor perforation tool can be effectively controlled in the motion state for upwarping horizontal well, hence it is evident that well perforating job safety of improving the standard
For horizontal well conveying tractor perforation tool brake pipe nipple.
The implementation of the object of the invention is that the brake pipe nipple of tractor perforation tool is conveyed for horizontal well, in brake
Be spirally connected brake control mechanism between connector and brake lower contact；The brake pad of the brake control mechanism is located at two support arm one end
Centre, and be connected and fixed with steel pin, the two support arm other ends are fixed on backup block by steel pin, between backup block and catch bar
Equipped with spring, catch bar is connect with electric machine assembly.
In horizontal well perforation construction, the present invention and releasing pup joint, rotating short-knot, upper centralizer, magnetic orientation pipe nipple, traction
Device, lower centralizer, flexible nipple, safe power supply pipe nipple, damper, perforator and ball gun breech are combined into horizontal well conveying traction
Device perforation tool is adaptable to upwarp operation under horizontal well perforation operating condition；Reasonable frictional resistance can be provided, upwarped to overcome
The technical deficiency occurred in horizontal well construction realizes that well tool is remain stationary or uniform speed motion state in upwarping horizontal well,
Effectively control tractor perforation tool motion state, greatly improves the security reliability of construction.
The present invention controls the frictional resistance size between brake pad and the borehole wall by motor control telescopic spring degree, real
Existing tractor perforation tool combination upwarps motion state required for horizontal well operations in different gradients.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawings.
Referring to Fig.1, brake top connection of the invention is connect by screw thread with upper centralizer.It brakes under top connection 1 and brake
Be spirally connected brake control mechanism 2 between connector 8.The brake pad 9 of the brake control mechanism is located among two support arms, 6 one end, and
It is connected and fixed with steel pin 7, the two support arm other ends are fixed on backup block 10 by steel pin, are pacified between backup block and catch bar 4
There is spring 5, catch bar is connect with electric machine assembly 3.Electric machine assembly uses common electric machine assembly.
When brake pad 9 struts, electric machine assembly 3 drives 4 transverse movement of catch bar, and compressed spring 5 pushes backup block 10 mobile,
To drive brake pad to strut upwards, struts and determine that brake pad generates the size of frictional force on the borehole wall apart from size, maximum is rubbed
It wipes power and is not less than 400kg, realize that control tractor perforation tool is upwarping horizontal well motion state, can guarantee tractor perforation work
Stationary state needed for having operation or uniform motion requirement.
When brake pad collapses, electric machine assembly drives the transverse movement of catch bar opposite direction, spring reset, and support arm drives brake
Pawl moves down, and final brake pad collapses in brake pipe nipple,
When upwarping horizontal well tractor perforating job, tractor perforation tool is generated in own wt or perforation effect
Under impact force action, tractor perforation tool can generate downward accelerated motion, be unable to control tractor perforation tool specific
Position is remain stationary or uniform speed motion state, can not high fighting capacity fulfil assignment safely.The present invention passes through motor control telescopic spring
Degree keeps the frictional resistance size between brake pad and the horizontal borehole wall adjustable, realizes that upwarping horizontal well in different gradients makees
Motion state required for industry effectively controls tractor perforation tool motion state, greatly improves the security reliability of construction.
