Specific embodiment
The deep-sea test string connector includes upper tubing string 1, lower tubular column 2, sliding sleeve 3 and bindiny mechanism 4.Lower tubular column 2 is change
Footpath body, the thread set of upper tubing string 1 is on lower tubular column 2.Lower tubular column 2 and the provided circumferentially about of upper tubing string 1 have what multiple was interconnected
Slide opening 5, slide opening 5 is connected with the centre bore of lower tubular column 2 and upper tubing string 1.It is provided with the upper tubing string 1 of the top of slide opening 5 of upper tubing string 1
Flange 6, sliding sleeve 3 is movably installed with upper tubing string 1 by flange 6;Sliding sleeve 3 is made up of upper sliding sleeve 8 and low sleeve 9, the He of upper sliding sleeve 8
It is threadedly coupled between low sleeve 9.The sealing slip of the inwall of sliding sleeve 3 and flange 6 is fitted and connected, thus make sliding sleeve 3 and upper tubing string 1 it
Between form the separate upper chamber and lower chambers split by flange 6 and formed, back-moving spring 10 is provided with upper chamber.Upper pipe
Hydraulic pressure oil duct 11 is provided with post 1, one end of hydraulic pressure oil duct 11 connects with lower chambers.
The bottom of slide opening 5 of lower tubular column 2 is provided with engaging lug 7, slide opening 5 and is movably installed with company by engaging lug 7 and bearing pin
Connection mechanism 4.
Bindiny mechanism 4 is made up of sliding block 12, connecting rod 13 and connecting shaft block 14, and sliding block 12 is prismatoid, and the top of sliding block 12 sets
Engaging lug 7 is equipped with, sliding handle 15 is symmetrically arranged with the sliding block 12 of the both sides of engaging lug 7.
Connecting shaft block 14 is the tapered cuboid in one end, and the top and bottom of connecting shaft block 14 are respectively arranged with engaging lug 4.Even
The upper end of bar 13 is flexibly connected by engaging lug 7 and bearing pin with sliding block 12, and the lower end of connecting rod 13 is by engaging lug 7 and bearing pin and connecting shaft block
14 are flexibly connected.
The outer surface of connecting rod 13 of bindiny mechanism 4 is provided with locking projection 16, and locking projection 16 is connected with sliding sleeve contact.
Chute 17 is provided with the deep-sea test string connector on the slide opening wall of the both sides of slide opening 5 of tubing string 1, sliding block 12 leads to
Cross sliding handle 15 to be slidably connected with upper tubing string 1 with the cooperation of chute 17, the purpose of chute 17 is to be operated limit to bindiny mechanism 4
Position, one end of sliding block 12 is extended in the centre bore of tubing string 1 by slide opening 5(Referring to accompanying drawing 1-7).
The deep-sea test string connector is connected by the centre bore internal thread of upper tubing string 1 with drilling rod, during work, bindiny mechanism
It is in contraction state under 4 normal conditions, in the course of work, the deep-sea test string connector is descending by drilling rod, so that well head
Test string 19 progressively inserted by the centre bore of lower tubular column 1(Referring to accompanying drawing 8).
With the insertion of test string 19, the top of test string 19 and the centre bore inner slide 12 for extending to upper tubing string 1
Contact, and as the progressively insertion of test string 19 promotes sliding block 12 up along chute 17, during this, sliding block 12 drives and connects
Bar 13 and connecting shaft block 14 are progressively stretched(Radial contraction), connecting shaft block 14 is embedded on test string 19 and connecting shaft block 14 pairs
In the bayonet socket 20 answered, now, the alignment pin 21 on test string 19 is placed exactly in locating slot uniform on the bottom end face of lower tubular column 2
In 18, the connection of test string 19 and the connector is thus completed.The effect of alignment pin 21 and locating slot 18 is to strengthen connecting shaft block
14 with the buckle intensity of bayonet socket 20, prevent test string 19 to be subjected to displacement with the connector.
1. after the completion of above-mentioned action, suppressed by hydraulic pressure oil duct 11, force sliding sleeve descending, and with the lock of the outer surface of connecting rod 13
Tight projection 16 is contacted, so that limiting sliding block 12 is unable to radial expansion, is thus completed test string 19 and is locked with the connection of the connector
Tightly(Referring to accompanying drawing 9).After sliding sleeve is contacted with locking projection 16, sliding sleeve can not continue to move down, and hydraulic pressure reaches capacity, you can
Judge that test string 19 has been connected to finish.
2. development length of the sliding block 12 of the deep-sea test string connector in the centre bore of upper tubing string 1 be not blocking center
Hole runner is advisable, when test string 19 is separated with the connector, only need to be by the pressure release of hydraulic pressure oil duct 11, in the work of back-moving spring 10
It is up with low sleeve, and completely with completely disengaged from connecting rod 13 and contact after, connecting shaft block 14 from bayonet socket 20 is forced by above carrying drilling rod
Inside exit, realize that the connector is separated with test string 19.
The deep-sea test string connector construction is simple, practicality is good, improves convention connectors
Cannot the defect that whether is fully connected of discriminating test tubing string;With simple to operate, reliability is high;Take small volume
Feature, improves the reliability of the connection of deep water test string 19;Meet the requirement of deep-sea test jobs.
