Below with reference to accompanying drawing and describe the present invention in detail in conjunction with the embodiments.It should be noted that when not conflicting, the embodiment in the application and the feature in embodiment can be mutually combined.
If Fig. 5 is to shown in 10, according to embodiments of the invention, test cable wrap draws together test cable capillary tube 11, test cable core 12 and connecting line 13.
Wherein, test cable capillary tube 11 has the receiving opening 111 axially through test cable capillary tube 11.Test cable capillary tube 11 is used for holding test cable core 12.Test cable core 12 is arranged in the receiving opening 111 of test cable capillary tube 11, and the first end of test cable core 12 is between first end and the second end of test cable capillary tube 11 of test cable capillary tube 11, and between the first end of the first end of test cable core 12 and test cable capillary tube 11, there is the first axial distance.The first axial distance between first end and first end of test cable capillary tube 11 of test cable core 12 may be used for holding connecting line 13.Connecting line 13 is stretched in test cable capillary tube 11 by the first end of test cable capillary tube 11, and is connected with test cable capillary tube 11 crimping.Connected by connecting line 13, adopt the mode of crimping to connect, thus improve the ability bearing pulling force of test cable.
In the present embodiment, in order to process the test cable between the first end of test cable core 12 and the first end of test cable capillary tube 11 with the first axial distance easily, the tube wall of test cable capillary tube 11 is provided with cable core handle hole 112, cable core handle hole 112 radially extends along test cable capillary tube 11, and the tube wall running through test cable capillary tube 11 connects with receiving opening 111, the test cable core 12 between the first end of cable core handle hole 112 and test cable capillary tube 11 can pass through cable core handle hole 112 and take out.
Preferably, the diameter of cable core handle hole 112 is 2mm.The diameter of cable core handle hole 112 can take out the diameter of test cable core 12 according to different need and select, it is ensured that can take out test cable core 12 smoothly.
In the present embodiment, the first axial distance tested between the first end of cable core 12 and the first end of test cable capillary tube 11 is 20cm.
According to a further aspect in the invention, test string includes coiled tubing 20 and test cable 10.
Wherein, coiled tubing 20 has the cable installing hole 21 axially through coiled tubing 20.Coiled tubing 20 is used for holding test cable 10.
Test cable 10 is arranged in cable installing hole 21, and test cable 10 is above-mentioned test cable 10.The test cable 10 of this test string have employed above-mentioned test cable, the better effects if of its bearing capacity, and intensity is higher, and ruggedness is better.
Preferably, test string includes many group test cable groups, and each test cable group includes the two test cables 10 be arrangeding in parallel, and the two ends of connecting line 13 are stretched in the test cable capillary tube 11 of test cable 10 correspondingly.The quantity of the test cable 10 in test string can be selected according to actually used demand.
Connecting line 13 is short capillary, and the diameter of short capillary is 3.5mm.
If the quantity of the test cable 10 in test string is even number, then can pass through a connecting line 13 and connect two test cables 10, so easily facilitate processing, and more save material, it is possible to effectively reduce production cost, it is to avoid waste.
Test string includes at least one single test cable group, and single test cable group includes a test cable 10, and the two ends of connecting line 13 are all stretched in test cable capillary tube 11.
The steel wire rope that connecting line 13 is diameter 2mm of the test cable of single test cable group.If being provided with odd number test cable 10 in test string, then the two ends of a connecting line 13 all can be stretched in the test cable capillary tube 11 of test cable 10, be achieved in connecting.In order to guarantee to be stretched into by connecting line 13 easily in test cable capillary tube 11, the diameter of connecting line 13 should be smaller.
According to a further aspect in the invention, it is provided that a kind of test string manufacture method, test string manufacture method is for manufacturing above-mentioned test string, and test string manufacture method includes:
Drill process, bores the hole radially extended along test cable capillary tube 11, to form cable core handle hole 112 on test cable capillary tube 11;
Take cable step, from cable core handle hole 112, the test cable core 12 between first end of cable core handle hole 112 to test cable capillary tube 11 is blocked, and take out cutting the test cable core, to form taking-up part 14;
Connecting line filling step, first end of one end of connecting line 13 test cable capillary tube 11 from which is stretched in the receiving opening 111 of test cable capillary tube 11, and crimp, the first end that the other end of connecting line 13 tests cable capillary tube 11 from another root is stretched in the receiving opening 111 testing cable capillary tube 11, and crimp, or the two ends of connecting line 13 are all stretched into from the first end of test cable capillary tube 11 in the receiving opening 111 of test cable capillary tube 11, and crimp;
Drag dress step, steel loading cord 30 will be dragged to be wound on connecting line 13, and the test cable 10 on connecting line 13 is pulled in the cable installing hole 21 of coiled tubing 20, and form test string.
The ability of the test string bearing capacity manufactured by the method is better, more durable.
In the present embodiment, needing the diameter pulling the test cable capillary tube 11 of test cable 10 is Φ 6.35, the cable core handle hole 112 of drill diameter 2mm on test cable capillary tube 11, to extract close beta cable core 11 out, the part extracted out is formed takes out part 14, makes test cable capillary tube 11 front end leave the blank pipe section of 20cm.
If the test cable 10 of even numbers need to be pulled, then the test cable capillary tube 11 that two of the short capillary of a Φ 3.5mm is inserted Φ 6.35 respectively is internal, and carries out the crimping in more than 4 roads in junction, and crimping is adapted to hydraulic crimping machine.Then enter in coiled tubing 20 with the two test cables 10 that steel loading cord 30 pulls making complete around ring that drag of Φ 2.4mm.
If the test cable 10 of odd number need to be pulled, it is necessary to insert the steel wire rope of a Φ 2mm at test cable capillary tube 11 internal loopback, then carry out the crimping in more than 4 roads in junction, carry out afterwards dragging dress.
In test string manufacture process, two kinds of connecting lines 13 can use (testing cables suitable in 3) with the connected mode testing cable capillary tube 11 simultaneously, also one therein (testing cable suitable in 1-2 root) can only be used, if test cable quantity is more than 4, then can comply with and select to use.
In from the description above, can be seen that, the above embodiments of the present invention achieve following technique effect: by the test string manufacture method of the present invention, by testing cable capillary tube grafting crimping connected mode, the test string after connection enables to junction and bears high strength tension in narrow and small coiled tubing.
In manufacturing process, test cable is removed the cable core of 20cm.Connecting line is inserted respectively 2 test cables (or 1 test cable of two ends insertion), uses hydraulic tongs crimping to produce deformation.Use steel wire to be wound around looper in junction to connect.
High strength tension can be born after adopting the crimping deformation of the structure of this big pipe box tubule, multiple tracks.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
