Specific embodiment
Detailed specific description is done to the present invention with reference to the accompanying drawing.
The structure of measuring system down-hole equipment insulating short section provided by the invention as shown in Figure 1, include top connection 1, under connect
First 6, upper insulation positioning ring 2, lower insulation positioning ring 5, resin adhesive layer 8, key 4 and glass reinforced plastic cloth 3, wherein top connection 1 and lower contact
6 are all made of the production of nonmagnetic steel material as the outer tube of measurement while drilling drilling tool in open circles tubulose, top connection 1 and lower contact 6.On
The lower part of connector 1 and the top of lower contact 6 are respectively overlapping part A and overlapping part B, and wherein overlapping part A, which is set in, takes
On the B of socket part position, glass reinforced plastic cloth 3 is enclosed on overlapping part A.
Upper insulation positioning ring 2, lower insulation positioning ring 5 and resin adhesive layer 8 between top connection 1 and lower contact 6 and make
The two is isolated, wherein upper insulation positioning ring 2 is located at the top of overlapping part B, lower insulation positioning ring 5 is located at overlapping part A's
Bottom, resin adhesive layer 8 are adhesively fixed between overlapping part A and overlapping part B and with the two, and overlapping part A is equipped with note
Glue hole 7, the resin glue is epoxy resin, by being flowed between overlapping part A and overlapping part B in hole for injecting glue 7.
4 keyways are at least evenly distributed on overlapping part A, the keyway penetrates overlapping part A and resin adhesive layer 8,
The bottom of keyway is located in overlapping part B, and key 4 is fixed in keyway, and the key 4 is insulation key.Institute in the present embodiment
The keyway stated is equipped with 6, and 6 keyways are scattered in two layers up and down, and every layer is distributed with 3, and in the keyway of 3 be located on the same floor
It is equidistant between any two.
The material of heretofore described upper insulation positioning ring 2, lower insulation positioning ring 5 and key 4 is high-intensitive engineering plastic
Expect polyether-ether-ketone (PEEK).
Measuring system down-hole equipment insulating short section provided by the invention is processed and is worked in the following manner: firstly, according to setting
The structure of meter using nonmagnetic steel processing top connection and lower contact, using high-strength engineering plastic process insulation positioning ring and it is lower absolutely
Edge positioning ring.Will be fixed after top connection, lower contact, upper insulation positioning ring, the assembling of lower insulation positioning ring, liquid is injected from hole for injecting glue
State epoxide-resin glue mills out 6 keyways in the overlapping part of upper and lower connector after epoxide-resin glue parches, and divides two layers, every layer
3 keyways are evenly arranged, keyway passes through top connection, epoxy glue layer reaches lower contact certain depth (not penetrating), then uses
PEEK material processes 6 keys, and key is installed in keyway.One layer of glass is finally wrapped up outside the overlapping part of upper lower contact
Steel cloth.
From the structure of the insulating short section it is found that by upper insulation positioning ring, lower insulation positioning ring and epoxy between upper lower contact
Resin glue separates to play insulating effect, at the same epoxide-resin glue by upper lower contact secure bond together, can play certain
Transmitting torque and pressure effect, furthermore the key of 6 high intensity PEEK materials processing, which plays, transmits torque and drawing, pressure
It is main with using, since torque and drawing, pressure are undertaken by epoxide-resin glue and 6 high intensity PEEK keys, thus insulating short section is not only
Insulating effect can be played, integral strength is also very high, can sufficiently bear torque, pulling force and pressure in drilling process.
The glass reinforced plastic cloth of outside package plays the role of protecting PEEK key.
