Fig. 1 is a kind of structure diagram of extension type three-level sealing blowout hookup of the utility model embodiment.Such as Fig. 1
Shown, a kind of extension type three-level seals blowout hookup, including：
First packoff nipple 1, the second packoff nipple 3, third packoff nipple 6, pressure release pipe nipple 4 and choke tube；
High-pressure pipe connector 10 on pressure release pipe nipple 4 is set, overflow pipe fitting 7 is set on the first packoff nipple 1；
Test cable be sealed in by the first packoff nipple 1, the second packoff nipple 3, third packoff nipple 6, pressure release pipe nipple 4 and
The pipe string center of choke tube connection composition；
Choke tube including fixed choke tube 2 and replaces choke tube 5；
Replacing choke tube 5 can disassemble from pipe string and test cable；
It replaces choke tube 5 to be placed in pressure release pipe nipple 4, the position of replacement choke tube 5 disassembled is by the second packoff nipple 3
And be filled in the fixation entrance pressure release of choke tube 2 pipe nipple 4, pipe string entire length shortens.
Further, as shown in Fig. 2 and Fig. 3：Choke tube 5 is replaced, wall is equipped with the cable outlet through its length.
Further, as shown in Figure 1：Component after 2 and second packoff nipple 3 sealed connection of fixed choke tube, with pressure release
After 4 grafting of pipe nipple, then it is fixedly connected with pressure release pipe nipple 4 by adapter coupling 8 and fixing bolt.
Further, as shown in Figure 1：First packoff nipple 1, the second packoff nipple 3 are respectively provided in third packoff nipple 6
Seal gasket and iron pad 9.
Further, the length for replacing choke tube 5 is 0.3-0.4 meters.
Specifically, with reference to Fig. 1, Fig. 4 and Fig. 5, the installation and use of the utility model are described in detail：
During well logging：
1st, logging cable is sequentially passed through into the first packoff nipple 1, fixed choke tube 2, adapter coupling 8, the second packoff nipple
3rd, third packoff nipple 6, pressure release pipe nipple 4；
2 and then stripper rubber is added in the first packoff nipple 1, the second packoff nipple 3 and third packoff nipple 6 respectively
Pad and iron pad 9；
3rd, it is loaded onto among pressure release pipe nipple 4 and third packoff nipple 6 and replaces choke tube 5, then will replace 5 both ends of choke tube
It is inserted into the second packoff nipple 3 and third packoff nipple 6 and is connected as a single entity respectively；
4th, by the second packoff nipple 3, replace choke tube 5 and third packoff nipple 6 using adapter coupling 8, fixing bolt and
Adapter 11 is fixed on pressure release pipe nipple 4；
5th, fixed choke tube 2 is threadedly coupled respectively with first packoff nipple 1 at both ends and the second packoff nipple 3, device
All assembling finishes；
6th, it after device connection, does end and is connect with instrument, instrument, blowout hookup are inserted into lubricator successively
In, screw thread is connect with blowout prevention pipe fitting outside pressure release pipe nipple；
7th, overflow pipe is connect with the overflow pipe fitting 7 of the first packoff nipple 1, it will be on high-voltage tube and pressure release pipe nipple 4
In the connection of high-pressure pipe connector 10, it is possible to carry out test jobs.
When fixed：
1st, when not in use, by packoff nipple 4 with being disassembled on lubricator, adapter 11 is then dismantled, third is sealed
Pipe nipple 6 and replacement choke tube 5 take out, and remove and replace choke tube 5；
2nd, the fixing bolt of adapter coupling 8 is opened, fixed 2 and second packoff nipple 3 of choke tube is pushed into pressure release pipe nipple 4
It is interior, fill the position under detachable 5 sky of choke tube；
3rd, third packoff nipple 6 with the second packoff nipple 3 is docked, and passes through adapter 11 and fix company with pressure release pipe nipple 4
It connects；
4th, it dismantles after replacing choke tube 5, because the length for replacing choke tube 5 is 0.3-0.4 meters, so device overall length
Shorten 0.3-0.4 meters simultaneously, device shorten to 0.9-0.8 meters by original 1.2 meters, meets and blowout hookup is fixed in logging
The requirement that space maximum length with end is 0.9 meter, therefore device can be quickly fixed on together with end on roller.
It can be seen from the above that it when not in use, does not need to destroy cable, it is possible to shorten blowout hookup
Length, eliminate needs to do a series of operation bidirectionals such as end, school cable after chopping cable in the past.Also it is additional that these are just eliminated
Operate the consumption on time and materials.
The blowout hookup connects high-voltage tube, and when high pressure valve is opened, fluid pressure is attenuated in lubricator, pressure release pipe nipple
Interior residual compression is smaller, and residual compression is also smaller to seal gasket active force, so cable will not be because of seal gasket by height
Pressure effect deforms and embraces cable, ensures that instrument can smoothly go into the well.
Embodiment described above only expresses the embodiment of the utility model, and description is more specific and detailed, but simultaneously
Cannot the limitation to the utility model patent range therefore be interpreted as.It should be pointed out that the ordinary skill people to this field
For member, without departing from the concept of the premise utility, several deformations, equal replacement can also be made, improved etc., these
Belong to the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
