Abstract

The utility model relates to a coiled tubing, in particular to coiled tubing cable seal head are used in the well logging. Fixed cable awl frame is connected to the device's inside cable awl frame and the cable seal spare of being equipped with of body, body one end connecting cable awl frame fastening screw, cable awl frame fastening screw, and sealing member fastening screw is connected to the body other end, and cable seal spare includes the stripper rubber, and the cable passes cable awl frame fastening screw, cable awl frame, cable seal spare, sealing member fastening screw in order. The utility model discloses a reliable sealed between coiled tubing and the inside cable when preventing that coiled tubing from carrying out the pressure operation, is leaked from terminal emergence of coiled tubing, fixed cable that simultaneously can be reliable, and the inside cable takes place to shift when preventing the coiled tubing operation, and CTU cylinder sliding ring is connected to the cable conductor that can provide random lengths simultaneously on effective sealed basis, makes things convenient for logging operation to use simple structure, low in manufacturing cost.

Description

Coiled tubing cable seal head
Technical field:
This utility model is related to a kind of oil reservoir logging coiled tubing, particularly to a kind of coiled tubing cable seal head.
Background technology:
Coiled tubing transmission well logging timeliness is high, success rate is high, data quality is good it is adaptable to high angle hole and Holes of Complicated Wells are applied Work.But Logging Company's prior art can not meet coiled tubing transmission logging operation needs.By offshore company's technical monopoly, survey Well company does not seal the instrument of coiled tubing end and inside cable, needs to be purchased from offshore company, week needed for buying Phase length, expensive, and spares provisioning difficulty is big, the market competitiveness of restriction company.The coiled tubing cable of offshore company is close End socket internal part replacement cost is high, complex structure, installs and maintaining program complexity, difficulty are big, sealing member reliability is not Height, reserved cable conductor short it is impossible to be used for multiple times it has not been convenient to logging operation use.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of coiled tubing cable seal head, the company of the arrangement achieves Positive sealing between continuous oil pipe and inside cable, when preventing coiled tubing from carrying out pressure operation, occurs from coiled tubing end Leakage, reliably can fix cable simultaneously, prevent inside cable during continuous oil pipe operation to be shifted over, simultaneously can be effective The cable conductor providing random length on the basis of sealing connects CTU cylinder slip ring, facilitates logging operation to use, structure is simple, Low cost of manufacture.Overcome existing coiled tubing cable seal head internal part replacement cost high, complex structure, install and safeguard Maintenance practicess are complicated, difficulty is big, and sealing member reliability is low, reserved cable conductor short it is impossible to be used for multiple times it has not been convenient to logging operation The deficiency using.
Technical solution adopted in the utility model is:A kind of coiled tubing cable seal head, including body;Body interior It is provided with cable cone frame and cable seal, body one end connection cable bores frame fastening screw, cable cone frame fastening screw connects solid Determine cable cone frame, the body other end connects sealing member fastening screw, and cable seal includes stripper rubber, and cable sequentially passes through electricity Cable cone frame fastening screw, cable cone frame, cable seal, sealing member fastening screw, the triumphant skin of cable outer layer fixed by cable cone frame, Space between stripper rubber Expansion sealing cable and inner body wall can be made by screwing hermetic part fastening screw, on this body sidewall It is provided with stop-leak compound hand-hole.
The beneficial effects of the utility model are:The reliability that this utility model achieves between coiled tubing and inside cable is close Envelope, when preventing coiled tubing from carrying out pressure operation, leaks from coiled tubing end, reliably can fix cable simultaneously, Prevent inside cable during continuous oil pipe operation to be shifted over, the electricity of random length can be provided on the basis of effective sealing simultaneously Cable cable core connects CTU cylinder slip ring, facilitates logging operation to use, structure is simple, low cost of manufacture.
Brief description:
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is structural representation of the present utility model.
Specific embodiment:
As shown in figure 1, a kind of coiled tubing cable seal head, including body 1;It is provided with cable cone frame 3 and electricity inside body 1 Cable sealing member 4, body 1 one end connection cable cone frame fastening screw 2, cable cone frame fastening screw 2 is connected cable cone frame 3, Prevent cable cone frame 3 fore-aft travel and rotation.Body 1 other end connects sealing member fastening screw 5, and cable seal 4 includes close Sealing skin, cable sequentially passes through cable cone frame fastening screw 2, cable cone frame 3, cable seal 4, sealing member fastening screw 5, electricity The triumphant skin of cable outer layer fixed by cable cone frame 3, prevents cable displacement during continuous oil pipe operation.By screwing hermetic part fastening screw 5 Space between stripper rubber Expansion sealing cable and body 1 inwall can be made, body 1 side wall is provided with stop-leak compound hand-hole 6, lead to Cross stop-leak compound hand-hole 6 and inject stop-leak compound inside body 1, sealing effectiveness is safe and reliable.Cable core of the present utility model directly from , through whole seal head, length in reserve is unrestricted, facilitates later stage operation for continuous pipe, unlike the seal head of offshore company, needs Carry out cable connection conversion inside seal head, limited by length in reserve, the difficulty that the later stage keeps in repair again is high, and cable connector is located always In highly pressurised liquid (or gas) environment, sealed insulation performance is all unreliable.
It is understood that above with respect to specific descriptions of the present utility model, be merely to illustrate this utility model and not It is limited to the technical scheme described by this utility model embodiment, it will be understood by those within the art that, still permissible This utility model is modified or equivalent, to reach identical technique effect;As long as meeting and using needs, all in this reality Within new protection domain.
