Description
Technical field
The present invention relates to photoelectricity composite sensing optical cable technology field, specifically a kind of photoelectricity suitable in coiled tubing is answered
Close sensing optic cable.
Background technology
With continuing to develop for optical fiber technology, optical fiber sensing technology is increasingly mature, and optical fiber sensing technology is gradually applied to oil
Well test field.In coiled tubing, for some limitations of optical fiber sensing technology, user needs to pass using conditional electronic simultaneously
Sensor coordinates that optical fiber sensing technology is comprehensive that downhole parameters are monitored in real time.Electronic sensor needs to provide electricity from well
Source, if in the case where having laid a sensing optic cable, placing into an oil well cable and being powered for underground electronic sensor, both
Financial cost and the complexity of oil field operation are added, the confined space of coiled tubing has been tied up again.If compound using photoelectricity
Cable, you can solve the above problems.
Optoelectronic composite cable can provide the user the service such as oil well reparation, diagnosis and evaluation of reservoirs.It is based on optics and electrically logical
Letter, optoelectronic composite cable can be connected with surface power source, be downhole production well logging combine instrument, cementing caliper, downhole video into
As the detection instrument such as instrument is powered, and no longer need battery.Optoelectronic composite cable can provide the two-way communication on underground and ground, it is to avoid
Repeatedly lower well operations is cumbersome.
But a series of manufacture difficulty are also brought using optoelectronic composite cable.Because cable outer diameter is fixed, and optical cable it is pressure-resistant,
Pull-off force, optical fiber excess length, outer insulation diameter etc. are required for enough thickness or space, it is therefore necessary to consider all these
Factor can be only achieved the use requirement of user.
The content of the invention
To solve the above problems, the present invention provides a kind of photoelectricity composite sensing optical cable suitable in coiled tubing, have
High temperature resistant, high pressure resistant, highly corrosion resistant, lateral pressure resistant, can Reusability, low cost, small volume the features such as.
The technical solution adopted by the present invention is：A kind of photoelectricity composite sensing optical cable suitable in coiled tubing, including light
