Abstract
The utility model provides a novel optical cable of an oil and gas well. The novel optical cable comprises an armoured net, wherein a plurality of naked sensing optical fiber are disposed in the armoured net, each naked sensing optical fiber is sleeved with a loosen sleeve pipe and a weaving layer in sequence, and a hollow pipe and a thick steel wire armoured protection layer are disposed outside the armoured net in sequence, and a ring sleeve space formed by an internal wall of the hollow pipe and an external wall of the armoured net is filled with ointment for an optical fiber. The armoured net employs low-carbon thin steel wires, the loosen sleeve pipe employs a modified polypropylene material, the weaving layer employs a high temperature resistant insulation rubber belts, and the hollow pipe employs a stainless steel material. The novel optical cable is light in size, high in wear resistance, high in reliability, stable in transmission signal, good in weight bearing performance, capable of achieving distributed sensor net distribution measurement conveniently, and suitable for hostile environment under the oil and gas well.
Description
Technical field
The utility model relates to Oil/gas Well optical fibre Bragg grating sensing detection system, relates in particular to a kind of new oil gas well optical cable.
Background technology
Due to Oil/gas Well optical fibre Bragg grating sensing detection system can be dynamically, in real time measured oil gas well is monitored, have high temperature resistant, be not subject to the advantages such as electromagnetic interference (EMI), corrosion-resistant, intrinsic sensing, receive gradually oil-gas field development and gerentocratic attention and concern.When building this system, optical cable is the problem that the industrialization of optical fiber sensing monitoring system must be faced and need to solve, and optical cable is the passage of photosynthetic communication, is also bearing the function of carrying the component weight such as downhole sensor simultaneously.But, owing to not adding the common naked Transmission Fibers of protection in prior art, be highly brittle weak, easily brokenly, therefore design that a kind of to be adapted under oil gas field rugged surroundings the long-term Oil/gas Well optical cable using very necessary.
Utility model content
The utility model provides a kind of new oil gas well optical cable, and signal transmission performance is stable, ageing resistance strong, can bear high pressure, the ability of weighing is strong.
The technical solution of the utility model is: a kind of new oil gas well optical cable; it is characterized in that: comprise armouring net; in described armouring net, be provided with some naked sensor fibres; described any naked sensor fibre wraps up loose sleeve pipe and braid outward successively; described armouring net is provided with hollow tube and thicker wire armored protective layer outward successively, fills optical fiber ointment in the ring set space that the outer wall of the inwall of described hollow tube and armouring net forms.
Further, described armouring net adopts low-carbon (LC) finer wire.
Further, described loose sleeve pipe is modified polypropylene material.
Further, described braid is high-temperature insulation adhesive tape.
Further, described hollow tube adopts stainless steel.
The beneficial effects of the utility model are: this new oil gas well optical cable volume is light and handy, wearing quality is high, reliability is high, steady signal transmission, load-bearing property are good, can realize easily the measurement of arranging net of sensor location formula, are applicable in rugged surroundings, using under Oil/gas Well; The utility model armouring net adopts low-carbon (LC) finer wire; play the effect of protection optical fiber; prevent that optical fiber from fractureing under the External Force Actings such as bending; pine sleeve pipe is modified polypropylene material; heat preservation property is good, elastic modulus is high, anti-aging; braid adopts resistant to elevated temperatures insulating tape, can play good buffering shielding action, and the optical fiber between hollow tube and armouring net can effectively prevent that with ointment water logging and hydrogen from soaking.
