Abstract
The utility model discloses a kind of optical fiber logging cable, comprise the optical fiber of outer armour and outer armour inside, described outer armour is stainless steel armor, and described optical fiber is peripheral and stainless steel armor inside is also provided with stainless steel bushing pipe.Polyurethane adhesive is filled with between described stainless steel bushing pipe and stainless steel armor.Greasy for preventing water is filled with between described optical fiber and stainless steel bushing pipe.Polyurethane adhesive padded coaming is filled, and interior pipe can be made to keep placed in the middle, and make two-layer between there is no relative motion.For the infringement of hydrogen is down to minimum, oil well test optical cable inner tube adopts the coating of low hydrogen penetration material, and outside this coating, plate the hard anti-scratch material of one deck, ensures the integrality of coating.Inner tube has squeezed liberation of hydrogen packing material simultaneously, and this material has very strong viscosity, can offset the shearing force of optical cable when winding, expansion, prevent optical fiber to be subject to microbending.
Description
Technical field
The utility model relates to oil field cable, specifically a kind of optical fiber logging cable.
Background technology
The fast development of optical-fibre communications in recent years and measuring techniques for optical fiber, for the leap of down-hole multiparameter follow-on test brings dawn, because in optical fiber testing system, its downhole sensor is not containing electronic component, long-time stability are good, have the multinomial test function such as temperature, pressure, due to the advantage of measuring techniques for optical fiber, the research of oil well measuring techniques for optical fiber has become one of focus of international petroleum Development and Production field tests research at present.
Optical cable transmission has lightweight, the advantage such as volume is little, long transmission distance, capacity are large, signal attenuation is little, electromagnetism interference, is extensively utilized in the communications field.But cable configuration is complicated, description of materials is various, and except technical parameter is had nothing in common with each other, many latencies are as also very large in differences such as materials, production technology, equipment.Therefore, optical cable manufacturing procedure of logging well is a complicated technique.
Mainly " excess length control " and control " hydrogen loss " affect two aspects to the critical process of optical cable.It is crucial that excess length control in fiber secondary coating technique, the size of remaining length is relevant with the centre distance of beam tube and resultant pitch, and the optical fiber in beam tube is slightly more longer than the length of beam tube, different cable configurations, optical fiber in beam tube more than long also different.When optical cable is in high hydrogen molecule environment, or cable material fiber optic cable manufacture, deposit with operational process in constantly separate out hydrogen, these hydrogen molecules are spread to fiber cores district by optical fiber periphery gradually, easily there is hydrogen loss, hydrogen loss causes fibre loss to increase, severe patient accelerates the static fatigue of optical fiber, finally makes fibercuts, shortens the serviceable life of optical fiber.The low temperature cone penetration of optical fiber ointment is little, and low temperature added losses can be caused to increase, and hydrogen-separating quantity height can cause fibre loss pass in time and increase gradually " hydrogen loss ".
Utility model content
The purpose of this utility model is to provide a kind of optical fiber logging cable, corrosion-resistant, the life-span is long, can offset the shearing force of optical cable reeling, when launching, prevent optical fiber to be subject to microbending.
In order to reach above-mentioned purpose, the utility model have employed following technical scheme, a kind of optical fiber logging cable, comprises the optical fiber of outer armour and outer armour inside, described outer armour is stainless steel armor, and described optical fiber is peripheral and stainless steel armor inside is also provided with stainless steel bushing pipe.
Polyurethane adhesive is filled with between described stainless steel bushing pipe and stainless steel armor.
Greasy for preventing water is filled with between described optical fiber and stainless steel bushing pipe.
Described stainless steel armor diameter is 6.35mm, and described stainless steel liner diameter is 2.4mm.
Described stainless steel bushing pipe inside and outside wall all adopts low hydrogen penetration material to apply, and outside this coating, plate the hard anti-scratch material of one deck.
Compared to prior art, the utility model has following beneficial effect:
The utility model comprises sandwich layer and outer jacket, and sandwich layer comprises internal lining pipe, and there is one or more fibre core the inside, has padded coaming to fill between outer jacket and sandwich layer, and this propping material can make interior pipe keep placed in the middle, and make two-layer between there is no relative motion.For the infringement of hydrogen is down to minimum, oil well test optical cable inner tube adopts the coating of low hydrogen penetration material, and outside this coating, plate the hard anti-scratch material of one deck, ensures the integrality of coating.Inner tube has squeezed liberation of hydrogen packing material greasy for preventing water simultaneously, and this material has very strong viscosity, can offset the shearing force of optical cable when winding, expansion, prevent optical fiber to be subject to microbending.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of optical fiber logging cable of the present utility model.
In figure, 1, stainless steel armor, 2, polyurethane adhesive, 3, stainless steel bushing pipe, 4, greasy for preventing water; 5, optical fiber.
Embodiment
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides with reference to the use with explanation, is not used for being limited the utility model.
According to Fig. 1, a kind of optical fiber logging cable, comprises the optical fiber 5 of outer armour and outer armour inside, and described outer armour is stainless steel armor 1, and described optical fiber is peripheral and stainless steel armor inside is also provided with stainless steel bushing pipe 3.Polyurethane adhesive 2 is filled with between described stainless steel bushing pipe and stainless steel armor.Greasy for preventing water 4 is filled with between described optical fiber and stainless steel bushing pipe.Described stainless steel armor diameter is 6.35mm.Described stainless steel liner diameter is 2.4mm.
This cable is made up of optical fiber, greasy for preventing water, stainless steel bushing pipe, polyurethane adhesive and the armoured layer of stainless steel etc. toward interior successively from outer; this well logging optical cable manufacturing procedure adopts the method for fractional steps; optical cable production line is first utilized to complete the prefabricated of inner armor optical cable; with pulling method into, prefabricated inner armor optical cable is penetrated in outer protective hair tubule again, last injecting glue fixedly completes the manufacture of special downhole testing optical cable.
The foregoing is only preferred embodiment of the present utility model, be not used to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
