Abstract
The utility model relates to a be applicable to high temperature complex construction well logging cable, its characteristics mainly include: lag, outer armour layer, polymer layer, interior armour layer, lapping layer, filler, iron shielded layer, core insulation layer, electrically conductive cable core, protective layer, fine cream, fiber optic cable core. The outermost lag of cable have wear -resisting, prevent that hydrogen sulfide, acid -base thing corrode and characteristics such as high temperature resistant, can improve the cable life -span and weaken shaft bottom high temperature influence. Bearing and full shielding effect are played to whole cable in the armour layer in outer armour layer of minor diameter and the major diameter. Polymer layer separates outer armour layer and interior armour layer and lock inside and outside armour layer in corresponding fixed position, can reduce sliding friction between the inside and outside armour layer, the local distortion of cable and maintain the cable balance. The cable is inside have six can the fast transferring electric energy electrically conductive cable core and a transmission well logging information parameter's major diameter fiber optic cable core.

Description
Technical field
This utility model relates to petroleum well logging technology field, is specifically related to one and is applicable to high temperature complex structural well logging cable.
Background technology
Along with oil gas energy exploration development technique develops rapidly, the degree of depth of institute's drilling well is continuously increased, well construction and ground environment more
Complicated and formation temperature constantly raises, and the well logging causing traditional armoured logging cable to be difficult to meet high temperature complex structural well uses
Requirement, has the disadvantages that when traditional armoured logging cable is applied to high temperature complex structural well
1) traditional armoured logging cable is prone to be affected (particularly with geothermal well) by stratum high-temperature, causes the well logging of downhole instrument
Signal interferes and decays, the accuracy of impact well logging result and reduction cable life；2) the outer armour of traditional armoured logging cable
Layer appearance does not has protective jacket, when logging well at the Acidity of Aikalinity stratum such as sulfide hydrogen and extended horizontal well, cable subject to corrosion and
The borehole wall weares and teares, and corrodes and weares and teares and all can reduce cable tensile strength and life-span；3) traditional armoured logging cable unit length proportion
When relatively big, cable does not bears load, tension stress is relatively big, thus causes cable tensile strength relatively low；4) traditional armouring is surveyed
In well cable, external armor layer contacts with each other, and when cable tension, between interior external armor layer, sliding friction is relatively big and cable torsional forces is uneven,
Cable is prone to produce local deformation.
Analyzing based on above, this utility model Patent design one is applicable to high temperature complex structural well logging cable, it is intended to solve
The shortcoming that above-mentioned tradition armoured logging cable exists, to ensure that logging cable can be effectively and rapidly by high temperature complex structural well stratum
Information is accurately transferred to ground and improves cable tensile strength and extend cable life.
Utility model content
The purpose of this utility model is to provide one to be applicable to high temperature labyrinth borehole logging tool electricity for the well logging of high temperature complex structural well
Cable, to improve logging signal accuracy, cable tensile strength and to extend cable life.
In order to achieve the above object, this utility model adopts the following technical scheme that:
One is applicable to high temperature complex structural well logging cable mainly by protective jacket, external armor layer, polymeric layer, internal armored layer, wrapped
Layer, implant, metal screen layer, cable core insulating barrier, conductive cable core, protective layer, fine cream, optic fibre core composition.
Cable has six conductive cable core that can quickly transmit electric energy and the large-diameter fibre-optical cable core of a transmission well logging information parameter,
Large-diameter fibre-optical cable core is conducive to logging signal accurately and quickly to transmit.
This utility model logging cable design major diameter internal armored layer and minor diameter external armor layer, this kind of design largely can reduce survey
Tension stress when well cable self unit length proportion and logging cable do not bear load, such that it is able to improve the tension of logging cable
Intensity.
The protective jacket being wrapped in external armor layer outer surface has high temperature resistance, hydrogen sulfide wear-resistant, anti-and the corrodible property of soda acid thing, can
Logging cable is transmitted effect of signals, the external armor layer that is made up of wire material of protection away from soda acids such as hydrogen sulfide weakening stratum high-temperature
Property material corrosion and prevent external armor layer and wall friction, thus improve working life and the tensile strength of logging cable.
External armor layer and internal armored layer are separated and interior external armor layer are locked in respective anchor site by polymeric layer, can be greatly lowered
Sliding friction between interior external armor layer, cable bird caging deformation and maintenance cable balance.
