Abstract
The utility model provides a loaded exploration cable with high-temperature resistance and high water-pressure resistance, which consists of a conducting core, an insulating layer, an internal armour layer and an external armour layer. The insulating layer is arranged between one or a plurality of conducting cores and a stainless steel sheathing layer. The internal armour layer adopting a mode of steel wire right-hand armouring and the external armour layer which is located outside the internal armour layer and adopts a mode of steel wire left-hand armouring are arranged outside the stainless steel sheathing layer. The conducting core is a copper wire of which the cross section takes a circle shape. The stainless steel sheathing layer is a sealing steel tube. The loaded exploration cable of the utility model is mainly used for operations of oil field well logging, etc.
Description
Technical field:
The utility model relates to cable, more particularly relates to a kind of high temperature resistant high water pressure resistant charge bearing detecting cable that is used for operations such as oil reservoir logging.
Background technology:
Oil drilling is constantly deepened, and to the length requirement of charge bearing detecting cable, by 5～6 kms in past, transfers 7～8 kms to, even longer.Along with the intensification of well depth, subsurface environment is harsh more, and this just requires high temperature resistant, the high water pressure resistant index of cable to improve.200～260 ℃ of the heatproofs of prior art, the cable of withstand voltage 100MPa can not satisfy the requirement of well logging market to cable fully.
Summary of the invention:
The purpose of this utility model provides a kind of high temperature resistant high water pressure resistant charge bearing detecting cable that can use under the high temperature of 500 ℃ and 350MPa, hyperbaric environment.
The purpose of this utility model can realize by following technical measures:
This is high temperature resistant high water pressure resistant charge bearing detecting cable is by conductor cores, insulating barrier, interior armor layer and outer armor layer constitute, one or more conductor cores and stainless steel sheath interlayer are provided with insulating barrier, and the outer armor layer of interior armor layer that adopts steel wire dextrad dress armour and the employing steel wire left-hand dress armour that is positioned at the armor layer outside is arranged outside the stainless steel sheath layer.
The purpose of this utility model also can realize by following technical measures:
Described conductor cores is that a cross section is circular copper cash; Described stainless steel sheath layer is a sealed steel pipe.
High temperature resistant high water pressure resistant charge bearing detecting cable described in the utility model is by one or more conductor cores and the charge bearing detecting cable that outwards constitutes for insulating barrier, stainless steel sheath layer, interior armor layer, outer armor layer successively.After tested, can to adapt to down-hole, oil field 8 kms and temperature be that 500 ℃, pressure are that the harshness well logging environment of the high temperature of 350MPa, high hydraulic pressure uses to the utility model.
Description of drawings:
Fig. 1 is that the conductor cores of the utility model embodiment is one a circular structure schematic diagram.
