The load-bearing detection cable has the advantages of lightness, high strength and long service lifetime, and can work for a long time in severe environment in oil wells.
Description
Technical field
The utility model relates to a kind of charge bearing detecting cable.
Background technology
In oil exploitation, traditional charge bearing detecting cable refers to that mainly those are bearing the double wire armor cable that carries out down-hole oil field detection under mechanical load (sash weight the adds the cable deadweight) situation, its function has well logging, perforation etc., so charge bearing detecting cable requires to have big length and high-intensity characteristic usually.Charge bearing detecting cable is termed meaning oil worker's eyes in petroleum industry, just can find out underground by it is oil or gas, and can measure technical parameters such as well temperature, well pressure and hole deviation, and hence one can see that for the importance of its use, and consumption is also bigger.
Oil well can be divided into shallow well, deep-well and ultradeep well usually according to well depth, and general well depth 2200～3500m is shallow well, downhole temperature≤100 ℃; Well depth 3500～5500m is deep-well, and following temperature≤150 ℃; Well depth 5500～7000m is ultradeep well, about 200 ℃ of downhole temperatures.
When charge bearing detecting cable is logged well the testing time of general a bite well not long, in 2,3 hours, can test and finish.But because poor, the service condition harshness of environment for use, 1 cable generally can only be surveyed about 300 mouthfuls of wells, and therefore, charge bearing detecting cable is the easily-consumed products in the oil field, and the replacement cycle is short and frequent, so use amount is big.
From the production technology angle, the key technology that the charge bearing detecting cable of traditional double wire armor is produced and technology are the control problem of double wire armor technology, the cover wire that its specification requirement is pulled down from cable should be able to remain on original spiral-shaped, not loose on the cable.This just requires in production process, and outer armouring wire should carry out predeformation before production, the technology that will carry out pre-stretching to whole cable after armouring is finished.Though handle through pre-stretching when employed traditional charge bearing detecting cable dispatches from the factory at present, eliminated the prestressing force of two steel wires, but still understood some residue stress.In addition, repeatedly use the steel wire wear of back cable outer layer serious, steel wire is semicircular by original round wire wearing and tearing, in addition down-hole high temperature pressure corrosion oil gas, H
2S etc. shrink the outside diameter of cable to the corrosion of cable outer layer steel wire, and fracture generation card well phenomenon takes place cover wire when serious, thereby causes expensive detection instrument to be difficult to take out, and causes scrapping of cable even scrapping of whole mouthful of oil well.
