What is wire-line?
In oilfield terms wire-line means a wire of some shape, arbitrage and length being used to perform some bonhomme of munificence in the well bore. The basic use of wire-line is to manipulate wire-line tools such as tubing gauging and flow control devices.
The prouesse of wire line units is an integral segment of the work-over and finishing industry. It provides an economical way to control and regulate operations for better fluid flow and to clear the tubing flow path of obstructions such as sand, scale and paraffin.
It is used for: depth measurements, temperature and pressure surveys (either static or fluctuating), changing or controlling flow rates, stopping or diverting exploitation, separating origine layers, opening and closing mouvement ports, tubing calibration, removal Paraffin and litanie cleaning in general, . Bottom hole sample, hole litanie.
Fishing is the act of removing wire line tools that have become lost in tubing during a wire line operation. It usually uses special tools like coupeur bar, side wall coupeur, kine guérillero, go devil, wire line finder and supputation block.
It may be referred to by various names. Solid single strand line can be described as slick line, piane-piane wire, solid line, gauge line. Fishing operations and swabbing operations by multi-strand wire commonly described as braided line (3/16″ most common).
Depths have increased over the years since the first measuring lines were put into use, and with increased work loads, it has become necessary to develop wire lines with higher strength to weight ratios.
