Problems solved by technology

[0003] At present, most of the top drive cables used in oil fields are rubber cable products. This type of product mainly meets the softness requirements, but its tensile performance, oil resistance, and wear resistance are obviously insufficient. The service life of the cable is often not more than 6 months. Work progress and increased changeover costs
In addition, although there is rubber filling in the gap of the cable core in the conventional rubber cable, it still cannot guarantee the tightness of the cable structure, and

Embodiment Construction

[0035] see figure 1 , figure 2 , image 3 .

[0036] The cable core 10 of this cable is sleeved in the casing, and the head of the cable core 10 protrudes from the casing, and the protruding cable core head is covered with a metal anti-scratch net 11 . The main body of the casing is a hose 8, which can be selected from one of oil-resistant rubber hose, oil-resistant rubber hose with cloth clamp, oil-resistant rubber hose with spring steel wire, oil-resistant rubber hose with cloth belt steel wire, preferably oil-resistant rubber hose with cloth belt steel wire. Tube. The end of the flexible pipe 8 is equipped with a metal pipe head, both ends of the power cable are equipped with a metal pipe head, and the control cable is only equipped with a metal pipe head at the hanging end. The metal pipe head is fixedly connected with the hose 8 as a whole. The metal pipe head is composed of a flange 5, an inner fastener 6 and an outer fastener 7. It is made of stainless steel. The i...

Abstract

The invention provides a special cable for top drive drilling and a manufacture method thereof. The cable comprises a cable core, wherein the cable core is sleeved in a sleeve, a main body of the sleeve is a soft tube, one end or two ends of the soft tube is or are provided with a metal tube head(s) which is or are fixedly connected with the soft tube into a whole, the head part of the cable core extends out of the metal tube head; a plurality of segments of sealing glue are filled in the sleeve, the cable core is fixed in the sleeve; and a hanging ring is arranged on the metal tube head, and used for hanging the cable on a derrick. The normal use environment temperature of the cable is -40 DEG C-+110 DEG C, the cable has better torsion resistance and bendability, is more suitable for being used in moving and dragging conditions, and can completely adapt to the special use environment in an oil field. Especially, the cable core is packaged in the sleeve, the gravity of the cable is borne by the sleeve, and the drawing force of the cable core per se is little, thus the cable is not easily damaged, the service life is greatly prolonged, and the probability of drilling stop due to the cable is greatly reduced.

Description

technical field [0001] The invention relates to a cable and a manufacturing method thereof, in particular to a cable used for oil and natural gas top drive drilling devices and a manufacturing method thereof. Background technique [0002] Top drive drilling is a new drilling technology in the contemporary oil and gas industry. Its driving motor is arranged on the derrick, and it must move up and down with the drilling tool during work. Correspondingly, the power cable and control cable of the motor will also follow Moving upstream and downstream requires cables to have excellent flexibility; oil and natural gas will corrode cable materials, and cables are required to have oil resistance and corrosion resistance; oil and gas fields are widely distributed, including land, ocean, tropical regions, and alpine regions region, which in turn requires cables to be weather resistant. [0003] At present, most of the top drive cables used in oil fields are rubber cable products. This...
