Description
Technical Field
The utility model relates to the field of top drive cable structures, in particular to a top drive cable of a liquid cooling oil drilling platform.
Background
With the advancement of industrialization, the world energy problem enters deep ploughing areas. The mature exploitation technology of traditional petrochemical energy source is more toward deep water bottleneck region. The oil drilling platform has one cable, which is a top drive cable, and the harsh working environment of the cable has higher requirements on the performance of the cable, so that the exploitation power of the oil drilling platform is always limited. The working environment requires the cable to have the characteristics of slurry resistance, oil resistance, high current carrying capacity, frequent movement and the like. The characteristics of slurry resistance, oil resistance and frequent movement are relatively easy to achieve, and the high current carrying capacity becomes the highest requirement for limiting the cable.
Because the heating power of the cable is increasing with the increase of the current-carrying capacity of the cable, the cable will heat up during operation, and the temperature of the cable will become very high with the accumulation of time, typically exceeding 100 ℃. At such high temperatures, the insulation of the cable increases ageing. Resulting in a very short lifetime of the cable. To solve the problem of heating up the cable, the general idea is to increase the section of the cable, that is, to increase the outer diameter of the cable, so as to reduce the heating resistance of the cable without ensuring the power. However, the outer diameter of the cable is severely limited by the application. During drilling, the smaller the outer diameter of the cable, the better the construction site expects. So this method is not feasible. The second general idea is to increase the operation voltage of the cable and reduce the transmission current under the condition of ensuring the transmission power, thereby achieving the purpose of cooling. However, environmental safety issues force an unlimited increase in device voltage, currently licensed in the field at 2000V. So this approach is not feasible.
So that only the high current carrying condition of the same-section cable remains. However, high current carrying, brings about a rapid heating of the cable. If the heating can be controlled, the problem can be solved. If the generated heat can be taken away in time, the temperature rise can be controlled, and the heat is taken away and is taken away from the inside of the cable. Because the cable "fails" because the insulation inside is aged.
