Technical Field
The invention relates to the technical field of increasing the overcurrent capacity of a T-cable suspension device, in particular to a high-pressure wellhead T-cable suspension device with an overcurrent side channel.
Background
The wax deposition of oil well is a long-standing problem in the development process of oil field, when crude oil is pumped from underground to ground, the temperature of crude oil is gradually reduced due to the escape and expansion of dissolved gas, the wax is crystallized and separated out from crude oil according to the molecular weight, and then deposited on the inner wall of oil pipe, so that the oil well is narrowed, the yield of oil well is reduced, and when serious, the oil pipe is blocked, and the oil well is stopped.
At present, heat tracing is carried out by adopting a heat tracing cable, so that the phenomenon of wax precipitation is avoided, and the temperature in an oil well is prevented from being too low. The hanger is a hanger that combines the heat trace cable with the oil recovery pipe. However, the current hanger has weak overcurrent capability and does not have the capability of producing oil gas while hanging cables.
