Petroleum and gas exploitation wellhead heating equipment

Abstract

The invention discloses petroleum and gas exploitation wellhead heating equipment. The petroleum and gas exploitation wellhead heating equipment structurally comprises a petroleum connecting pipe, a wellhead heater, a wax-removing flow-aid device, a petroleum drain pipe, a front supporting frame and a rear fixing frame; the right side of the petroleum connecting pipe and the center of the left side of the wellhead heater are connected in an electro-welded mode; the left side of the petroleum drain pipe is mounted in the right side of the wax-removing flow-aid device in an embedded mode; the front supporting frame is mounted on the left side of the rear fixing frame; the right side of the wellhead heater is located on the left side of the wax-removing flow-aid device, and the right side ofthe wellhead heater and the left side of the wax-removing flow-aid device are welded; and the lower side of the petroleum drain pipe and the upper end of the rear fixing frame are welded and located on the upper right corner of the front supporting frame. According to the petroleum and gas exploitation wellhead heating equipment, by connecting petroleum in, the petroleum pushes a starting device to mince oil wax of the petroleum, thus temperature increasing is facilitated, the oil wax is melted rapidly, viscosity is reduced, and pipeline blocking is prevented; and flowing of the petroleum is accelerated through an internal petroleum flow-aid rod, the situation that flowing is excessively slow, and consequently the carbonization coking phenomenon is generated through heating is avoided, andthe conveying condition of heavy petroleum is improved.

Description

technical field [0001] The invention relates to wellhead heating equipment for oil and gas exploitation, which belongs to the field of heating equipment. Background technique [0002] The working principle of heating equipment is to install a primary coil with more turns and a secondary coil with less turns on the same iron core, and the voltage ratio between input and output is equal to the ratio of coil turns, while the energy remains unchanged. . [0003] However, a kind of wellhead heating equipment for oil and gas production in the prior art is mainly used for heat-tracing transmission of crude oil in high-condensation thick oil wells and oil well oil gathering pipelines and oil pipelines in alpine regions. Although the oil can be heated to facilitate transportation, the oil The flow aid of the oil is poor, resulting in a slow flow rate of viscous oil inside the heater, which will cause carbonization and coking of the oil during excessive heating, which will affect oil...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a wellhead heating device for oil and gas production to solve the problem of the oil and gas production wellhead heating device in the prior art. And the crude oil heat tracing transmission of the oil pipeline, although the oil can be heated to facilitate transportation, but the flow aid of the oil is poor, resulting in a slow flow rate of the viscous oil inside the heater, so that the excessive heating of the oil will lead to carbonization and coking, which will affect the oil. Transportation, and for oil in alpine regions, it is easy to wax, and heating can remove oil wax on the surface, but the effect on internal wax removal is poor, which may lead to the problem of pipeline blockage during oil transportation
