Abstract

The invention discloses a wellhead heating assembly comprising a fuel gas generator, a fuel gas pipe, an oil outlet pipe, a heating sleeve, a heating coiled pipe, a tail gas pipe, a heat exchange coiled pipe and a circulating pipe. The fuel gas generator is connected with the fuel gas pipe, the tail gas pipe is arranged on the fuel gas generator, and the heat exchange coiled pipe is spirally wound on the tail gas pipe. The heating sleeve is arranged on the outer side of the oil outlet pipe, and the heating coiled pipe is arranged in the heating sleeve. The heat exchange coiled pipe and the heating coiled pipe are connected through the circulating pipe. The fuel gas pipe is connected with the oil outlet pipe. The wellhead heating assembly further comprises a circulating pump arranged on the circulating pipe. The wellhead heating assembly is simple in structure, convenient to use, high in safety, good in heating effect, energy saving and emission reducing.

Description

technical field [0001] The invention relates to the technical field of oil exploitation, and more specifically relates to a wellhead heating assembly. Background technique [0002] In the process of oil extraction, the temperature of crude oil gradually decreases due to the influence of formation and air temperature when it is pumped out of the ground. Especially in winter, the temperature of crude oil decreases faster during the transmission process in the pipeline. Waxing is easy to occur on the surface, which leads to the reduction of oil transportation efficiency. In order to prevent waxing, heating furnaces are generally used in oil mining fields to heat wellhead oil pipelines. The heating furnaces are mainly water jacket heating furnaces, water jacket heating furnaces A coil is added to the water jacket, and the water in the water jacket is heated to transfer heat to the oil in the coil. This heating furnace is not suitable for oil wells with low output and intermitten...
