Description

technical field [0001] The invention relates to an anti-wax device used in oil fields, in particular to an electromagnetic anti-wax device based on a single-chip microcomputer, and belongs to the technical field of automatic wax removal in oil fields. Background technique [0002] When the oil field is exploited, the wax is separated and precipitated from the oil, and the continuous deposition of the wax will lead to blockage of the oil-producing layers, oil wells and oil pipelines, resulting in a decrease in production, and even shutdown of production, which will bring great trouble to production. Waxing in oil wells is one of the outstanding problems that affect the high and stable production of oil wells. Seeking reasonable methods to solve the problems encountered in oil and gas production has become an urgent problem in oilfield exploitation. [0003] At present, the commonly used wax removal methods mainly include mechanical wax removal, thermal wax removal, and chemic...
