Novel oil well electromagnetic paraffin remover

Abstract

The invention provides a novel oil well electromagnetic paraffin remover. The novel oil well electromagnetic paraffin remover comprises a steel pipe; flange end covers are mounted at the left end andthe right end of the steel pipe correspondingly; the outer wall of the steel pipe is sleeved with a protective shell; a plurality of sets of inductance coils are evenly distributed on the outer wall of the steel pipe covered by the protective shell in a wound mode; waterproof fillers are arranged between the inductance coils and the inner wall of the protective shell; thermistors are arranged in the inductance coils; and protective baffle rings are mounted at openings of the left end and the right end of the protective shell in a sleeving mode. According to the electromagnetic induction principle, the novel oil well electromagnetic paraffin remover intends to adopt the mode that a high-frequency current is generated by an electronic circuit, a high-frequency electromagnetic field with thecertain strength is generated by the inductance coils, and when alternating magnetic flux acts on the steel pipe, the extremely-strong eddy current and heat effects are quickly generated in the steelpipe; and in addition, the alternating magnetic flux is further used for directly heating oil through the outer sleeve steel pipe, thus the temperature in the pipe is higher than the crystallization temperature of paraffin in the crude oil, and the paraffin removing effect is achieved accordingly.

Description

technical field [0001] The invention relates to a wax removal and scale removal device for oil transportation, in particular to a novel electromagnetic wax remover for oil wells. Background technique [0002] There are a lot of crude oil reserves in our country. In the process of oilfield development, as the crude oil is lifted from the bottom of the oil well to the surface, the paraffin dissolved in the crude oil will be separated out with the decrease of temperature and pressure and the precipitation of natural gas. Colloid and asphalt components will precipitate in crystal state and condense on the wall of tubing sucker rod, causing wax deposition in oil production wells and affecting normal production. How to remove wax deposits in oilfields, increase oil production and reduce oil production costs has been an urgent problem to be solved in the oil production process for many years. [0003] The problem of wax deposition in oil wells has become one of the most urgent tec...
