Simple oil well wax removing device

Abstract

The invention relates to the technical field of oil exploitation, and particularly relates to a simple oil well wax removing device. The simple oil well wax removing device is composed of a ground control box, a first cable, a first control valve, a second cable, a second control valve, a thickness sensor, a mechanical wax removing module, a chemical wax removing and preventing module, a closed protective shell, a rotating shaft, a fixed tool support, an annular dosing box, a hole, an electric elevator, a mooring rope, a fixed pulley, a tool handle, a tool bit and a thread. The mechanical wax removing module and the chemical wax removing and preventing module are distributed on the outer wall of an oil pipe and connected with the ground control box through the first cable. The simple oil well wax removing device is mainly used for removing wax, and the underground condition is rapidly recognized through the thickness sensor; in the wax removing process, a wax layer can be softened through chemical wax removing and preventing, mechanical wax removing is more efficient, and the tool bit is protected. The two wax removing and preventing modes are mutually supplemented and matched, the wax removing and preventing efficiency is improved, operation is simplified, and the simple oil well wax removing device is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to a simple oil well wax removal device. Background technique [0002] In the process of crude oil extraction, due to the decrease of temperature and pressure, the solubility of crude oil to wax is reduced, so paraffin will crystallize out from crude oil. On the one hand, wax deposition will lead to clogging of tubing, increase flow resistance, reduce delivery efficiency, and lead to a decrease in production; Affect the working life of the sucker rod. Therefore, wax removal and wax prevention are a topic that oilfield production must pay attention to. At present, there are many wax removal methods, such as electric heating wax removal, strong magnetic wax removal, oil pipe lining coating wax removal, mechanical wax removal, etc., but each method has its own defects. Economical, strong magnetic anti-wax requires complex equipment and difficult management, hot oil wa...
