Description

technical field [0001] The invention belongs to the technical field of oil recovery in oilfields, and in particular relates to a rapid evaluation device and evaluation method for wax removal rate of on-site wax remover and anti-wax agent. Background technique [0002] Wax deposition is common in oil wells. Wax deposition will block oil outlet channels, increase wellhead back pressure, reduce oil well production, and increase oil well load. In order to maintain the normal production of oil wells, the wax removal and control agent is mainly used for wax removal and control at present. Due to the wide variety of paraffin removers and inhibitors on the market, the effects of wax removers and inhibitors with different formulations on oil wells vary greatly. In order to evaluate the wax remover with the best wax and inhibitor effect, it is necessary to carry out wax control in the laboratory in advance. Rate test, that is, to measure the amount of wax deposition in oil samples of...
