Optimization and exploration of electromagnetic anti-scale technology
摘要
Abstract
As a new physical method,electromagnetic descaling can promote the dissolution of calcium carbonate in water or cause a change in the crystal structure of calcium carbonate,thereby inhibiting the formation of calcium carbonate precipitation.In order to investigate the changes in the scale inhibition performance of the electromagnetic anti-scale device under different process parameters,and verify the optimal process conditions of the electromagnetic anti-scale device within the research range using response surface analysis,the critical conductivity value of the simulated water sample was evaluated using the conductivity method as the scale inhibition rate evaluation standard.The influence of different process parameters on the critical conductivity value of the simulated water sample was examined.The results show that when the electromagnetic field voltage is 12 V,the frequency is 54 Hz,the action time is 0.7 h and the temperature is 31 ℃,the critical conductivity value of the simulated water sample is 1 662 μS/cm.The critical conductivity value of the simulated water sample is increased by 229 μS/cm compared with water sample without electromagnetic scale inhibition treatment.This shows that the application of the electromagnetic anti-scale device in the oilfield water injection development process has good scale inhibition performance.关键词
