Study On Anti Fouling Technology Of Oil Field Water System Pipeline By Using Electric Absorption Method

Nowadays, with the water-flood development of high water cut oilfield, the sewage contained a large number of complex components makes the production system of treatment plants fouling and clogging severely. The study on the cause of scaling in oilfield water system and effective anti-scaling technology is of great importance to increase water treatment efficiency, improve equipment life and reduce economic losses.The article first analyzes the collected water sample and scale samples, finding the main components of the scale, namely calcium carbonate. Then CFD method is adopted by using FLUENT software to simulate the scaling factors, which mainly contain pipe inlet velocity,temperature and Ion concentration, rationally reducing deposition rate.Based on the research, an anti-scaling device is designed keeping the inlet flow rate and temperature fixed. The device adopts a new electric adsorption anti-scaling technology.Parameters are best selected of the voltage, the distance between the electrode and material by simple test, determining the specific configuration of the electrical adsorption module and keeping sealing and insulating properties. The field craft for electric adsorption device has been drawn up. By analyzing the component of water between before and after the adsorption and the coupon test, the anti-scaling effectiveness is evaluated. It shows that, the electric adsorption device can significantly reduce equipment scaling rate, thus prolonging cleaning cycle.In a word, Study on anti fouling technology of oil field water system pipeline by using electric absorption method has great value in solving oil field scaling problems.
