Abstract


The scaling problem of silicon in the heavy oil production of Shengli Oilfield will seriously affect the normal production and production. According to SYT 5523-2006 oilfield water analysis method, the ions in the water samples collected by each water treatment unit were analyzed, and it was found that the content of metasilicic acid in the high-temperature separation water was relatively high, so the effect of four kinds of desilication agents was studied in this paper. It is found that the effect of desilication agent is the best. Magnesium agent is selected as desilication agent. Through the orthogonal experiment of three factors designed by SPSS software, the factors influencing desilication effect are investigated. Through the analysis of SPSS, it is found that the effect of temperature on the experimental results is not significant. After comprehensive investigation, it is concluded that the effect of desilication is the best when the dosage of agent is 400mg/L, and the effect of desilication is the best when the pH is 10. According to the experimental data, it can be seen that the effect of desilication is the best when the dosage is 400mg/L The removal rate of silicon can reach more than 90%.
