Adsorption of Calcium and Magnesium Ions and Thickening Effect
Abstract
Waste water rich in high-concentration Ca2+、Mg2+ in a block of Daqing Oilfield, the influence of Ca2+and Mg2+ on polymer solution viscosity is considered. To use of sodium humate solution which compound by turf and NaOH complexed Ca2+ and Mg2+, reduced the impact of Ca2+ and Mg2+ on the polymer solution viscosity, so reached oilfield reinjection water viscosity standards. Research show that polymer solution viscosity lossed seriously when Ca2+ and Mg2+ content in 0 ~ 200mg / L, viscosity loss rate reached maximum 63.2% and 70.7%, respectively. The adsorption ratio of Ca2+ reached 77.50% when amount of sodium humate solution were 8mL. Similarly, the adsorption ratio of Mg2+ reached 83.60% when amount of sodium humate solution were 6mL. This indicated that sodium humate have great adsorption to Ca2+ and Mg2+. Indoor experimental results confirmed the feasibility of using sodium humate complexed Ca2+ and Mg2+ to prevent viscosity of polymer solution reduced, and provides a reference for the field test.
