Synthesis of Xanthan Gum/AMPS/Bentonite Composite Water Plugging Agent for Oil Field
摘要
Abstract
Xanthan gum(XG)/2 - acrylamido - 2 - methylpropanesulfonic acid (AMPS)/bentonite composite water plugging agent for oil field was synthesized by aqueous solution polymerization. Effect of the amount of AMPS, bentonite, crosslinking agent and initiator on waterabsorption capacity of water shutoff agent were investigated. Waterabsorbency and water retaining rate of the water shutoff agent at different temperature were tested. NaCl concentration on waterabsorption capacity of water shutoff agent were researched. The results show that the optimum process conditions were obtained as follows; ω(bentonite) is 15%, ω( AMPS) is 3% , ω(crosslinking agent) is 2%, ω(initiator) is 2. 5% , and reaction temperature is 40 ℃ for 4 hours. Under the optimum technological conditions, with the environmental temperature of 20 ℃ , waterabsorbency for deionized water and 0. 9% NaCl solution of the water plugging agent for oil field are respectively 1 677 g/g, 165 g/g. With the environmental temperature of 80 ℃, waterabsorbency for deionized water of the water plugging agent for oil field are respectively 1 590 g/g, within 12 h can hold water over 20%, which possessed a good thermal stability and salt tolerance.关键词
