摘　　要：国内稠化剂产品多表现出受剪切影响大、酸液增黏能力弱、现场配制时间长等缺点。为了提高酸液黏度，降低酸液在地层中的反应速度。采用反相乳液聚合的方法合成了分子量在（800～1100）×10^4的酸液稠化剂TP—1。性能评价试验结果显示，稠化剂TP—1的酸溶时间小于10min，具有很好的溶解能力；TP—1对酸液的增黏作用明显，（4％TP-1＋20％HCl）酸溶液90℃下表观黏度达到46mPa·s，120℃下表现黏度27mPa·s。同时TP-1表现出较强的耐剪切能力和良好的配制稳定性，有利于酸化措施效果的提高。most domestic densifier expressed greatly affected by shearing,the glutinous of acidizing fluid is poor,the time cost of making up is too long.In order to advance the viscosity of acidizing fluid and decrease the reaction speed of acidizing fluid in oil formation,adopt the method of opposite phase emulsim polymerization synthetised an acidizing fluid densifier,it called TP-1,its molecular weight is(800～1100)×10.laboratory findings discovers the acid dissolving time of TP-1 is smaller than 10 min,its dissolving capacity is very good;its glutinous is obvious,in the temperature of 90℃,the apparent viscosity of acid solution attains 46 mPa·s,and in the temperature of 120℃,it is 27 mPa·s.At the same time,TP-1 expressed strong resisting shearing and favorable manufacture stability,it advanced the effectiveness of acidify.
