摘　　要：在室内研制了一种可供不同温度油藏调剖用的HPAM/wy-316乳酸铬凝胶体系。考察了聚合物浓度、wy-316乳酸铬交联剂浓度、温度以及pH值对成胶性能的影响。确定了HPAM/wy-316乳酸铬体系的最佳形成条件:HPAM聚合物1000～1500mg/L;wy-316乳酸铬系列交联剂(以Cr3+计)浓度600～1200mg/L;体系pH值6～9;使用温度40℃～60℃。通过调节pH可以实现HPAM/wy-316乳酸铬凝胶体系成胶时间可控,凝胶强度可调。可以耐受较宽范围的温度和PH条件,能适应不同交联时间的要求。A HPAM/ wy-316 Chrominum-Organic crosslinker Gel system? was prepared with HPAM as chrominum-organic as crosslinker.Under different conditions,this gel system was suitable to wide temperature range and PH range.The effects of various factors on the gelation: Chrominum-Organic crosslinker adding amount,HPAM adding amount,PH of system and temperature on the performances of polymer gel system were evaluated.The optimum formulation was determined as follows: HPAM adding amount 1000～1500mg/L,wy-316 Chrominum-Organic crosslinker adding amount 600～1200mg/L,the tempreture range is 40℃～60℃,PH=6～9.
