Firstly, polyacrylamide with 26 million molecular weight was compounded in lab through establishing optimum compounding initiator proportionality of 1:1. 3 and mass concentration of 170 mgL^(-1), temperature of 10 ℃, acrylamide mass percentage of 25%, electrical conductivity of 3.6 μSm^(-1) and pH value of 6.57. The salt-resistance, thermal endurance and shear-resistance of polyacrylamide could be enhanced b introducing sulfonic acid group or styrene sulfonate group or drawing the two groups above at the same time. Secondly, chelator HEDP, bactericide isoquinoline ketone and oxygen scavenger thiourea were optimized to improve the compatibility of polyacrylamide and formation water.
