主　　题：Scale inhibitor squeeze Inhibitor retention Surface poisoning Adsorption Squeeze life 

摘      要：The mechanistic understanding of the reactions that govern the inhibitor retention and release,modeling,and the state-ofthe-art innovation in squeeze treatment are *** retention and release are governed by(1)the amount of calcite that can dissolve prior to inhibitor-induced surface poisoning;(2)calcite surface poisoning after^20 molecular layers of surface coverage by the adsorbed inhibitors to retard further calcite dissolution;(3)less base,CO3^2-,is released into the aqueous solution;(4)formation of the more acidic inhibitor precipitates;(5)phase transformation and maturation of the more acidic inhibitor precipitates;and(6)dissolution of the less soluble crystalline inhibitor *** trend to advance squeeze technologies is through(1)enhancing scale inhibitor retention,(2)optimizing the delivery of scale inhibitors to the target zone,and(3)improving monitoring ***,a prototype yardstick for measuring the squeeze performance is used to compare the squeeze life of 17 actual squeeze *** though the various squeeze treatments appear to be *** published squeeze durations can be rated based on the normalized squeeze life per unit mass of inhibitors.
