| Abstract_FL | A new quaternary polymer retarder C-R45L has been developed through molecular design to overcome the shortcomings of the conventional chain polymer retarders such as poor regularity,easy to cause overtime retardation at medium-low temperatures and slow development of strength etc.The raw materials for the synthesis of C-R45L include 2-acrylamido-2-methylpropanesulfonic acid(AMPS),itaconic acid(IA),sodium styrene sulfonate(SSS)and a long-chain hydrophobic associative monomer TAS-24.Study on C-R45L with IR spectroscopy and laboratory evaluation of C-R45L's effects on the performance of cement slurries show that C-R45L has good retarding effect;a cement slurry treated with 4%C-R45L has thickening time of 347 min at 210℃.At high and medium-low temperatures,C-R45L has good retarding regularity.C-R45L can be used at high-temperature,medium-temperature and low-temperature operations.It has no adverse effect on the compressive strength of set cement,the medium/low temperature strengths and the top strength of set cement develop very fast.Good wide-temperature-range performance makes C-R45L suitable for use in cementing long open holes.C-R45L has been successfully used in cementing the exploration well Gutan-1,and excellent cementing job quality was obtained. |
