低临界溶解温度(LCST)型温度敏感聚合物是指聚合物链在相转变温度前呈伸展溶解态、相转变温度后为收缩聚集态的温度敏感型聚合物,其在环境温度变化刺激下能智能且可逆响应,已在有机化工、材料科学、生物医学和石油天然气工业等领域得到了广泛研究.该文对不同空间构象的LCST型温度敏感聚合物进行了分类,重点介绍了线形结构、温敏水凝胶、嵌段结构、接枝复合结构和特殊结构的LCST型温度敏感聚合物的研究进展;总结了不同空间构象的LCST型温度敏感聚合物在低温流变调控、温敏智能封堵、增黏提切和防漏堵漏钻井液领域的应用现状,提出了 LCST型温度敏感聚合物存在的关键问题及其在钻井液领域的应用前景.
Research on LCST-type temperature-sensitive polymers and their application progress in drilling fluids
Low critical solvation temperature(LCST)temperature-sensitive polymers are temperature-sensitive polymers whose chains present a stretch solution state before the phase transition temperature and a shrink aggregation state after the phase transition temperature.With intelligent and reversible response to ambient temperature change,LCST have been widely studied in the fields of organic chemistry,materials science,biomedicine,and oil and gas industry.In this review,LCST-type temperature-sensitive polymers with different spatial conformations were categorized,with a focus on the research progress on LCST-type temperature-sensitive polymers with linear structures,temperature-sensitive hydrogels,block structures,grafted composite structures and special structures.The application status quo of LCST-type temperature-sensitive polymers with different spatial conformations in drilling fluids,such as low-temperature rheology control,temperature-sensitive intelligent plugging,viscosity enhancement and cutting,and leakage prevention and plugging,were summarized.Finally,the key problems of LCST-type temperature-sensitive polymers and their application prospects in the field of drilling fluids were discussed.
