【摘要】 随着油田钻井的发展和深井海洋钻井项目的增加 ,对钻井添加剂的要求也不断提高 ,以满足耐盐性和抗高温性的新要求。 2 -丙烯酰胺基 - 2 -甲基丙磺酸 (AMPS)的分子结构中具有强阴离子性、亲水性的磺酸基和不饱和的乙烯基双键 ,以其为基料的多元聚合物具有良好的热稳定性和抗盐能力 ,是一种新型的耐温抗盐钻井添加剂 ,在降滤失剂、缓凝剂等方面有着广泛的应用 ,是今后油田钻井添加剂的一个重要发展方向。更多还原

【Abstract】 With the development of oil drilling and the increase of the deep or ocean drilling,the requirements of drilling additives were also promoted to satisfy the heat resistances and salt tolerances. 2-Acrylamido-2-methylpropane sulfonic acid (AMPS) is an acrylamide derivatives with -SO 3H and -CH 2=CH 2- in its molecular structures. The copolymers of AMPS with other monomers were a new kind of drilling additives with many specific characteristics and have been widely used in the oil fields. the recent research and application of AMPS copolymers and foreseen the future development direction of AMPS copolymers were introduced in this paper.更多还原
