A kind of polymer particles encapsulated naphthaleneboronic acid ( NBA ) was prepared via an oil-in-water emulsion polymerization process. 利用水包油乳液聚合法制备包裹了萘硼酸(NBA)的聚合物颗粒。
PH lower will reduce the stability of the emulsion system, emulsion, eventually forming cannot even oil-in-water. PH低会降低乳化体系的稳定性,甚至无法乳化,最终形成水包油。
Therefore, a kind of high-density, weak-gelled, non-bentonite and oil-in-water drilling fluid system is developed. 针对这些难题,研制了一套高密度弱凝胶、无土相水包油钻井液体系。
