Suspended slickwater drag reducer as well as preparation method and application thereof

The invention belongs to the technical field of drag reducers for oil and gas fracturing, particularly relates to a suspension type slickwater drag reducer as well as a preparation method and application thereof, and aims to solve the problems that an existing suspension type slickwater drag reducer is poor in salt tolerance and complex in preparation process. The slickwater drag reducer comprises the following components in percentage by mass: 40%-60% of industrial white oil; 5%-10% of an emulsifier; 8%-12% of a dispersant; 10%-20% of an acrylamide polymer with a sulfonic acid group; and the balance of water. All the components react at normal temperature and normal pressure to obtain the suspension type slick water drag reducer. The suspension type slickwater drag reducer has good salt tolerance and is simple in preparation process. 本发明属于油气压裂所用的减阻剂技术领域，具体涉及了一种悬浮型滑溜水减阻剂及其制备方法和应用，旨在解决现有悬浮型滑溜水减阻剂存在耐盐性差且制作工艺复杂的问题。该滑溜水减阻剂各组分按质量百分比为：工业白油：40％～60％；乳化剂：5％～10％；分散剂：8％～12％；带有磺酸基团的丙烯酰胺类聚合物：10％～20％；其余为水；各组分在常温常压进行反应得到悬浮型
