Composite viscosity reducer sulfonated tannin for modified tannin extract drilling fluid and preparation method of composite viscosity reducer sulfonated tannin
The invention provides a composite viscosity reducer sulfonated tannin for modified tannin extract drilling fluid and a preparation method of the composite viscosity reducer sulfonated tannin, and belongs to the technical field of viscosity reducers for drilling fluid. The composite viscosity reducer sulfonated tannin for the modified tannin extract drilling fluid is formed by grafting, modifying and compounding the modified tannin extract and the acrylic acid-acrylamide multipolymer, the viscosity reduction rate and the high-temperature stability of the drilling fluid can be remarkably improved, meanwhile, the composite viscosity reducer sulfonated tannin also has certain filtration loss reduction and collapse prevention effects, and is good in compatibility and high in stability. The cleaning agent can be matched with various treating agents for use.
本发明提供了一种改性栲胶钻井液用复合降粘剂磺化单宁及其制备方法，属于钻井液用降粘剂技术领域。本发明提供的改性栲胶钻井液用复合降粘剂磺化单宁是由经过改性后的栲胶与丙烯酸‑丙烯酰胺多元共聚物接枝改性复合而成，能够显著提高钻井液的降粘率和高温稳定性，同时还具有一定的降滤失和防塌作用，而且配伍性好，可与多种处理剂配合使用。
