一、前言在石油钻井和地质钻探(冶金,煤田,水文工程,水电等)中,钻进复杂地层时,经常使用泥浆,以保证快速,安全钻进和低成本。为了使泥浆保持必要的性能指标,对泥浆应进行化学处理。除了使用无机处理剂对泥浆进行化学处理外,还使用有机高分子处理剂。目前使用的有机高分子处理剂有两 I. INTRODUCTION In oil drilling and geological drilling (metallurgy, coalfields, hydrological engineering, hydropower, etc.), mud is often used to drill complex formations to ensure rapid, safe drilling and low cost. The mud should be chemically treated in order to maintain the necessary performance of the mud. In addition to the use of inorganic treatment agent for chemical treatment of mud, but also the use of organic polymer treatment agent. The current use of organic polymer treatment agent has two
