聚丙烯酰胺及其衍生物,目前用于钻孔护壁堵漏浆液中的有:非水解聚丙烯酰胺(PAM)、水解聚丙烯酰胺(HPAM)、磺化聚丙烯酰胺(SPAM)和聚丙烯酸钙(CPA)等。它们与其他处理剂配合,配制的低固相泥浆、无固相冲洗液、速效堵漏浆液和水泥浆等,已在生产和实验室试验中取得了一定的结果,对于小口径钻孔的护壁与堵漏已初步显示出其使用效果和应用前景。一、PAM-水玻璃无固相冲洗液由于高效能处理剂的应用,泥浆从高固相进化到低固相,泥浆的性能得到了很大的改善。那么进而能否这样推断,低固相泥浆的进一步发展,将会出现以新的护壁原理和
Polyacrylamide and its derivatives, currently used in drilling wall plugging slurry are: non-hydrolyzed polyacrylamide (PAM), hydrolyzed polyacrylamide (HPAM), sulfonated polyacrylamide (SPAM) and calcium polyacrylate (CPA) and so on. They and other processing agents, the preparation of low-solid mud, solid-free rinse, quick plugging slurry and slurry, etc., have been made in the production and laboratory tests to a certain extent, for the small diameter borehole wall And plugging has shown its initial use and application prospects. First, the PAM-water glass solid-free rinse fluid due to the application of high-performance treatment agent, mud from high to low solid phase solid phase evolution, mud performance has been greatly improved. So then can we deduce that, the further development of low solid mud, there will be a new wall principle and
