泥浆作为钻进冲洗液,仍然是钻孔护壁堵漏的一种有效的基本手段。我国七十年代发展起来的聚合物新型泥浆体系,不但促进了泥浆科研技术的发展,更重要的是,对于提高复杂地层护壁堵漏的技术经济效果,发挥了良好的作用。以聚丙烯酰胺、聚丙烯腈为主要原料的新的泥浆处理剂的研究与应用,正把聚合物不分散低固相泥浆体系提到更高的阶段。 1982年,我们在二六二大队复杂地层护壁堵漏的综合治理中,采用河南汲县第一化工厂 Mud as a drilling fluid, drilling and retaining wall is still an effective and basic means. The new polymer system developed in the seventies of our country not only promoted the development of mud science and technology research but more importantly, played a good role in improving the technical and economical effect of plugging the walls in complex formations. Polyacrylamide, polyacrylonitrile as the main raw material of the new mud treatment agent research and application of the polymer is not dispersed low solid mud system mentioned in a higher stage. In 1982, in the comprehensive management of the complex wall blocking of the 246th Brigade, we adopted the first chemical plant in Jixian, Henan
