提高冲洗液质量,是安全钻进地质勘探深孔的保证.为改善冲洗液性质,目前已提出以聚丙烯酰胺为基础制备的一种冲洗液.工业用8%聚丙烯酰胺水溶液一般为粘稠冻胶状,溶于水则成胶质液体.以聚丙烯酰胺为基础制备冲洗液,必须使用水解的聚丙烯酰胺.在泥浆搅拌机中灌注1立方米的水,加入15公斤苛性钠和碳酸钠,150公斤8%的聚丙烯酰胺溶液或12公斤100%的干聚丙烯酰胺,仔细搅拌后即形成水解聚丙烯酰胺溶液.往泥浆搅拌机中加入8%的聚丙烯酰胺溶液时,要以15～20公斤为一份,逐次加
Improving the quality of the flushing fluid is a guarantee of safe drilling of deep holes for geological exploration.In order to improve the properties of the flushing fluid, a flushing solution based on polyacrylamide has been proposed.Industrial 8% polyacrylamide aqueous solution is generally viscous Gel-like, soluble in water is a plastic liquid.Preparation of rinse based on polyacrylamide, you must use hydrolyzed polyacrylamide in the mud mixer perfusion 1 cubic meter of water, add 15 kg of caustic soda and sodium carbonate , 150 kg of 8% polyacrylamide solution or 12 kg of 100% dry polyacrylamide, stirring to form a hydrolyzed polyacrylamide solution to the slurry mixer 8% polyacrylamide solution, to 15 ~ 20 kg for one, followed by Canada
