摘要
为了克服塔里木盆地的地层特点、运输费用昂贵和泥浆用水矿化度高等矛盾，引人欢聚按盐，以代替原泥浆中使用的水解聚丙烯腊接盐作降失水剂。经对基本条件相似的先后完成的20并进行综合对比分析，结果表明，在该区使用双聚铁盐代管由水解聚丙烯阶接盐组成的聚合物或聚磺咸水泥浆，钻井技术上可行，井下安全，经济效益明显。
In order to overcome the problems of formation characteristics, high transportion costs and high saltiness of water used in drilling fluid,the bipoly ammonium salt is recommrnded as a fluid loss additive which takes the place of the hydrolytice polyarylamide salt used in the primary dril1ing fluid. Through comprehensive contrast analyses of two wells drilled with similar basic conditions,the results show that the substitution of bipolyamine sa1t for the polymer consisting of hydrolytic Polyacryamine salt or Poly sulfo-saline water hase drilling fluid used in the area said for drilling is technically viable,the drilling operation is codrcted under the safe downhole condition and the significant economic effect is obtained
