摘要
针对香格里拉普朗铜矿区所遇到的复杂地层,通过室内试验研究,确定采用植物胶作为主剂、聚丙烯酰胺和LP作为辅剂得到无固相聚合物钻井液,在钻探矿区ZK0409钻孔中的绳索取心钻进中使用,成功解决了该矿区复杂地层的钻进问题。探讨了无固相聚合物钻井液的最佳配方,并分析了其在复杂地层钻进中的作用机理。
Aimed to tile complex strata of Pu｜ang copper mining area of Shangri-La, and by the experimental date and Ih~＇o- retieal analysis, the solid-free polymer drilling fluid consisting of host agent （vegetable-gum） and assistant agents（ PAM ＆ LP） was fixed, which was applied in the wire-line drilling construction ibr ZK0409, the drilling difficuhies in complex stra- ta of Pulang copper mining area of Shangri-l,a were vercome. The paper discussed the optimum formula of the solid-free pol- ymer drilling fluid and analyzed its action mechanism in complex strata.
