摘要
Aimed to the complex strata of Pulang copper mining area of Shangri-La,and by the experimental date and theoretical 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 for ZK0409,the drilling difficulties in complex strata of Pulang copper mining area of Shangri-La were vercome.The paper discussed the optimum formula of the solid-free polymer drilling fluid and analyzed its action mechanism in complex strata.
