摘　　要：AD-3井位于新疆塔河油田艾丁地区,属盐下钻井区块,从三开3200m转化为阳离子乳液聚合物钻井液体系,该体系具有较强的抑制性和较高的控制泥页岩地层蠕变的能力。并在此基础上,进一步转化为阳离子聚合物聚磺钻井液体系和阳离子聚合物高密度欠饱和盐水钻井液体系,钻井液体系转化施工顺利,有效控制井下复杂情况的发生,取得了理想的应用效果。Well Aiding-3 is the block of drilling under salts which locates in Xinjiang Tahe oilfield.The drilling fluid is converted into cation emulsion polymer drilling fluid system which has strongly inhibitive ability and can extremely control the creep of mud shale formation.The drilling fluid is converted into polymer-sulfonate and high density under-saturated salt water drilling fluid in base of cation emulsion polymer drilling fluid.The complicated cases and accidents are effectively reduced by the successful conversion of the drilling fluid system.
