摘要
试验中，筛选出两性离子型抑制性降粘聚合物XY27做为核心聚合物，并加入弱分散剂、封堵剂、防卡剂、加重剂等成分，配制成钾钙基沥青树脂两性离子聚合物重钻井液，应用于4500～5500m直井和定向井中。应用中表现出了较好的流变性、抑制性、防粘卡效果、高温稳定性和较强的剪切稀释性、滤失造壁性、防塌能力和抗可溶性盐类污染能力。钻井液密度高达1．96g／cm3，机械钻速提高18％。
Through tests,this drilling fluid is compounded of amphoteric ion XY27 as the centerpolymer, dispersant, plugging agent,sticking prevention agent, weighting agent, etc, and used in verticaland directional well of 4500-5500 meters. In the application, it shows the good fluidity, innibity,antisticking effect,stability in high temperature and good shear thinning behavior,filter wall building property, collapse-proof, anti-contamination of salt. The drilling fluid density is high up to 1.96g/cm3,penetration rate is increased by 18%.
