摘　　要：本文根据四川地层特点，针对聚合物钻井液在高温高压井段及盐类污染下，滤失量大，滤饼质量差等问题，研究了抗温抗盐性聚合物滤失剂ＣＰＦ。室内研究表明：ＣＰＦ在１８０℃的淡水钻井液中，或在１５０℃的含盐钻井液中（ＮａＣｌ３×１０５ｍｇ／Ｌ，Ｃａ２＋３×１０３ｍｇ／Ｌ），均能有效的降低滤失量，且热稳定性好。在四川、吐哈等油气田应用，取得了良好的效果。Based on stratigraphic features in Sichuan,taking into consideration of the high filtration and poor filter cake quality etc.of polymer drilling fluid when drilling in HPHT sections and encountering salt pollution, the heat-resistant and salt-tolerant polymer filtration reducer CPF is developed. Indoor research shows that CPF can effectively reduce filtration and has good thermal stability in freshwater drilling fluid at 180℃ or in brine drilling fluid (NaCl 3×10 5mg/l,Ca 2+ 3×10 3mg/l) at 150℃.Its applications in Sichuan and Tuha Oilfield have got good results.
