摘要

摘要: 针对常规防磨接头存在防磨套刚性强易磨损套管、镶嵌防磨套易脱落造成井下故障及安放位置难以确定的缺点，提出采用非金属防磨接头配合钻井液用耐磨减磨剂的双效防磨技术，非金属防磨接头耐磨且对套管磨损小，耐磨减磨剂入井后能够迅速吸附在钻具和套管表面形成高强度低摩阻有机耐磨层。利用计算出的套管内钻柱侧向载荷及现场测出的接头流阻增加值，确定入井防磨接头的数量和位置，根据耐磨减磨剂与钻井液相容性试验结果确定其加量。在X202井的现场试验表明，非金属防磨接头入井连续使用时间超过500 h，平均磨损率仅6.5%，平均返出铁屑量从124.64 g/h降至78.00 g/h，减磨效果显著。研究表明，采取双效防磨措施减缓深井套管磨损具有可行性，为深井、定向井和水平井钻井过程中的套管和钻具防磨提供了新的技术支持。

Abstract: The conventional antiwear connector with strong rigidity is likely to cause wear to casing,inlaid wear jacket may fall off,causing downhole accident,and the position of inlaid wear jacket is difficult to detect.In view of these shortcomings,a solution of non-metallic antiwear connector combined with friction modifiers of drilling fluid was proposed,which was named as the double-effect antiwear technique,the non-metallic antiwear connector had good antiwear performance,and little wear to casing,friction modifiers would quickly be absorbed on the surface of drill pipe and casing to create a high-strength, low-friction organic antiwear layer once it entered the well.Using calculated lateral load of the drill string in the casing,and the increased flow resistance value measured on site,the number and location of antiwear connectors could be determined,and the dosage of friction modifier was calculated according to compatibility test of the friction modifier and drilling fluid.Field test in Well X202 indicated that the non-metallic antiwear connector used continuously for more than 500 h had an average wear rate of merely 6.5%,and the average amount of iron flowback from wellbore reduced from 124.64 g/h to 78.00 g/h,which showed significant wear reduction.The study showed it was feasible to reduce casing wear with this technique,opening a new way for reducing the wear of casing and drill string during the drilling of deep,directional and horizontal wells.
