中文摘要:高温、高压、深井、小井眼尾管固井是固井技术的一个难点，龙16井在各项配套工程技术措施综合应用的情况下施工成功，为高温、高压、深井固井作业积累了经验。龙16井是川北低平褶皱带九龙山构造上的一口预探井，[JP2]原设计2159 mm井眼钻至下二叠系完钻。由于地质条件复杂，纵向上分布多套产层并具有超高压特点，地层裂缝发育，多次出现涌漏同存复杂情况，被迫提前下入1778 mm套管固井以封隔上部复杂井段。采用1492 mm钻头钻至598800 m完钻并进行了尾管固井作业。固井作业前钻井液密度234

Application of Liner Cementing Technology in HTHP Slim-hole
Abstract:The liner cementing under high temperature and high pressure in slim-hole is difficult. Well Long-16 is an important preliminary prospecting well in Chuanbei low and flat fold belt of Jiulongshan structure. The original 2159mm hole was designed to complete in Permian, but as well kick and circulation loss happened frequently, 1778mm casing was put down to cement the upper well section ahead of schedule. In this case, 1492mm bit was used to 598800m, and liner cementing was completed. Before cementing, oil gas showed strongly with drilling fluid density of 234g/cm3 and well temperature of 1396℃.
