Abstract: A system (10) for continuously circulating fluid to and through a tubular string either of coiled tubing or made up of a plurality of tubulars connected end-to-end while an upper tubular (32) is added to or removed from a top tubular (26) of the plurality of tubulars, all tubulars having a top-to-bottom fluid flow channel therethrough. The system has an upper chamber (43) with an upper sealing apparatus (34) for sealingly encompassing a portion of the upper tubular, a lower chamber (45) with a lower sealing apparatus (36) for sealingly encompassing a portion of the top tubular (26), one of the upper chamber and the lower chamber sized for accommodating connection and disconnection therein of the upper tubular and the top tubular, and gate apparatus (60) between and in fluid communication with the upper chamber and the lower chamber.
Abstract translation: 一种系统（10），用于将流体连续地循环到通过连续油管的管状管线或者由多个管状端头连接的管状管道连续循环，同时上部管道（32）被添加到顶部管（或 26），所有的管都具有穿过其的顶部到底部的流体流动通道。 该系统具有一上部密封装置（34）的上部腔室（43），用于密封地覆盖上部管状体的一部分，下部腔室（45）具有下部密封装置（36），用于密封地包围顶部管状部分 （26），上室和下室中的一个的尺寸适于容纳上管和顶管的连接和断开，以及门装置（60）在上室和下室之间流体连通。

Abstract: A tong as may be used for a continuous circulation system in a wellbore. The tong has a housing with a hollow interior. A plurality of spaced apart jaw assemblies reside within the housing's hollow interior for engaging a portion of a tubular to be gripped and rotated by the tong. A gear wheel is secured to the housing for rotating the housing and the jaw assemblies. The gear wheel includes a toothed outer circumference for mating with teeth of a drive shaft of a driving motor. A gear flange is movably mounted on the gear wheel such that rotation of the gear wheel does not rotate the gear flange.
