摘要： A grinding arrangement is described to remove sharp edges on a pipe coupling (51) of a drill string (50), as a consequence of marks from the jaws of pliers and machines used to connect the pipe couplings (51) on a drill deck. A receiving unit (30) is arranged to receive a grinding unit (36) which is equipped with at least one grinding element (38), as the grinding unit (36) is arranged to be driven into the receiving unit (30) with the help of the drill string (50) or a suitable running tool and to be locked securely into the receiving unit (30). Furthermore, the receiving unit is arranged in a riser, landing string or in other connections between the drill deck and a wellhead and over a sealing arrangement for dynamic sealing around the drill string (50) during pressure controlled drilling.
摘要翻译：描述了一种研磨装置，用于从用于将管接头（51）连接在钻台上的钳子和机器的钳口的标记的结果，去除钻柱（50）的管接头（51）上的锋利边缘。接收单元（30）被布置成接收装备有至少一个研磨元件（38）的研磨单元（36），当研磨单元（36）布置成被驱动到接收单元（30）中时钻杆（50）或合适的运行工具的帮助并被牢固地锁定到接收单元（30）中。此外，接收单元布置在提升管，着陆线或钻井平台与井口之间的其他连接中，并且在压力控制钻井期间围绕钻柱（50）周围的密封装置进行动态密封。

摘要： A device is described for maintaining a predominately constant pressure on, and flow of drilling fluid in, a drill string (100) where drilling fluid is supplied via a circulation system for drilling fluid. The device comprises a mainly elongated, internally hollow body (10) arranged to surround the drill string where the hollow body (10) comprises at least an upper pressure chamber (40a) and a lower pressure chamber (40b) connected with respective inlet and/or outlet (50a, 50b) for drilling fluid from or to the drilling fluid circulation system, as said pressure chambers (40a, 40b) are able to be closed and separated by an intermediate valve (70) arranged for circulation of drilling fluid into or out of the drill string (100) during coupling up or disconnecting of a new length of drill string (100). A method to maintain the mainly constant pressure of drilling fluid in a drill string is also described.
摘要翻译：描述了一种装置，用于在钻柱（100）中保持主要恒定的压力和钻井液的流动，其中通过用于钻井流体的循环系统供应钻井液。该装置包括主要是细长的内部中空的本体（10），其布置成围绕钻柱，其中中空体（10）包括至少一个上压力室（40a）和与各个入口和/ 或用于从钻井流体循环系统钻出流体的出口（50a，50b），因为所述压力室（40a，40b）能够被布置成用于将钻井流体循环进入或在连接或断开新长度的钻柱（100）期间，从钻柱（100）出来。还描述了在钻柱中保持钻井液的主要恒定压力的方法。
