自从顿钻钻机逐步退出历史舞台 ,井身结构随管柱的变化也发生了变化。最近新开发出一种钻井系统 ,它将合成连续油管技术与液力修井技术进行组合运用 ,本文介绍了该复合系统的优越性。新研制的合成连续油管内嵌导线 ,它允许旋转钻井系统与井底钻具组合之间进行连续、实时、双向沟通。这一新技术使钻井系统的控制方面有了非常大的改进。由此也研究开发出一些新的技术 ,如地质导向技术和远程实时控制技术等。作为复合钻井设备的一个组成部分 ,液力修井升降系统拓展了该套钻井设备的作业能力及功能。液力修井机可以用于欠平衡和过平衡两种条件下的联接管柱钻井及完井 ,当它与合成连续油管配合应用时 ,由于有了复合钻井设备 ,油气藏的开发就有了更多的可选性。
Since the Dayton drilling rig gradually withdraw from the stage of history, well structure changes with the string has also changed. Recently a new drilling system has been developed that combines the use of coiled tubing with hydraulic workover technology. This paper presents the benefits of this composite system. The newly developed synthetic coiled tubing embedded wire allows continuous, real-time, two-way communication between the rotary drilling system and the bottom hole assembly. This new technology has greatly improved the control of drilling systems. It also studies and develops some new technologies, such as geosteering technology and remote real-time control technology. As part of a composite drilling rig, the hydraulic workover lift system expands the working capabilities and capabilities of the drilling rig. Hydraulic workover rigs can be used for drilling and completing well-coupled tubing strings under underbalanced and overbalanced conditions. When combined with synthetic coiled tubing, the development of reservoirs is due to the combined drilling equipment More optional.
