【摘要】：目前全球陆地和浅海经过长期勘探开发,重大油气发现越来越少,规模越来越小。随着石油勘探技术的进步,人们逐渐将目光转向深海。而在深海洋油气资源钻采以及生产之前,需要对局部海域的海底地形地貌、地质特征等海底进行全面的勘探调查。为此,迫切需要研制一种适合深水作业的勘察船。钻井系统技术应用研究是深水工程勘察船及配套技术的重要组成部分,可为实现安全、高效勘察作业配置切实可行的钻井设备配套方案。本文对深水工程勘察船钻井系统进行了总体研究,通过对勘察船钻井特点和勘察船钻井系统的设备的特殊要求的分析研究,提出了一个具有先进水平的钻井系统配置方案,成功开发了可适应水深3000、钻深200米、钩载225吨的勘察船钻机系统。另外对关键设备如海洋动态井架、大通径顶驱、钻柱升沉补偿系统、管子处理系统和海底基盘的进行了适应深水勘察船钻机系统的详细分析研究。勘察船的成功建造提高了我国深水钻井系统的技术能力,为我国深水钻井系统的进一步发展打下了坚实的基础。
[Abstract]:At present, global land and shallow water after long-term exploration and development, major oil and gas discovery is becoming less and smaller. With the development of petroleum exploration technology, people gradually turn their eyes to the deep sea. Before drilling and production of deep offshore oil and gas resources, it is necessary to carry out a comprehensive exploration and investigation on the seabed topography and geomorphology, geological characteristics and other seafloor in the local sea area. Therefore, it is urgent to develop a survey ship suitable for deep water operation. The application of drilling system technology is an important part of deep water engineering survey ship and its supporting technology. In this paper, the drilling system of deep water engineering reconnaissance ship is studied in general. By analyzing the drilling characteristics of reconnaissance ship and the special requirements of drilling system equipment of reconnaissance ship, an advanced drilling system configuration scheme is put forward. The drilling rig system which can adapt to water depth of 3000 meters, drill depth of 200 meters and hook load of 225 tons has been developed successfully. In addition, the key equipment such as marine dynamic Derrick, Datong diameter top drive, drill string heave compensation system, pipe treatment system and submarine base plate are analyzed and studied in detail. The successful construction of the reconnaissance ship has improved the technical capability of the deep-water drilling system in China and laid a solid foundation for the further development of the deep-water drilling system in China.
