【摘要】：目前全球陸地和淺海經過長期勘探開發(fā),重大油氣發(fā)現越來越少,規(guī)模越來越小。隨著石油勘探技術的進步,人們逐漸將目光轉向深海。而在深海洋油氣資源鉆采以及生產之前,需要對局部海域的海底地形地貌、地質特征等海底進行全面的勘探調查。為此,迫切需要研制一種適合深水作業(yè)的勘察船。鉆井系統(tǒng)技術應用研究是深水工程勘察船及配套技術的重要組成部分,可為實現安全、高效勘察作業(yè)配置切實可行的鉆井設備配套方案。本文對深水工程勘察船鉆井系統(tǒng)進行了總體研究,通過對勘察船鉆井特點和勘察船鉆井系統(tǒng)的設備的特殊要求的分析研究,提出了一個具有先進水平的鉆井系統(tǒng)配置方案,成功開發(fā)了可適應水深3000、鉆深200米、鉤載225噸的勘察船鉆機系統(tǒng)。另外對關鍵設備如海洋動態(tài)井架、大通徑頂驅、鉆柱升沉補償系統(tǒng)、管子處理系統(tǒng)和海底基盤的進行了適應深水勘察船鉆機系統(tǒng)的詳細分析研究�？辈齑某晒ㄔ焯岣吡宋覈钏@井系統(tǒng)的技術能力,為我國深水鉆井系統(tǒng)的進一步發(fā)展打下了堅實的基礎。
[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.
