中国海洋油气正处于增储上产的关键时期,但南海东部海域存在老旧移动式钻井平台设备抗环境能力较差、设施服役年限较长、设备能力不足、设备安全性差等问题,严重制约了中国海洋油气向深远海进军的步伐,亟需解决移动式钻机的更新换代问题。分析了智能中深水钻探装备深蓝探索号的抗环境能力和主、辅井口作业模式,总结了深蓝探索号在国内多口井的高效作业情况,并与老旧移动式钻机作业时效进行了对比。对比结果表明:深蓝探索号最高能够抵抗16级台风,南海东部海域台风季节和冬季季风恶劣环境下的作业能力较强;主、辅井口作业模式可以实现主、辅井口同时作业,相比常规单井口模式,综合作业时效提高15%左右。研究结果对南海东部油田引入中深水钻机设备选型提供了参考,有助于推动安全高效、抗环境能力强的高端装备制造和应用。

 China’s offshore oil and gas industry is currently in a critical period of increasing reserves and production. However, issues such as the poor environmental resistance, long service life, insufficient equipment capacity, and poor safety of old mobile drilling platform in the eastern South China Sea seriously restrict China’s advancement into deep and distant sea areas. It is urgent to address the problem of updating and replacing mobile drilling rig. Therefore, this paper analyzes the environmental resistance and main/auxiliary dual wellhead operation mode of intelligent medium-to-deep water drilling rig“Deep Blue Explorer”, summarizes its efficient operation in multiple domestic wells, and compares it with the operational efficiency of old mobile drilling rigs. The comparison results show that the SLTS drilling rig can withstand up typhoons up to category 16 and has strong operational capacity to resist the harsh environment during typhoon seasons and winter monsoons in the eastern South China Sea. The main/auxiliary dual wellhead operation mode can achieve simultaneous operation at both wellheads, improving overall operational efficiency by about 15% compared to conventional single wellhead modes. The research results provide reference for the selection of drilling rigs when introducing medium-to-deep water drilling platforms in the eastern oil fields of the South China Sea, helping to promote the manufacturing and application of safe, efficient, and environmentally resistant highend equipment.
