深水区勘探钻完井作业面临着海水深温度低、安全钻井液密度窗口窄、井控风险高、海底地质灾害、台风等诸多挑战。中海油作为深水区勘探作业者，首次组织深水区勘探作业，成功发现了陵水17-2 大型深水气田，推动了深水区油气勘探开发 事业的进一步发展，为实现中海油“二次跨越”迈出了重要的一步。为此简要地回顾了南海西部深水区自营勘探及钻完井项目管 理经验和作业实践，并对我国南海深水区油气勘探开发技术发展愿景提出展望，以期为深水区油气开发事业的发展提供借鉴。

Deepwater exploration drilling and completion operations faces such challenges as low temperature in deep seawater, narrow density vessel for safe drilling fluid, high well control risks, seabed geological disasters, and typhoons. As a deepwater area exploration operator, CNOOC successfully found Lingshui 17-2 large deepwater gas field in its first deepwater exploration operation, and the discovery pushed the further development of oil and gas exploration and development in deepwater area and marked an important step for the “second leap” of CNOOC. The author briefly reviews the management experience and work practices in proprietary exploration, drilling and completion projects in the west deepwater area of the South China Sea and envisions the development prospects of the oil and gas exploration and development technology in deepwater of the South China Sea, in hope of providing some reference for the development of oil and gas exploitation in deepwater area.
