科学与技术的发展使海上油田钻探和生产技术在过去５０ａ发生了显著进步 ,导致１９４７年在墨西哥湾水深２０英尺处安装了第一个海上平台 ,随后深浅海区在确定、开发和利用新、老油田的方法上取得了巨大进展。随着技术的发展 ,深水定义也随时间发生了变化。２０世纪７０年代深 Advances in science and technology have led to significant advances in offshore oilfield drilling and production technology over the past 50 years, leading to the installation of the first offshore platform at a depth of about 20 feet in the Gulf of Mexico in 1947, followed by the identification and exploitation of new and old Great progress has been made in the field approach. As technology has evolved, the definition of deep water has also changed over time. Deep in the 1970s
