近日，亚洲第一深水导管架平台“海基二号”平台首口开发井正式开钻，我国首个深水油田二次开发项目“新优快”钻井作业拉开序幕。
我国首个深水油田升级焕新
“海基二号”平台服役于我国首个深水油田流花11-1油田，作业水深324米。平台集钻井、生产、生活等多功能于一体，总高度达428米，总重量超5万吨，是亚洲最高最重的海上原油生产平台。
流花11-1油田采用“深水固定式平台+圆筒型FPSO（浮式生产储卸油装置）”模式开发，部署开发井24口，钻井总进尺超73500米，相当于钻穿8座珠穆朗玛峰。
为充分提高深水边际油气田的开发效果，平台将规模化实施长水平段大位移井9口，最大井深5216米，水平位移4473米，水垂比达3.62。
这是我国首次在超300米水深海域通过固定式平台开采油气，此模式与采用移动式钻井平台相比可降低钻完井成本超50%，进一步完善了我国深水钻完井技术体系，促进深水油气田经济高效开发。
