摘　　要：对油气井产出物进行海底处理是研制开发水下生产系统的核心问题,而海底多相流的增压泵送和分离则是海底处理技术中的基石。螺旋-轴流式和双螺杆式多相泵是2种最主要的海底多相流泵,目前至少有3家公司的产品达到了商业化运行阶段。与海底处理技术密切相关的气-液分离技术主要包括G—SepTM紧凑型旋流脱气器、垂直环空分离和泵送系统、超音速气-液分离器等,液-液分离技术则在常规重力沉降分离的基础上出现了静电聚结强化型重力沉降分离和管式分离器。我国应尽快围绕海底油-水分离技术所涉及的一些实质性问题开展相关研究。The subsea treatment of produced substances in oil and gas well is a core issue of developing underwater production system, and the pressurized pumping and separation of subsea multi-phase flow is the base of subsea treatment technology. The helical-axial flow type and dual screw type multi-phase pumps are two main subsea multi-phase flow pumps. Currently there are at least three manufacturers whose products have reached the commercial operation period. The gas-liquid separation technology closely related to the treatment technology includes G-SepTM compact cyclone degasser, vertical annulus separation and pumping system as well as ultrasonic gas-liquid separator. But the liquid-liquid separation technology has static gathering intensity type gravity precipitation separation and pipe-type separator based on the common gravity precipitation separation. The relevant study about the substantial issues concerning subsea oil-water separation technology should be carried out as soon as possible in our country.
