加拿大Fort油田SAGD开发采用由生产井站到集中处理站的二级布站模式。集中处理站由原油脱水装置、污水处理装置、注汽锅炉等构成,采出水经深度处理回用注汽锅炉,产汽经干线输至生产井站。生产模式整体集中,具有油、水、汽一条龙生产的特点。采用了先进的地面工艺技术。如高温调频电脱水、机械压缩法采出水处理、螺旋式换热器等。年开采原油700×104t以上,最终采收率超过50%,最高达70%以上。
SAGD, Fort Field, Canada, developed a two-stage distribution system from production wells to centralized processing stations. Centralized processing station consists of crude oil dewatering unit, sewage treatment plant, steam injection boilers and other components. The treated water is returned to the injection steam boiler through advanced treatment and the steam is delivered to the production well station through the trunk line. The overall concentration of production patterns, with oil, water, steam one-stop production characteristics. Using advanced ground technology. Such as high temperature frequency modulation dehydration, mechanical compression mining water treatment, spiral heat exchanger. Annual exploitation of crude oil 700 × 104t above, the ultimate recovery rate of more than 50%, up to 70% or more.
