摘　　要：海上油田热采对水质要求严格,海水不能直接作为热采用水;海水资源丰富,取材方便,但常规水处理设备无法处理,陆地用海水淡化装置又由于体积大无法安装在海洋平台上。文章介绍了中海油田服务股份有限公司专门研制的海水淡化处理装置的主要设备、工艺流程、运行参数及处理效果,并对其经济效益进行了对比分析。该装置结构紧凑,占地面积小,适合在海洋平台上安装使用;产水量达到20 m3/h;处理后的产出水总硬度为0.2 mg/L,总碱度为20.80 mg/L,悬浮物含量小于1 mg/L,产出水水质满足多元热流体热采对水质的要求。Sea water resource is almost unlimited and easily obtained,but the water quality requirements of offshore oilfield thermal recovery are rigorous. Seawater is not able to satisfy the quality requirement,even after being treated by conventional water treatment equipment,and onshore seawater desalination unit can not be installed on offshore platform due to its big volume. The seawater desalination unit developed by COSL has compact design,small footprint area and water production of up to 20 m3/h. The totalhardness of treated wateris 0.2 mg/L,totalalkalinityis20.80 mg/L,and content of soliquoid is less than 1 mg/L. The water quality meets the demand of multiple fluid thermalrecovery.
