文昌13-1/2油田总产液量超过三相分离器原设计处理能力,处理后原油含水率超标,同时打调整井、换大泵提液等增产措施受到限制。为解决这一瓶颈,充分利用油田现有生产设施,对FPSO油气水三相分离器进行了排水改造,使三相分离器生产污水处理能力得到了显著提高,同时原油处理质量得到明显改善,满足了油田提液增产要求。
The total production volume of Wenchang 13-1 / 2 oilfield exceeded the original design capacity of the three-phase separator. After the treatment, the water content of the crude oil exceeded the standard. At the same time, the stimulation measures such as adjusting the well and changing the pump fluid were limited. In order to solve this bottleneck and make full use of the existing production facilities in the oilfield, the FPSO oil-water-water three-phase separator was drained and rebuilt so that the sewage treatment capacity of the three-phase separator was significantly improved and the crude oil treatment quality was significantly improved The oil extraction liquid yield requirements.
