油田开发到了后期,综合含水不断升高,目前,华北油田平均含水量为80％～90％。由于一次沉降后不能确定油水界面,放底水效果不好,造成脱前含水高达40％,这不仅造成加热炉负荷增高,浪费燃料油,同时也使脱水器超负荷运行、电压低、电流大、脱水质量不合格。为此,中国石油天然气华北石油管 At the late stage of oilfield development, the integrated water content has been increasing. At present, the average water content in Huabei Oilfield is 80% -90%. As a settlement can not be determined after the oil-water interface, put bottom water effect is not good, resulting in pre-off water up to 40%, which not only caused the furnace load increased waste of fuel oil, but also make the dehydrator overload operation, low voltage, large current , Dehydration quality unqualified. To this end, China North Oil and Natural Gas Pipeline
