在石油井生产初期原油一般不含水,但是随着油井的开采,原油很快就会含水,并且含水量将逐渐增高。当原油的含水量在60%以下时,一般情况下都形成比较稳定的油包水乳状液。出现游离水时的含水量,视原油中所含的天然表面活性剂的性质,数量以及油气集输工艺流程的类型而定。不论游离水和乳状液的比例如何,含水原油都需经脱水工序,才能成为商品原油。因此需要在油水混合液中添加破乳剂,利用热化学或电化 Crude oil generally does not contain water in the early stages of production of the oil well, but as the well is drilled, the crude oil will soon contain water and the water content will gradually increase. When the crude oil moisture content below 60%, under normal circumstances are formed more stable water-in-oil emulsion. The water content of free water depends on the nature and amount of natural surfactants contained in the crude oil and on the type of hydrocarbon accumulation process. Regardless of the ratio of free water to the emulsion, water-containing crude oil needs to be dehydrated to become a commodity crude. Therefore need to add oil and water mixture demulsifier, the use of thermochemical or electrochemical
