油田的石油开采进入不能自喷的阶段后,必须注水驱油,才能增产。陆上油田一般注入淡水。但近年我国北方干旱严重,特别是1997年,黄河河口地区断流十几次,共达221天。造成当地农民连饮水都发生困难。胜利油田已处开采后期,采出液中水含量已占90%以上,注水量大量增加。虽然拥有水面相当于20个杭州西湖大的三个平原水库,但仍不能不一度求救中央特令上游放水来解燃眉之急。
Oil field oil into the spray can not be from the stage, you must flooding flooding in order to increase production. Onshore fields generally inject fresh water. However, in recent years, there is a serious drought in northern China. Especially in 1997, the Yellow River estuarine region cut off a dozen times, reaching a total of 221 days. As a result, local peasants have trouble even drinking water. Shengli Oilfield has been mining late, mining liquid water content has accounted for more than 90%, a substantial increase in water injection. Although it has the equivalent of 20 water reservoirs of three large reservoirs in the West Lake of Hangzhou, it can not solve the immediate needs without first asking for help from the Central Commission.
