Oil-water separate recovery technology with electric pump and jet pump in bottom water reservoir

Now the recovery percent of geological reserves is low, while that of the technically recoverable reserves is high in bottom water reservoir in Turpan-Hami Oilfield which has entered into a period of high water cut. Also some results are obtained by using prophase coning-inhibiting technology. However, the technology could not be applied widely due to its own reasons. In view of this, the oil-water production technology combining electric pump with jet pump is put forward. After two years of technological research and field test, the technology has been improved a lot, meeting the requirement of increasing technically recoverable reserves in bottom water oil reservoir, improving flexible control of oil-water ratio and production test. Good application results have been obtained.
