摘要:吐哈油田底水油藏已进入中高含水开发期,前期抑雏技术虽然取得了一定效果,但由于技术自身原因无法推
用,为此提出了电泵十喷射泵油水分采技术思路,利用电泵对水层进行强采消锥,并为喷射泵提供高压动力液,吸入油层流体并
举升至地面。通过2年的技术攻关和现场试验,该技术已经成熟,满足了提高底水油藏技术可采儁量和油水比灵活控制以及生
产测试的要求,取得了良好的应用效果。

Abstract: Now the recovery percent of geological reserves is low, while that of the technically recoverable reserves is high in bot-
tom 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-inhibitin echnolo y However the echnology 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 lo, 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
