马王庙油田马50井区改善注水开发效果的对策

Some Strategies for Improving Effectiveness of Waterflooding Development in Ma-50 Well Area of Mawangmiao Oilfield

马王庙油田马50井区注水开发效果较差,目前采出程度只有7.7%,采油速度只有0.56%,综合含水已高达81%,其主要影响因素包括油藏构造复杂、储层具有不同敏感性等。要进一步改善马50井区注水开发效果,应采取开展精细构造解释、及时进行有效注水、进行高压注水和脉冲注水、加强储层伤害机理的研究。

There is poor effectiveness of waterfloocling development in MA--50 well Area of Mawangmiao Oilfield, which has current oil recovery only 7. 7%, oil recovery rate only 0. 56%, while the integrated water cut reaches as high as 81%. The main factors include complicated oil reservoir structure and the reservoir with different sensitivities, etc, Some strategies for improving the effectiveness of waterflooding development in Ma--50 Well Area include explaining fine structure, waterflooding effectively without delay, waterflooding under high pressure, waterfloocling pulsedly and researching reservoir damage mechanism.
