摘要
对于注水开发20多年的老油区,地下情况和剩余油分布已经变得十分复杂。提出分层、分区块进行水淹层评价,以 A油田B区主力油藏M9砂体为例,对油藏水淹机理进行了详细研究,为油藏水淹层评价提供了可靠的理论基础和实践 经验。
Due to more than 20 years of flooding development of the old oil area, the underground circumstance and the distribution of remaining oil saturation have become very complicated. The evaluation methods for waterflooding layers should be based on subdivisions of layers and blocks. Take the sand of major oil reservoir M9 of Block B in oil area A for example, the mechanism of the oil reservoir waterflooding is detailed, which provides reliable theory foundation and practice experience for water-flooding layers logging.
