秘鲁1AB老油田强天然水驱油藏剩余油分布规律研究

Study on rule of residual oil distribution of strong natural water-injection reservoir in 1AB depleted field of Peru.

文中针对秘鲁1AB老油田开发面临的低幅度构造识别、强天然水驱特高含水开发等难题,系统研究并总结了该油田的低幅度构造圈闭成因与识别技术、水淹油层的测井曲线特征与识别方法、隔夹层类型和识别技术以及对油田水驱开发的影响等。在此基础上,分析了不同类型油藏特征和剩余油分布规律,为老油田挖潜指明了方向并确定了目标。

In view of difficulties of identifying low-amplitude structure and higher water-bearing development of strong natural water injection faced in 1AB depleted field of Peru,the paper systematically studied and summarized the genesis of low-amplitude structural trap and recognition technique,the logging characters and recognition method of water-flooded oilfield,parting types and recognition technique and influence on development of water-injection oilfield.On that basis,the paper analyzed the feature of differ...
