摘要:
砾岩油藏由于近物源、多水系和快速多变的沉积环境导致储层岩性复杂以及测井响应无规律性变化等特点,岩性的准确识别成为该类油藏调整开发的重点和难点。以克拉玛依油田六中区克下组砾岩油藏为研究对象,利用决策树的分析方法,结合密闭取心资料对砾岩油藏8种岩性的测井曲线敏感性进行研究,优选出原状地层电阻率、声波时差和自然伽马3个测井响应值作为砾岩油藏岩性识别的特征参数,建立决策树岩性识别模型,模型的综合判断准确率达到96.97%,在油田的二次调整开发和水淹层的评价中取得了很好的应用效果。在决策树方法分析结果的基础上,利用地球物理方法制作了砾岩油藏岩性识别图版,数据挖掘方法与地球物理方法的有效结合对解决油田勘探和开发中的复杂问题提供了一种新思路和新方法。
