A Method to Determine the Layered Injection Allocation Rates for Water Injection Wells in High Water Cut Oilfield Based on Displacement Quantitative Characterization

  • 摘要: 多层合采油藏进入高含水期之后,由于层间驱替程度差异加大,导致常用分层配注方法的效果变差。为此,在分析多层合采油藏长期注水开发特点的基础上,提出采用驱替通量定量表征各层驱替程度差异的方法,并以均衡驱替为目标,综合考虑储层厚度、孔隙度、注水历史、调控周期等因素的影响,建立了基于驱替通量均衡化思想的注水井纵向各层配注量确定方法。运用精细油藏数值模拟方法分析了厚度法、地层系数法、剩余油法和基于驱替定量表征的均衡驱替方法在不同含水阶段的适应性。数值模拟结果显示,含水率小于50%时,推荐采用厚度法;含水率为50%~80%时,推荐采用剩余油法;含水率为80%~90%时,推荐采用均衡驱替法。渤海SZ油田X1井组在高含水期采用均衡法调整配注量,调整后井组平均含水率下降4%,日增油117 m3,降水增油效果显著。研究结果表明,基于驱替定量表征的分层配注量确定方法可用于指导高含水期多层合采油藏注水井各层配注量的调整。
