摘要: 提出了一套利用电性变化梯度自动识别夹层的方法,该方法利用夹层的电性特征与上下储集层有一定差异的特点,从而划分出夹层。然后计算夹层的自然伽马变化梯度、微梯度变化梯度、微电位变化梯度、微电极幅度差、声波时差变化梯度、井径变化梯度等参数,将这些参数归一化后绘制雷达图,发现泥质夹层具有高微梯度变化梯度、高微电位变化梯度、高井径变化梯度的特征;灰质夹层具有高声波时差变化梯度及低微电极幅度差的特征;物性夹层具有高微电极幅度差及低声波时差变化梯度的特征。在孤岛油田利用水平井挖潜夹层上部剩余油的过程中,利用这一方法取得了良好的生产效果。

Abstract: It is difficult to properly determine the percolation and variation of low permeability and heterogeneous reservoir that has been developed by water flood process for many years and especially conducting several stimulations. Applying the well test technique can effectively identify such percolation and variation, and provide basis for the reservoir management and reformation. The case study from Shanan reservoir in eastern Junggar basin shows that the feature of such a reservoir has been changed a lot by many-year waterflooding and stimulations, effective analysis of these variations can help to correctly recognize and evaluate this reservoir, thus guide the stable and high production of it.
