油田开发过程中普遍存在着层间与层内干扰，对于纵向上没完全隔开的海上强非均质性巨厚砂砾岩油藏而言尤为如此，是油藏细分层系的基础和内因。矿场上，干扰数据主要由生产测井得到，开发经验表明干扰系数随开发阶段、时间变化而变化，生产测井普遍为单点测试，无法得到全周期干扰系数。因此，有必要对层间与层内干扰进行室内实验研究。干扰系数理论研究涉及参数众多且随时间变化，可以解释多层合采油井整体产油能力低于分层开采累加量现象，未能解决其形成的理论根源，所以采用了一维岩心驱替实验装置进行了层间和层内干扰的研究，实验表明：巨厚砂砾岩油藏层间干扰随着时间推移，含水上升，干扰系数逐渐增大，但在高含水期有所下降，导致层间干扰的原因是单驱与合驱时各岩心驱替压力梯度不同；巨厚砂砾岩油藏层内干扰在早期采油指数干扰系数较大，随着含水增加，采油指数干扰系数逐渐变小，层内干扰产生的实质是不同储层渗流阻力变化随着时间的变化，导致储层流量分配的改变。

The interlayer and intralayer interference, which is commonly existing in the process of oilfield development, especially for the offshore strongly heterogeneous huge thick sandstone and conglomerate reservoirs that are not completely separated vertically, is the basis and internal cause of reservoir subdivision. In practice, interference data are primarily obtained from production logging, which shows that the interference coefficient changes with the development stage and over time. Since production logging is typically a point test, it does not capture the full cycle interference coefficient, highlighting the need for laboratory studies on interlayer and intralayer interference. The theoretical study of interference coefficient involves numerous parameters and the interference coefficient changes with time. This theory can explain the phenomenon that the overall oil production capacity of multi-layer combined production wells is lower than the cumulative amount of multi-layer production, but it fails to solve the theoretical root cause of its formation. So a one-dimensional core displacement experimental device was used for the study of the interlayer and intralayer interference. The experiment shows that for the interlayer interference, the interference coefficient gradually increases with time as water cut rises, but decreases in high water cut period. This is due to the difference in the displacement pressure gradient of each core during single flooding and combined flooding. While for the intralayer interference, the interference coefficient of oil production index is large in the early stage, and gradually decreases with the increase of water cut. The essence of the interference is that the change of seepage resistance of different reservoirs with time results in the change of reservoir flow distribution.
