| 摘 要： | 基于瞬时源函数法和势的叠加原理,采用空间和时间的离散技术,建立简化的大斜度井油藏渗流模型,并通过与传统模型对比验证新建模型的准确性。根据油藏-井筒耦合关系,建立大斜度井流入动态模型,并给出求解方法。分析结果表明:无限大顶底封闭油藏大斜度井在定产量生产过程中,井斜角和储层厚度对流入动态的影响在早期径向流阶段最小,在中期过渡流阶段逐渐增大,到晚期拟径向流阶段达到稳定;储层越厚,井斜角越大,井底势降越小;储层越薄,井斜角越大,端部效应越强;井筒两端较大的边界影响是导致大斜度井与水平井流入动态差异的主要原因。

| Abstract: | Based on instantaneous point functions technique and superposition principle,a simplified reservoir inflow model was developed for highly deviated wells by time and space discretization.The validity of the model was tested and verified by comparing with other traditional models.On this basis,an inflow performance model of highly deviated wells was developed according to the coupling between reservoir flow and wellbore flow.The solution method was also presented.Using this model,the inflow performance of a h... |
