摘要
根据势的迭加原理及镜像反映原理 ,考虑井筒压降 ,应用数学方法 ,建立了油藏斜井三维空间势分布计算模型 ,研究了油藏斜井三维势分布规律 ,并讨论了影响因素。应用该模型得出了不同类型油藏中多个分支井眼在油层势分布公式 ,得出了油层中某点势大小只与井筒产量、长度及该点到井筒两端点的距离有关的结论 ,为进一步研究油井的产能提供了依据。
On the basis of superposition principle and mirror image principle of potential,and considering borehole pressure drop,the computing model of 3-D potential distribution for inclined well reservoir is estabilished by using mathematical method.The law of 3-D potential distribution in inclined well reservoir is studied and the influence factor is also discussed.Through application of the model,the potential distribution formula of multilateral well in different reservoir types is fetched.Through analysis,the value of certain point potential in reservoir is only relative to well production,length and the distance from certain point to the both terminal vertexes of the well bore.It supplies basis for further studying oil productivity.
