摘要: 根据水平井筒内及油藏内流体流动的数学模型,将水平井的油藏渗流和水平井段中的流动进行耦合,即将原油流入水平井段的点作为节点,来研究水平井段的最优长度,推导出水平井段最优长度的求解方程,并用实例论证了方法的合理和可靠性,为确定水平井水平段合理长度提供了科学的依据。

Abstract: According to the mathematical models of fluid flow in reservoir and in horizontal wellbore, the percolation in reservoir coupled with the flow in horizontal wellbore in this paper, i.e. regarding the location where crude oil runs into wellbore as node, and the optimum well length was studied. The solution to optimum well length was derived and a presented example
demonstrated the reasonableness and feasibility of this approach. The study of this paper developed a methodology to calculate the optimum horizontal well length.

Key words: horizontal well, percolation model, coupling, optimum lengt
