摘要：

针对油藏中分支水平井的稳态渗流问题，基于渗流力学理论，采用全三维方法，导出了油藏稳态渗流与分支水平井井筒流动的耦合模型。用改进的Su方法以及一种新方法计算了裸眼完井分支水平井井筒内的压降，分析和比较了井筒内压力和采油指数的分布情况；同时，给出了考虑经济因素的分支水平井水平段最优长度的计算方法。结果表明，分支水平井的单个分支内的流动情况和水平井近似；由于摩擦因素的影响，分支水平井的水平分支不是越长越好，而是有一个最优值。这些结论可用于实际油藏中分支水平井的设计和产能预测。

Abstract:

In terms of the time-invariant seepage of multi-lateral horizontal wells in oil reservoirs, a coupled model of the time-invariant seepage in reservoirs and the wellbore flow in multi-lateral horizontal wells was deduced with the full 3D analytical method based on the filtration mechanic theory. The pressure drop in barefoot completion multi-lateral horizontal wellbores was calculated using the improved Su method and a new approach, and distributions of pressure and productive indices in wellbores were analyzed and compared. At the same time, a computing method with the consideration of economic factors was proposed to optimize the length of the horizontal section for multi-lateral horizontal wells. The results derived from calculations and analyses of some real cases indicated that the flowing status within an individual branch of multi-lateral horizontal wells was similar to that in horizontal wells, the length of lateral branches of multi-lateral horizontal wells is not the longer, the better, but instead, it has an optimal value due to the friction effect. These conclusions are available for designing multi-lateral horizontal wells and forecasting the productivity of this kind of wells.

Key words: multi-lateral horizontal well, time-invariant seepage, pressure drop, wellbore flow, coupling
