底水油藏水平井合理位置的确定方法研究

底水油藏中水平井的合理位置是确保水平井高产稳产、延长无水采油期的关键所在。利用镜像反映及势函数的叠加原理，在获得底水油藏中任意一点的势函数后，得到了底水油藏中水平井底势差和水平井的产量方程，由此研究影响水平井产量、临界产量及见水时间的因素，通过研究获得了底水油藏中水平井的合理位置，为水平井开采底水油藏的优化设计提供了理论基础。

Method of Determining Optimum Well Location for Horizontal Well in Bottom-Water Reservoir

Determining optimum well location for Horizontal well in bottom-water reservoir is the key to keep high and steady production and prolong producing time without water. Using mirror effect and superposition principle of potential function, this paper derives the potential function at arbitrary point in reservoir and acquires the potential difference in horizontal wellbore and production equation of the well. Then, the factors affecting production, critical production and water breakthrough time is studied and the optimum well location for horizontal well in bottom-water reservoir is acquired. It provides the theory base for reasonably developing bottom-water reservoir with horizontal well.
