| 摘 要： | 在井距较小的底水油藏中,井间干扰现象往往影响油井见水时间预测结果的准确性。根据势函数叠加原理,提出考虑井间干扰影响的底水油藏油井见水时间预测方法,探讨井间距离和邻井产量等参数对油井见水时间的影响。计算结果表明,如果井间距离越小、油井产量越大,则井间干扰越大、油井见水时间越早;邻井产量和井距对油井见水时间的影响程度随着井距的增大而减小。

Formula of Water Breakthrough Time of Bottom Water Reservoir Considering Well Interference |
| |
| Abstract: | The interwell interference often affects the accuracy of the prediction results of water breakthrough time in a bottom water reservoir with smaller well spacing. Based on superposition principle of potential function, a new prediction formula considering the phenomenon of well interference is set up to explore the effects of the distance between adjacent wells and oil well production on water breakthrough time. The results show that smaller distance and greater oil well production would cause bigger interference and earlier water breakthrough time. The influence of the output and well spacing of the well on the water breakthrough time of the well decreases with the increase of the well spacing. |
