摘要:
水平井由于采油速度快,井控面积大而得到广泛应用,但在开采后期易发生水淹且难以治理,所以对其水窜规律的研究尤为重要。前人对底水油藏水平井的水淹规律进行了详细研究,但有关边水油藏的研究很少。采用数值模拟方法,通过水油比和水油比增量与生产时间的双对数曲线特征来识别水平井水窜类型,总结出点状局部见水、线性见水和多点见水水淹规律。实践证明,该识别方法对于油田水平井控水具有一定的指导意义。
Abstract:
Horizontal wells are widely used due to their higher oil production rate and larger well control area,but it is easy to be flooded and difficult to control in the later stage of production.So,it is especially important to study the law of water channeling.The predecessors have conducted detailed studies on waterflooding law of horizontal wells in the bottom water reservoir,but there are few studies on edge water reservoirs.By the means of numerical simulation,the type of horizontal well flow is identified through the characteristics of double logarithmic curves of water-oil ratio and water-oil ratio increment with production time.On this basis,it is summarized the rules of spot-like local,linear,and multi-point water breakthroughs.Through practice,it is proved that the identification method has a certain guiding significance for the water control of horizontal wells in oilfields.
