摘要
水驱特征曲线法是用来预测水驱油田的产量及可采储量的重要方法,目前国内外学者对水驱特征曲线的研究,已有几十种水驱特征曲线的表达式,由于油田开发的复杂性,各类曲线很难定量描述油田开发的全过程,而只适用于某一特定阶段。基于前人提出的几种水驱特征曲线,提出了第2种水驱曲线结合第10种水驱曲线的新型水驱特征曲线以及丙型与第10种类型结合的新型水驱特征曲线,和经典的水驱特征曲线完全等效的一种水驱特征曲线表达式,并对新型特征曲线的形状和性质做了研究。通过实例分析,所建立的新型水驱特征曲线与实际数据拟合相关性更强,结果更可靠。
Water flooding characteristic curve method is an important one to predict water flooding deliverability and recoverable reserve.At the present,the researchers both home and abroad have studied and established tens of expressions for water flooding characteristic curve.All the curves are hard to be used for quantitatively describing the whole process of oilfield development due to the complexibility of the development,they are only suitable for a certain period.Based on several existing new types of water flooding characteristic curves,the new types of water flooding characteristic curves are presented in this paper by combining the second kind of water flooding curve with the tenth kind of water flooding curve and the C kind of water flooding curve with the tenth kind of water flooding curve,the shape and feature of the characteristic curves are studied.The established curves are better matched with practical data,results are more reliable.
