摘要
本文在对油田单井提液理论和应用现状进行分析的基础上,研究并提出一种用于判断单井最佳提液时机的新方法。该方法首先对单井动态生产数据进行甲型处理,并通过甲型水驱曲线拟合相对渗透率曲线的油相、水相指数和水油流度比;再由此作出无因次采油、采液指数曲线图并进行最佳提液时机分析。所提出的理论和方法对油田开发把握单井提液措施的有利时机,提高作业成功率具有一定的实际应用价值。
In this article, we studied the basic theories and application actualities of increasing liquid production for single well. Based on it, we analyzed and developed a new kind of method to estimate the optimal increasing liquid production opportunity for single well of different geological, reservoir character- istics and producing characteristics. Firstly, the dynamic production data are filtered by use of the first wa- terflood characteristic curve denoise. Secondly, we could work out a kind of waterflood characteristic curve and relative permeability curve of single well. Then, analyze the dimensionless productivity/fluid produc- tivity indexes curves combined with the static data and estimate the optimal increasing liquid production opportunity for single well. The theories and methods proposed in this article have certain practical appli- cation value for us to grasp the opportunity of increasing liquid production for single well and increase the success probability of operation.
