水驱特征曲线是用来预测水驱油田的产量及可采储量的重要方法。国内外学者先后提出了很多种水驱特征曲线的表达式。这些水驱特征曲线在使用过程中至少要求油田稳定生产一段时间或措施后生产一段时间才能使用,而只适用于某一特定的稳定生产阶段,却不能对整个开发阶段效果进行评价。因此,在分析一些基本水驱特征曲线及应用的基础上,提出一种新型的关系式简单、参数求解容易的水驱特征曲线,可以计算阶段可采储量和对油藏或单井在储层改造中的效果进行评价,可以分阶段进行评价,实用性更强。
The waterflooding characteristic curve is an important method for predicting the production and recoverable reserves of a waterflooding oilfield. Domestic and foreign scholars have put forward a lot of water-driven characteristic curve expression. These waterflooding characteristic curves require at least the oilfield to be used for a certain period of time or measure after production for a period of time during its use, but only for a specific stable production stage, but can not evaluate the effect of the entire development stage. Therefore, based on the analysis of some basic waterflooding characteristic curves and their applications, a new type of waterflooding characteristic curve with simple relational equation and easy parameter solving is proposed, which can calculate the recoverable reserves of reservoirs, Evaluation of the effect of transformation, can be evaluated in stages, more practical.
