摘要
综合考虑不同含水饱和度下油水流动能力的不同和常规的黏度、地层系数、压力等参数对多层合采油藏产量劈分的影响,并且根据生产动态数据,应用多元线性拟合的方法,计算油水相对渗透率,提出新的动态分析相渗产量劈分法。新方法不仅考虑了黏度、地层系数等因素,最重要的是结合了以动态数据多元线性拟合为基础的相渗曲线。将实例的数值模拟计算结果和常规地层系数法劈分结果进行对比发现,应用该方法进行产量劈分的结果精确度高,适用性强。
Conserding the assessment of different fluid ability of oil and gas under different water saturation, viscosi- ty, KH, pressure, et al, which have an influence on interbed reservoir＇s production splitting, and based on the production dynamic data, this paper uses the linear fitting method to calculate the relative permeability curve, and points out a new dynamic analytic relative permeability production splitting method. In the new method, not only the general parameters such as viscosity, KH, pressure is considered, but also the relative permeability is based on analysis of dynamic data. Compared with to the KH method and the simulation method splitting result, this paper indicates this new method are more accurate than KH method.
