摘要: 准确预测低渗透油藏的单井产能是合理开发低渗透油藏的重要决策依据。根据长庆油田低渗透油藏的孔渗特征,利用数值模拟方法对影响产能的储集层因素进行了敏感性计算,通过正交分析确定出单井产能与油层厚度、渗透率以及含油饱和度的关系,提出多因素的单井产能预测公式。经实际验证,方法简便、可靠。

Abstract: Accurately predicting the well productivity in low permeability reservoir is crucial to reasonably develop it with efficiency. According to the porosity and permeability characteristics of low permeability reservoir in Changqing oil field, the sensitive analysis on reservoir factors which might affect well productivity by applying numerical simulation is conducted, determine the relationship between the single well productivity and oil layer thickness, permeability and oil saturation with the orthogonal analysis is determined, giving the regression formulae of single well productivity prediction with multi-factors. The method has been proved to be simple, convenient and reliable.

Key words: low permeability, well production, productivity prediction, equation
