中文摘要：
射孔是油气井的主要完井方式之一，不同的射孔参数对井的产能有不同的影响。为科学而准确地预测不同射孔条件下井的产能，利用有限元分析法建立了三维单相油藏渗流数学模型，讨论了有限差分法对模型的求解。针对长庆油田低渗透、低产能的特点，通过数值分析法，分析了不同射开程度对油井产能比的影响，为选择合理的射孔方案，最大程度地提高油井产能提供了理论依据，对指导现场射孔作业有重要的实际意义。
英文摘要：
Perforation is one of major oil and gas well completion method, the different perforation parameter produces to the well can have the different influence. For scientifically accurately forecasting well productivity in different perforation condition, this paper, based on a finite element analytic method, establishes a finite element three - dimensional simulation model and discusses its finite difference solution. In view of the development characteristics of Changqing oil field with low permeability and minor production, through mathematical analytic method, perforation degree influenced to the oil well production rate is discussed. It provides an effective approach to the choice reasonable perforation plan, has important practical significance to the scene perforation work.
