摘要(Abstract)：

根据低渗透油藏储层特点,在室内实验和调研分析的基础上,应用流线积分和单元分析方法,推导了基于渗透率压力敏感的四点法、五点法和反九点法面积井网产量计算方法。通过与麦斯盖特法对比,证明了所建方法的正确性和可靠性。应用该方法研究了不同渗透率储层压力敏感对各井网产能的影响,并分析了特低渗透储层不同压力保持程度对生产能力的影响。基于压力敏感的面积井网产量计算为低渗透油田的产能设计和开发指标预测提供了有效方法。
Based on the characteristics of the low-permeability oil reservoirs and analyses of the laboratory experiments and investigation,the calculating methods for 4-spot,5-spot and inverted 9-spot areal well patterns with the permeability and pressure sensitivity are deduced with the help of the methods of flow line integration and unit analysis.Comparing with M.Muskat method,the accuracy and reliability of this method are confirmed.The effects of the pressure-sensitivity on the productivity for the oil reservoirs with different permeabilities are researched.And moreover the influences of the pressure-sustained degree on the productivity of extra-low-permeability reservoirs are also figured out.The calculating methods for the production of areal well patterns based on the pressure sensitivity have provided effective ways for the productivity design and development index prediction.
