摘要
Abstract
Based on the principle of injection-production balance,the relationship between formation pressure drop and injection-production ratio during stable production of oil reservoirs is derived using the material balance equation.Key parameters are obtained by fitting field data,and a method for determining injection-production ratio based on reasonable formation pressure drop is proposed,providing a basis for production management in the later stage of oil reservoir development.Taking four development units in a certain oilfield as application examples,the reasonable injection-production ratios were calculated to be 1.23,1.20,0.90,and 1.06,respectively.The case analysis shows that this method is simple to calculate and the results are reliable.It can provide theoretical basis for the adjustment of water injection development in sandstone reservoirs with ultra-high water content,and has practical value for optimizing oilfield injection and production management.关键词
