摘要/Abstract

摘要： In order to evaluate whether the reserve-production ratio of an oilfield is reasonable or not, according to the definition of reserve-production ratio, the relationship among production decline rate and liquid production and the relationship between production decline rate and water cut, the paper establishes the relationships between the reserve-production ratio and liquid production increasing rate, water cut increasing rate and reserve-production equilibrium coefficient, respectively, and predicts the trends of reserve-production ratio in different development modes. Additionally, the paper establishes an annual reserve-production ratio formula under the ideal conditions and charts of rapid prediction of reasonable reserve-production ratio, divides the reserve-production ratio at the limit water cut into 4 categories including reasonable, relative reasonable, unreasonable and extremely unreasonable reserve-production ratio and then determines the reasonable reserve-production ratio. Applying this method into a block and assuming that other conditions remain unchanged, the reserve-production ratio is already negative when the water cut reaches 96.2%, indicating a relatively low reserve-production ratio. Finally, the reasonable reserve-production ratio is determined as 8.2, which provides new references for reasonable reserve-production ratio limit determination in oilfields and countermeasures for development plan adjustment based on the rationality evaluation of the current reserve-production status of oilfields.
