加密调整井产量变化对油田产量递减率的影响

Influence of production variation of infilling adjustment wells on oil field production decline

为了掌握油田产量递减规律 ,给出了油田递减率的计算公式 ,分析了油田产量递减率与加密调整井产量及其递减率变化的关系 .油田在某一阶段内的产量总递减率等于各类井结构递减率之和 。

To grasp the variation regulation of oil field petroleum decline, this paper provides a formula for caculating the oil field petroleum decline rate, it also analyzes the relationship among the decline rates and the productions of infilling adjustment wells and the variation of the decline rate. The gross decline rate of oil field production in a stage is equal to the sum of structural decline rates for different kinds of wells,that is, it is equal to the sum of the ratios of initial stage production to the gross production multiplied by the corresponding decline rate for different kinds of wells.
