江苏油田单井可采储量计算方法研究

随着油藏经营管理和油田可采储量管理的精细化,现有的可采储量评价方法难以准确、及时地反映当年投入增加可采储量的时效性。从可采储量精细化管理需要出发,结合江苏油田实际生产资料,选用递减法对江苏油田单井可采储量进行了计算,分析了影响单井可采储量的主要开发指标,在此基础上建立了相应的不同类型油藏、不同含油层系单井可采储量预测模型,并用实例验证了模型的适用性。

Research on the calculation method for single- well recoverable reserves in Jiangsu Oilfield

With refining of reservoir operation management and oilfield recoverable reserves management, timeliness of increased recoverable reserves can not be reflected by the current evaluation methods for the recoverable reserves. From the needs of fine management of recoverable reserves, combined with actual production data of Jiangsu Oilfield, a descending method was selected to calculate single - well recoverable reserves, and analyse the main influencing factors. And on the basis of that, prediction models of single - well recoverable reserves for different type reservoirs and oil - bearing series were established. And examples were taken to verify the models.
