提出一种新的油藏动态分析方法 ,该方法以大系统理论方法为依据 ,将油藏视为由注水井、采油井与储层组成的大系统 ,运用概率统计、控制理论、随机信号处理等理论方法 ,通过建立水驱油评价模型、井间流体干扰评价模型、单井生产状况评价模型 ,整体分析油藏不同开发时期地下油水分布状况、水驱效果及泄油状况、弱排油区或死油区、油井生产状况等 ,及时提供制定措施的依据 ,挖掘剩余油 ,提高采收率。实际应用表明 ,其预测分析结果与实际吻合较好
A new method for dynamic analysis of reservoir is proposed, which is based on large-scale system theory. The reservoir is regarded as a large system composed of injection wells, production wells and reservoirs. Probability statistics, control theory, random signal processing And other theoretical methods, through the establishment of water flooding evaluation model, cross-well fluid disturbance evaluation model, single well production status evaluation model, the overall analysis of reservoir development in different periods of underground oil and water distribution, water flooding effect and drainage conditions, weak drainage area Or dead zone, production status of oil well, etc., and timely provide basis for formulating measures to tap residual oil and enhance oil recovery. The practical application shows that the predictive analysis results are in good agreement with the actual situation
