摘　　要：针对人造高压油藏开发没有统一的开发适应性筛选标准及筛选方法的问题,引入木桶效应基本原理和内涵,提出人造高压油藏木桶效应开发原理。通过系统分析人造高压油藏各层面的木桶效应内涵,得到高压流场的特征参数、内在基础和外部动力之间的关联性。提出注采井间内外区渗透率比值、注采井间井距与内区半径比值、临界注入压力、井网均衡程度4个筛选指标,给出人造高压油藏开发适应性筛选标准,建立人造高压油藏开发适应性筛选方法。通过对M区块人造高压油藏开发适应性筛选实例应用和现场监测发现,M块适合采用人造高压油藏开发技术。There is an obvious lack of unified screening standard and screening method for developing adaptability of artificial high-pressure reservoirs currently.In view of this,the development principle of barrel effect in artificial high-pressure reservoirs was put forward using the basic principle and connotation of barrel effect in the present work.By systematically analyzing the connotation of barrel effect in artificial high-pressure reservoirs,the correlation between characteristic parameters,internal basis and external forces of high-pressure flow field was obtained.And four screening indexes were proposed:ratio of inner zone permeability to outer zone permeability between injection-production wells,ratio of injection-production well spacing to inner zone radius,critical injection pressure and well pattern equilibrium degree.The adaptability screening criteria for artificial high-pressure reservoirs development was also proposed.And the adaptive screening method for artificial high-pressure reservoir development was established.The results of the application of this method and the reservoir monitoring data of Block M show that Block M is suitable for artificial high-pressure reservoir development technology.
