油藏动态监测新手段

A new approach to reservoir monitoring

过套管电阻率测井是近年来发展的一种新的油藏监测技术,文中对比了过套管电阻率测量结果与常规侧向测井电阻率的对应关系,分析了过套管电阻率测井在寻找未动用或/和漏失油层、注水开发油田已开发储层的水淹程度及开发过程中储层含油性变化的评价方面表现出的优势,讨论了过套管电阻率测井资料求剩余油饱和度的方法。对过套管电阻率测井资料的分析表明,在充分考虑过套管电阻率各种影响因素并进行适当校正的情况下,过套管电阻率测井可以实现对复杂储集层的评价与动态监测,它将为油藏的动态描述与管理提供一种直观有效的方法。

Through casing formation resistivity(TCFR) has been developed for reservoir monitoring in recent years.The paper contrasts TCFR data and lateral resistivity logging,analyzes the advantages of the TCFR on judgment for un-development reservoirs/overlooked reservoir,injection development levels,and discusses the method for residual oil saturation in reservoir by TCFR.Analysis on through casing resistivity logging data shows that,taking full account of various factors for TCFR and making the corresponding appropriate correction,the technology for through cased hole formation resistivity logging can be applied to complex reservoir evaluation and dynamic monitoring.Thus that will provide an intuitive and efficient way for dynamic reservoir description and reservoir management.
