摘要

摘要: CO₂驱油是3次采油提高采收率的一项重要手段,其驱油前后油藏动态监测评价工作十分重要,目前国内外尚未形成一套成熟的CO₂驱油动态监测评价技术系列。苏北盆地溱潼凹陷CS油田Et组油藏开展了CO₂混相驱先导试验工作,通过运用井间示踪、试井、吸水吸气剖面、产液剖面、剩余油饱和度及油气水性质等动态监测技术及相应监测技术的组合,满足了复杂断块低渗透油藏开展CO₂混相驱试验方案的编制、试验参数的优化调整及效果评价的需求。

Abstract: Oil displacement by CO₂ injection is an important measure to enhance tertiary oil recovery,and it is very important to monitor and evaluate reservoir performance pre-and post-oil displacement.However,there is't a series of matured performance monitoring and evaluating techniques for oil displacement by CO₂ injection at home or abroadyet.Pilot tests of CO₂ miscible displacement have been carried out in Et formation reservoir of CS Oilfield in Qingtong Depression of the Subei Basin.Through combination of performance monitoring techniques(such as interwell trace,well test,water and gas injection profile,produced fluid profile,remaining oil saturation,and properties of oil,gas and water) and relevant monitoring techniques,it meets the requirements of low permeability oil reservoir in complex fault block to prepare testing program for CO₂ miscible displacement,optimize and adjust test parameters and evaluate the effects.
