摘要

为了研究致密大模型注水吞吐采油规律,建立大模型多点抽真空饱和水和异步注采饱和油的物理模拟方法,结合自主研发的大型露头致密岩样注水吞吐物理模拟实验系统,创建了致密露头模型注水吞吐物理模拟方法。针对鄂尔多斯致密储层特性进行了致密油藏注水吞吐方式的探索研究。结果表明,致密露头模型注水吞吐物理模拟方法能够真实地模拟致密油藏注水吞吐过程中的渗流规律。在注水吞吐物理模拟实验中,渗透率是影响吞吐开发效果的主要影响因素,造成吞吐采出程度在5.5%~17.1%变化。
        For investigating the recovery mechanism of water injection huff and puff process,with the use of large-model multipoint vacuum saturated water and asynchronous injection-production saturated oil physical simulation experiment methods,and combining with self-developed physical simulation experimental system of cyclic water injection for large tight outcrop samples,a corresponding method is set up.On this basis,aiming at the characteristics of tight oil reservoir in china exploration and research were carried out on cyclic water injection mode in tight oil reservoirs.The results show that the physical simulation experimental method can be used to really simulate the dynamic porous flow of cyclic water injection in tight oil reservoirs.In the experimental process,permeability is the main influencing factor to influence the effect of huff and puff development,which cause the recovery percent of huff and puff in the range of 5.5%-17.1%.This research achievement can provide a certain technical support for effective development of tight oil reservoirs.
