对于井网已经固定的水驱油藏,长期开发之后流线已经固定,注入水的波及受到限制,不利于进一步提高采收率。在营6单元井网方式和剩余油分布规律及控制因素研究的基础上,通过油藏数值模拟技术和油藏工程方法,建立营6断块油藏类型条件,不同产注结构、不同砂体分布形态、不同储层物性、不同的剩余油分布形态、不同流体性质组合下的最佳配产配注模型,制定配产配注模型的技术政策界限和开发技术界限,最大限度的提高单砂体的水驱控制程度和动用程度,改善开发效果,建立配产配注系统优化模型,广泛进行现场应用,并总结现场应用效果,最大化提高储量动用和水驱波及体积,对指导该类油藏挖潜剩余油,提高油藏水驱采收率具有重要的意义。
For a well-established waterflooding reservoir, the flowline has been fixed after long-term development and the inflow of water is limited, which is not conducive to further enhancing oil recovery. Based on the study of well patterns and residual oil distribution patterns and control factors in Ying 6 unit, by means of reservoir numerical simulation and reservoir engineering methods, the reservoir type conditions of Ying 6 fault block are established, and different pay structure and different sand bodies Distribution patterns, physical properties of different reservoirs, distribution patterns of different remaining oil, the optimal allocation model with different fluid properties, formulating technical policy limits and developing technological boundaries for the allocation of injection model, and maximizing the production of single sand The degree of waterflood control and utilization of the body, to improve the development effect, to establish a system of matching with dispensing system optimization model, a wide range of on-site applications, and summed up the field application effect, maximize the use of reserves and water drive wave volume, to guide the oil It is of great importance to excavate potential residual oil and improve waterflood recovery.
