北北块二区萨Ⅲ4-10油层“二三结合”试验区,在二类油层三次采油前这段时间,充分利用二类油层三次采油加密井网,应用层内结构单元研究成果,按三次采油层系,对二类油层首先进行水驱加密调整挖潜,将水驱二次采油与三次采油有机结合起来。为更好地指导后期开发调整,本文对注采井的生产效果进行了细致分析采油井含水变化情况,研究不同类型夹层的渗流遮挡作用,为提高对特高含水期油层动用状况的认识和后续开发调整提供指导。对已经实施的措施井进行跟踪、监测,评价措施效果,为后续开发调整积累经验。
In the period from the third to the third oil recovery of the second type of oil reservoir, the third type of oil well of the second type is used to fully utilize the well pattern of the third oil recovery of the second type and the research results of the in-layer structural elements are applied. According to the tertiary oil production system, the second type of oil reservoir is first flooded with water to adjust and tap the potential, combining the secondary oil recovery with tertiary recovery. In order to better guide the later development and adjustment, this paper analyzes the production effect of injection well and production well and analyzes the change of water in oil production well to study the seepage obstruction of different types of intercalations. In order to improve understanding and follow-up Development and adjustment to provide guidance. We have tracked, monitored and evaluated the measures that have been implemented to accumulate experience for subsequent development and adjustment.
