靖安油田五里湾长6油藏属于典型的低渗透整装油藏,于1996年采用反九点面积注水井网大规模开发,开发过程中形成了以“先建立有效的驱替系统、再保持温和的注水格局”为核心的注水开发技术体系,实现了连续十一年的低含水开发,2007年油藏进入中含水开发阶段,开发矛盾加剧。因此,油田开发迫切需要不断完善成熟技术、攻关瓶颈技术、研究前瞻技术,逐步完善适合不同开发阶段的配套稳产技术体系,实现油藏的持续高效开发。
Chang’an Wulianwan 6 reservoir belongs to a typical low-permeability unitary reservoir. In 1996, it used a large-scale development of an injection well pattern with an area of 9 o’clock. During the development, a well-known displacement system , And then maintain a moderate pattern of water injection "as the core waterflooding technology system to achieve a continuous 11 years of low water-cut development, in 2007 the reservoir into the water-based development stage, the development of contradictions intensified. Therefore, there is an urgent need to constantly improve the mature technology, research the bottleneck technology, research the forward-looking technology, and gradually improve the supporting stable production technology system suitable for different development stages so as to realize the continuous and efficient development of the reservoir.
