王73区块天然能量差,区块投入开发后,一直弹性开采,递减较大,目前大部分井供液较差,动液面位置在1000m左右,采油速度0.28%,采出程度3.14%,开发水平较低。为改善油藏的开发效果,制定王73区块的配产配注方案,实现注水开发,完善注采井网,旨在提高水驱储量的控制程度,提高采收率。
Wang 73 block natural energy is poor, the block after the development of the project, has been flexible mining, decreasing larger, most of the current poor liquid supply, moving liquid surface location of about 1000m, oil production rate of 0.28%, 3.14% recovery level, Low level of development. In order to improve the development effect of the reservoir, the scheme of allocation and distribution of injection for Wang 73 block was formulated to realize the development of water injection and improve the well and well pattern of injection and production so as to increase the control of waterflooding reserves and increase oil recovery.
