欧力坨油田属低渗透油藏,随着天然能量开采时间的延长,地层压力逐年下降,地下亏空严重。针对断块天然能量不足及地层压力较低的特点,采取注水开发方式,并对注水区块实施综合治理,提高水驱储量动用程度,改善水驱效果,油田油井注水见效明显,区块日产液量油量稳中有升,开发效果得到明显改善,实现了油田的稳产和高效开发。 Oli Tse Oilfield is a low permeability reservoir. With the extension of natural energy mining time, the pressure of formation decreases year by year and the underground is in serious deficit. In view of the natural energy deficit of fault block and the low formation pressure, the waterflooding development mode was adopted, and the comprehensive treatment of waterflooding blocks was implemented to improve the utilization of waterflooding reserves and improve the waterflooding effect. The amount of oil steadily rose, the development effect has been significantly improved, to achieve a stable and efficient oilfield development.
