高效井前期利用对三次采油的影响研究

在考虑井网演变趋势的基础上，本文利用三次采油井网，对目前注采不完善区域及断层附近等剩余油富集区先打井进行水驱挖潜，后转为三次采油井开发，以实现油田的高效开发。采用数值模拟技术研究高效井前期利用对后期三次采油的影响，结果表明：高效井前期利用三次采油的最终采收率比无高效井三次采油高约0.11%，增加可采储量达1.3?04t。由于高效井的前期利用可增加可采储量，因此证明了高效井的前期利用是正确的、有价值的。

Research Effects of Prophase Using of Efficient Wells on EOR

By considering into the evolution tendency of well networks, this paper adopted the method of drilling wells, used in EOR, in advance. To achieve the efficient development, water flooding was firstly carried out to exploit the remaining oil, distributed in the regions where injection-production imperfect happened, as well as in the areas near the faults and so on, and then wells used in EOR were exploited. This paper mainly used numerical simulation technology to research the effects of prophase using of efficient wells on EOR. Results showed that prophase using of efficient wells made the ultimate oil recovery of EOR 0.11 percent higher than that without prophase using of efficient wells and recoverable reserves increased by 1.3?04tons. Due to prophase using of efficient wells can increase recoverable reserves, it was proved that prophase using of efficient wells was correct and valuable.
