摘　　要：雾迷山组底水油藏已经进入特高含水、高采出程度开发阶段,绝大部分油井发生水淹,可采储量计算结果表明油藏还有相当大的増油潜力。根据油藏的特征建立底水油藏单井渗流模型,算出该油藏高含水阶段的合理井网密度。任9、任11山头的井网密度较低,在其腰部和脊部可以侧钻大斜度井或水平井;任6、任7山头的井网密度较高,重点应该放在合理调整注采井的关系上。Wumishan reservoir is a bottom-water-drive reservoir, and it is in high water cut stage and of high degree of reserve recovery. At present, most producers have been submerged by water.So it is difficult to recover the remaining oil. The calculation results demonstrate that the reservoir has remaining oil in ground. Based on the characteristics of the reservoir, a single well flow model of partly opened bottom-water-drive reservoir is applied to obtain the reasonable well spacing density. The well spacing on the top of buried hill Ren 9 and Pen 11 is low. High angle deviated wells and horizontal wells are recommended to be set on the buried hill slope and buried hill ridge. The well spacing on the top of buried hill Pen 6 and Ren 7 is high. It is necessary to adjust the relationship of injectors and producers.
