为了进一步提高窄条状断块油藏开发中后期剩余油挖潜水平,对剩余油定量评价的方法和老井开窗侧钻辅以水平井组合挖潜技术进行了研究。在剩余油定量研究的基础之上,从窄条状断块油藏的地质特点出发,分析了油藏的开发特点以及中高含水期剩余油分布特点,着重阐明了与这类油藏地质条件和开发特点相适应的剩余油定量评价新方法和老井开窗侧钻辅以水平井组合挖潜的主要方法和配套技术系列。通过在AF油田的成功应用,进一步证明了老井开窗侧钻辅以水平井组合挖潜技术是提高窄条状断块油藏开发水平的有效手段,具有较好的应用前景。
In order to further improve the tapping potential of remaining oil in the development of narrow strip fault reservoirs, the method of quantitatively evaluating the remaining oil and the co-drilling technology of the old well with the horizontal well were studied. Based on the remaining oil quantitative study, based on the geological characteristics of the narrow strip fault block reservoir, the characteristics of the reservoir development and the distribution characteristics of residual oil in the middle and high water cut stages are analyzed, and the relationship between the geological conditions and Development of new features consistent with the quantitative evaluation of remaining oil and the old hole fenestration with a combination of horizontal well to tap the potential of the main methods and supporting technology series. Through the successful application in the AF oilfield, it is further proved that the combination of the horizontal well combination tapping technology with the old hole fenestration and lateral drilling is an effective means to improve the development level of narrow strip fault reservoirs, and has a good prospect of application.
