钟市油田潜四段层系细分调整研究

On Subdivision and Adjustment of Qian-4 Member Bed Series in Zhongshi Oilfield

钟市油田潜四段含油层组多、油砂体多,储层非均质性严重。针对钟市油田潜四段储层非均质性引起的平面、层间和层内矛盾,以油砂体为单元,利用油藏数值模拟手段进行了剩余油分布规律研究。总结剩余油在纵向和平面上的分布特点,根据储层非均质性对油田开发的影响和剩余油分布规律,对钟市油田潜四段进行了层系细分开发调整。研究成果表明:多层叠瓦状非均质性较强的油藏适合采用层系细分调整技术进行开发,对同类型油藏的研究具有指导意义。

There are many oil layer groups and oil sand bodies in Qian-4 Member in Zhongshi Oilfield whose reservoir is lack of homogeneity.Aiming at its anisotropism,this paper,taking oil sand body as a unit,studies the rule of remaining oil distribution by means of numerical reservoir simulation,concludes the distribution characteristics of remaining oil vertically and laterally and accordingly carries out subdivision and adjustment of bed series.Research result shows that multiple stack tile-shaped reservoir with strong anisotropism is fit for bed series subdivision and adjustment technology.
