肇州油田芳169区块断层封堵性研究

Study on fault sealing in Fang 169 block of Zhaozhou Oilfield

以肇州油田芳169区块复杂断块油田为例,在已有勘探开发资料的基础之上,利用Yielding等人(1997)提出的泥岩断层泥比率(SGR)方法,结合区内实际地质情况,有选择地对区内2条控制已知油藏关键性断层的封堵条件进行了初步探索。结果表明:定量分析得出的评价结果与依据开发动态资料分析而得到的结论是一致的。其方法可以尝试对研究区内其它规模相当、性质相似的断层进行封堵性评价,从而为目前的开发及围区的进一步勘探提供决策参数。

Based on the existing exploration and production data of Fang 169 block in Zhaozhou Oilfield, the Shale Gouge Ratio （SGR） algorithm defined by Yielding et al in 1997 is adopted to carry out the preliminary quantitative calculation on two selected typical faults. The result shows that the quantitative analysis results are consistent with the conclusion obtained from production dynamic data analysis. It indicates that this SGR algorithm can be applied to other similar faults in the study area.
