柏各庄油田唐2×1区块侏罗系储层裂缝特征研究

Study on Jurassic reservoir fractures of Tang2×1 area in Baigezhuang oilfield

应用常规测井资料 ,结合岩心描述 ,对柏各庄油田构造裂缝的发育部位和发育方位进行识别 ,采用有限元法数值模拟对裂缝古应力场进行定量预测。结果认为 ,侏罗系储层裂缝比较发育 ,裂缝方位为NE向。该方法是研究本区构造裂缝的有效方法 ,对寻找流体的有利聚集场将起到重要的作用。

The growing part and azimuth of structural fractures in Baigezhuang oilfield has been identified by using conventional logging data and core description.Palaeostress field of fractures has been quantitatively predicted through finite element numerical simulation.The result is that Jurassic reservoir fractures were relatively developed in NE azimuth.This method is efiective for studying structural fractures of this area,and will be helpful for finding favorable fluid accumulations.
