根据对四川盆地JLS地区须二段储层裂缝形成机制、发育规律和构造形迹的认识,探索出了一套预测背斜型构造裂缝发育带的裂缝性储层预测方法,即利用3D Move技术刻画构造两翼裂缝的发育特征,同时结合构造形迹分析,利用构造解析技术对高点和鞍部裂缝发育规律进行分析。该方法克服了3D Move裂缝预测技术对某些特殊构造部位如高点和鞍部裂缝发育情况不能有效识别的缺点,对储层裂缝预测的结果更逼近真实发育情况。

According to the analysis of the fracture forming causation and the fracture developing pattern and research of the structure evidence, the paper approach a method of predicting the reservoir fracture sets, which is using the tectonic of 3D Move to reveal the character of fracture sets development in the two wingers of JLS anticline, meanwhile incorporating the analysis of the structure evidence to reveal the character of fracture sets development in the high and the saddle of JLS anticline. This method surmount the defect of 3D Move can't predicting the reservoir fracture sets in the high and the saddle of anticline, by using this method, the real reservoir fracture sets can be found.
