摘要
九龙山气田须二下亚段气藏是形成于超低孔、渗型的储集岩层中的致密气藏，裂缝的发育与否对单井气产量起着控制作用。从储集层岩石的力学性质、构造形态以及电测曲线解释结果等方面入手，对该气藏裂缝在平面上的发育状况进行了讨论，划定了４个不同的裂缝发育分区。这一结论对该气藏开发调整方案的设计和实施将有很好的参考作用。
Xu Ⅱ lower section gas pool in the Jiulongshan gas field is a tight gas pool formed in super low porosity and permeability reservoir rocks. The gas well capasity there is mainly controlled by the development state of fractures. Based on the mechanical property of reservoir rocks, structure attitude and the result of electric log interpretation, the development state of fractures of the pool on plane is discussed. Four different development state zones are also created by the multi information coincidence evaluation method.
