Fracture styles are consisted mostly of structural fracture, which not only make up the principal permeability contributor, but also control porosity distribution in the vertical and planar section. The matrix porosity has good correlation with the fracture's development in the Carboniferous bioclastic limestone member. High porosity zones are commonly found in fracture well developed parts such as structure axes, low porosity zones in less fracture structure nek.

裂缝以构造缝为主，裂缝不但是储层渗透率的主要贡献者，而且控制孔隙在垂向及平面上的分布：在纵向上，裂缝发育段也是基质孔隙发育段；而平面上，构造高部位等裂缝发育处孔隙度也相对较大，而在构造鞍部裂缝不发育区，孔隙度也低。
