We conclude the reservoir is of complex pore - cave - fracture type . 5 . the karst reservoir is studied by paleography , leaching time , hydrological regime , lithofaces - paleography , combined with outcrops and drilling data , the karst reservoir model is established 8 、本区岩溶储层的空间分布呈带状，非均质性强，并受水动力带、岩性、沉积相、构造、风化剥蚀持续时间和古地形的影响。
2.
On the basis of depositional studying of single well , concluding lithofaces - paleography of every formation : yeli - liangjiashan formations deposit in restrained sea ; lower majiagou formation early in tidal flat and late in restrained platform ; upper majiagou formation early in tidal flat and late in open sea ; fengfeng formation early in tidal flat and late in open sea 指出冶里组?亮甲山组以局限海沉积为主，早马家沟早期潮坪发育，晚期为局部台地，晚马家沟早期仍有广泛的潮坪发育，晚期则以开阔海为主，峰峰期早期潮坪广布，晚期则以广泛发育开阔海为主。
