Base on core observation and grain size analysis, and under associated consideration of logging trace characteristics, Chang8 reservoir in study area is classified into three sedimentatal microfacies, subsea river, mouth bar and river flank.3.The mian diagenesis in study area are: mechanical compaction, cementation, metasomasis and denudation in late diagenetic phase.4. In allocation of reservoir macroscopic heterogeneity, more heterogeneticer reservoir, class 1 and class 2, mainly locate in the center of subsea river or crook and divaricate of the river; class 3 and class 4 mainly locate in river flank, and the physical property of these locality are better.5. Diagenesis of reservoir have influence on the pore structure which influences the reservoir microscopic heterogeneity. The better the pore structure is, the slighter the reservoir microscopic heterogeneity is; on the contrary, the reservoir microscopic heterogeneity is serious.

本次研究所取得的主要成果及熟悉有：1、将合水地区长8储层细分为6个小层：长8_1~1、长8_1~2、长8_1~3、长8_2~1、长8_2~2和长8_2~3.2、依据岩心观察和粒度分析，并结合测井曲线特征，研究区长8储层分为水下分流河道、河口坝和河道侧翼四种沉积微相。3、研究区主要经历的成岩作用有：机械压实和压溶作用、胶结作用、交代作用、晚成岩期溶解作用。4、从宏观非均质性平面展布特征来看研究区宏观非均质较强的1类和2类区主要分布于水下分流河道中间或河道拐弯和分又处。3类和4类往则主要分布于水下分流河道侧翼，这些地方储层均质性相对较好。5、储层成岩作用影响储层的孔隙结构，储层的孔隙结构又对储层的微观非均质性有不同程度的影响，孔隙结构越好，则储层的均质性越好，储层的孔隙结构差，则非均质性强。

When the fault throw is relatively small, the shale gouge ratio and clay smear potential are relatively large and shale smear is strong. In addition, the coal layers on both sides of the fault are mainly juxtaposed against shale. Therefore, shale smear and juxtaposition play a key role in the sealing. In contrast, when the fault throw is relatively large and shale smear is relatively weak, juxtaposition is unfavorable for sealing. However, the mylonite resulted from strong cataclasis can act as a seal of the coals. The cementation resulted from underground water activity is of great significance to the sealing ability of the fault. Mylonitic coal layers resulted from faulting occur on both sides of the fault. They are unique reservoirs with low permeability and high displacement pressure and their scales depend, to some extent, on the fault throw, fault properties, the hanging wall and footwall.

结果表明：①当断层落差较小时，断层泥比率和泥岩涂抹潜势值较大，泥岩涂抹效应强烈，且与断层两侧煤层对接的岩石主要为泥岩类，此时起封闭作用的主要为泥岩涂抹作用和断层两侧岩性配置关系；②当断层落差较大，泥岩涂抹作用较弱时，对接越不利于封闭形成，但碎裂作用强烈，沿断层两侧形成的糜棱岩对煤层起到了封闭作用；③地下水活动导致的胶结作用对整个断层的封闭具有重要的意义；④断裂作用形成的糜棱煤沿断层两侧分布，此糜棱煤带是一种低渗透、高排替压力的特殊储层，其规模与断层的落差、性质、上下盘都有一定关系。

The medium-grained sandstones and medium-fine-grained sandstones form good reservoirs and the poststones medium reservoirs, while siltstones form poor reservoirs and pelitic siltstones poorest reservoirs. Sand bodies mostly develop in sand-flats, tidal channels and distributary channels of braided stream delta microfacies. The reservoir rocks of sand-flat and tidal channel are best with the physical property. Diagenesis such as compaction, cementation and dissolution has strongly reformed the reservoir rocks and the late dissolution has greatly improved their porosity and permeability.
