研究结果表明，本区储层砂岩较低渗透率的主要成因是成岩期各种自生矿物的充填和胶结作用。

The results indicate that the forming mechanism of the low permeability in this area is the filling and cementation of autogenetic mineral during diagenesis.

粘土包壳作为石英晚期胶结作用的抑制剂可能是特别重要的。

Clay coats can be particularly important as inhibitors of later quartz cementation.

方解石胶结是砂岩储层最重要的一种成岩作用，非常发育和广泛。

Calcite cementation is one of the most important diagenesis in sandstone reservoir, extraordinarily growing and widespread.
