摘要
Carbonate rock reservoir in Sichuan basin is one of the important marine reservoirs in China.Analysis of macro and micro characteristics of silica materials in carbonate rocks in Sichuan basin show that the silica materials are mainly interbeded,mixed together with the carbonate rock,filled in the carbonate or replace the carbonate.Silica which is interbeded with the carbonate rock,filled in the carbonate rock or replace the carbonate rock is mainly derived from volcanic eruption but the late settlement mechanism is different.Silica mixed together with the carbonate rock is derived from terriginous debris and is of source indication..The interbedding,filling and metasomatic silica plays both building and destruction role on reservoir but the mixed silica only destruction role.
