Study shows that compaction and cementation can play a destructive role in Suining formation reservoir,while dissolution and fracturing can play a constructive role in that.The main facies of Suining formation are ferruginous-shale film,anhydrite,dolomite and calcite.The micro-fracture and grain-edged fracture mainly resulted from compaction fracturing,compaction slipping and tectonic dynamic force greatly improve the reservoir permeability.

研究表明：①对遂宁组储层起破坏作用的是压实作用、胶结作用和交代作用，而溶蚀作用、压裂作用则对储层起到建设性作用；②遂宁组最主要的成岩相组合为铁泥膜－硬石膏－白云石－方解石成岩相；③由压实破裂、压实滑动和构造动力形成的微裂缝、粒缘缝有效改善了储层的渗透性。
