- •
The Taiyuan Formation consists of lowstand systems tracts (LST), transgressive systems tracts (TST) and highstand systems tracts (HST).
- •
The LST sandstones were mostly deposited in delta plain, the TST and HST sandstones in delta front and shoreface to foreshore.
- •
The Taiyuan sandstones suffered from extensive compaction and cementation with poor reservoir quality.
- •
The LST delta plain sandstones have a better reservoir quality than the delta front to shoreface and foreshore sandstones of TST and HST.
- •
The sandstone reservoir quality was controlled by sequence stratigrahy framework, depositional facies, grain size and diagenetic alterations.
