CONDITIONS FOR SICHUAN BASIN TO TRAP TRIASSIC BRINE

Lin Yaoting (No.2 Geological Party of Southwest Bureau of Petroleum)  
Sichuan basin is known for Triassic brine to have be widely spread with rich resources, excellent quality, higher industrial value and a long tapping history. Detrital rock and carbonatite stand as two important brine-trapping rocks because of lower porosity, lower osmosis and hence higher compactness. However, these do little with movement and enrichment of the brine so its preservation is controlled essentially by the faults and fissured belt of the brine-bearing beds after they were destroyed by post-deposition structural stress, a leading factor that led to higher enrichment and output of the brine.
