摘要
This paper studies and evaluates the reservoir characteristics of the Da’anzhai segment of Lower Jurassic Ziliujing Formation of Quxian area in the northeast of Sichuan Province. This reservoir can be classified to the typical low-porosity and-permeability fractured one.The former one has larger oil and gas exploration potential than the latter one.In addition,the reservoir of the Da’anzhai segment formed in the environment of the shelly beach,which has undergone multi-type and multi-stage diagenetic changes.The destructive diagenesis,especially the compaction,has made most pores lose,but the constructive diagenesis including the dissolution and post-tectonic disruption has improved the reservoir performance,which is a key factor in the formation of tight reservoirs in study area.
