Title: Reservoir Characteristics and Control Factors of the Middle Jurassic Lianggaoshan and Lower Shaximiao Formations in Central Sichuan
Abstract: This paper deals with reservoir characteristics and control factors of the Middle Jurassic Lianggaoshan Formation and Lower Shaximiao Formation based on lithologic characteristics,micro-area and experimental analysis of samples from outcrops and drilling cores in the central Sichuan basin.Study of mineral composition,structural feature,interstitial matter and physical property indicates that pore-fracture is the main reservoir type,the secondary solution pore and fracture are the main pore space.The reservoir was controlled by sedimentary facies,source direction,diagenesis,denudation,tectonic disruption and so on.Sedimentary microfacies and source direction are environment basements of the reservoir,while solution and tectonic fracture are the key factors that improve the reservoir.Diagenesis such as compaction,pressure solution,cementation and replacement are disadvantages for the reservoir.
