Abstract

The forming conditions of Chang 6 reservoir in Anding area of Zichang Oilfield are studied. Chang 6 reservoir is typical low and ultra-low permeability reservoir, with single source-reservoir-seal assemblage. Lacustrine source rocks provided resource for the oil and gas generation, and flood plain facies and paludal facies mudstone supplied cap rock for the reservoir accumulation. The results show that Chang 6 reservoir is typical lithologic reservoir, and the hydrocarbon enrichment is dominated by reservoir properties, lithologies and lithofacies. Both the sedimentary facies zones and reservoir properties control the hydrocarbon distribution of Chang 6 reservoir.

Key words： Yanshan period structure; paleotectonics; Lenghu structural belt; residual depression; Lower Jurassic; northern Qaidam Basin
