Abstract

Abstract

The Zhuhai Formation and Enping Formation in Baiyun Sag of Pearl River Mouth Basin are important strata for deep oil and gas exploration. Understanding the basic characteristics of deep reservoirs and analyzing the development characteristics and controlling factors of effective reservoirs can provide necessary guidance and support for deep oil and gas exploration to find favorable target layers and target areas. Based on the analyses of petrology and mineralogy, diagenesis, pore development characteristics and sedimentary facies types of deep reservoirs, the basic characteristics of deep reservoirs are clarified. Deep reservoirs are mainly low porosity-low permeability (LL) and tight reservoirs. Compaction is the main reason for the deterioration of deep reservoir, and carbonate cementation and overgrowth of quartz are the main authigenic minerals. Pore types are mainly intergranular dissolved pores and intragranular dissolved pores. Effective reservoirs are mainly LL reservoirs and reservoirs that are better than LL reservoirs. Porosity is generally maintained at about 10%, and permeability varies widely. Sedimentary facies, dissolution and overpressure are the main controlling factors of deep effective reservoir. Medium- and coarse-grained sandstones have better development conditions of primary and secondary pores, higher permeability, weaker porosity reduction by cementation and stronger porosity increase by dissolution. Dissolution is the key constructive diagenesis in deep reservoir, and dissolution pores are the dominate pore type in deep layer. Overpressure conduction is conducive to the activity of acid fluid and the migration of dissolved substances, which is of positive significance to the formation of dissolution pores. Distributary channel and subaqueous distributary channel sandbodies are the main carriers of medium and coarse-grained sandstone and should be the preferred target of deep oil and gas exploration.
