Characteristics of Fan Delta Microfacies and Its Hydrocarbon Distribution in Anpeng Field

Abstract

Abstract: The microfacies feature of tight sandstone reservoir in fan delta of Anpeng oilfeidl in Biyang 8ag is studied on the basis of sedimentology, reservoir geology, logging geology and core data, combined with the recognition of sedimentary facies signs like sediment granularity. The fan delta can be subdivided into two subfacies and three microfacie8. The characteristics of deposits, petrophysical property and distribution of these microfacies are elaborated. The relationship between the microfacies and oil-gas distribution is analyzed. lt is suggested that the mid-distal subaqueous distributary channel and channel mouth bar are the favorable microfacies for oil-gas accumulation.

Key words: Biyang sag, Anpeng field, fan delta, oil and gas
