Abstract

Abstract:

According to its 13 lithologic microfacies,14 lithologic facies,7 sedimentary microfacies and the characteristics of 9 mudstone layers formed in lake transgression,Chang 6 member in Jing'an Oilfield could be divided into one parasequence series(PSS),3 parasequences (PS₁,PS₂,PS₃).In PS₁,the sedimentary microfacies varies from shallow lake or prodeltaic facies-frontal deltaic facies to subaqueous distributary channel facies,or from interbranch channel facies to deltaic plain distributary channel facies in ascendind order,reflecting lake transgression regression process.In PS₂,the microfacies varies from prodeltaic deltaic front facies to distal bar-river mouth bar facies and then subaqueous distributary channel facies,reflecting the parasequence development process of water getting shallower and shallower.ndistributarychannelfaciesina

Key words: Jing'an Oilfeld, Chang 6 member, lithologic microfacies, lithofacies, single well facies, sequence stratigraphy
