The reservoirs of the third member of Guantao formation
in Panhe fault block are mainly braided fluvial sediment, this
article discusses fluvial sedimentary p roperty in lithology,
sedimentary structure, sandbody shape and heterogeneity, its
sedimentary structures are mainly beddings and the structure
of stratified p lane and the shapes of sandbodies are mainly
boxer-like shape and bell shape. so, the author considers that
each formation develop s mainly lag deposit and mid-channel
barmicrofacies according to its sedimentary microfacies and
p lane distributions. Reservoir p roperty and sedimentary
microfacies have better corresponding correlation: the main-
body of mid-channel bars have the p roperty of bigger
thickness, better physical p roperty and higher saturation than
the fringe of mid-channel bar and worse is discussed
riverway, meanwhile, the oil-bearing of reservoir is controlled
by structure and diagenesis.
