Title: Reservoir Characteristics Of Member 3 of Hetaoyuan Formation In the Southern Steep Slope of Biyang Depression
Abstract: Based on the southern steep slope in Biyang Sag of Nanxiang Basin,logging data,casting sections,geochemical and granularity material analysis are studied in detail,the southern steep slope in Biyang Depression with three clastic rock Hetaoyuan group of reservoir characteristics.The southern steep slope in Biyang Depression with walnut garden for a group of three sections fan Angle chau depositional systems,mainly sandbody in fan delta front of underwater distributary channel sand dam,estuary,the front seats shape,sublacustrine fan sandbody sedimentary microfacies,etc.The lithologic reservoir for lithic sandstone,feldspar sandstone reservoir space debris,with primary porosity and pore mainly connectivity,porosity average for 10%~20%,permeability average 10-3 for 1000m2,belong to holes through high permeability reservoirs.The causes of fan delta front slump sublacustrine sedimentary sand body has better properties,and the shallow lake around half deep lacustrine dark hydrocarbon source rocks,and is surrounded by the group of the most advantageous walnut reservoir sand.
