Abstract:
In continental dustpan-shaped depression,fan deltas mainly develop in fault-slope beltwhich is in steep shore region along the direction of short-axis in the depression.By means ofsedimentology,well-logging geology and seismic stratigraphy of Shahejie formation in Leng-dong-Leijia region in western part of Liaohe depression,two types of fan deltas are recognized,i.e,steep slope-pattern fan delta and gentle slope-pattern fan delta,and their sedi-mentary and reservoir features are discussed.The result provides important geological theo-retical basis for hvdrocarbon exploration and reservoir description of the fault slope of continertal dustpan-shaped deprsssion.
