Abstract

A set of typical sedimentation of sublacustrine fans in lower Cretaceous in Wuliyasitai sag of Erlian basin is composed of feeder channel, inner fan, middle fan, and outer fan. The main micro-facies include feeder channel and main channel in inner fan, furrow dam and braided channel in middle fan, inter-channel and sheet turbidite sand in outer fan. Although a single sub-lacustrine fan is not large in scale, the sedimentation is characterized as multi-stage development, group distribution, vertical superposition, and superimposed horizontal lace. Thus, the depositional scale is large. The big open ended space and continuous supply of deposits are two key factors for f-ming the thick sub-lacustrine fan. Meanwhile, the place of downthrown block of growth fault or the slope-break zones is the favorable area for the sub-lacustrine fan development. The conglomerate body in sub-lacustrine fan is close to hydrocarbon-generated sag and prone to lithologic trap formation and hydrocarbon accumulation; thus it is important for oil and gas exploration.
