Huizhou is an area with the highest exploration maturity in Pearl River Mouth Basin

wherein the Zhujiang Formation is the primary oil-producing layer and has the potential of finding stratigraphic-lithologic traps.Through analyses on the factors controlling sandbody distribution of the Zhujiang Formation in Huizhou area

this paper concludes that various factors including palaeogeomorphology

sequence stratigraphy

delta-dominated sedimentary facies distribution and hydrodynamics in transitional zone during basin transformation and subsequent tectonic movements all have important influences on the formation and distribution of sandstones.Sedimentary facies determines the macroscopic distribution of sandbodies

and sequence structure influences the lateral and vertical sandbody development and sandbody stacking patterns in different system tracts.Sedimentary facies and sequence structure are the two main controlling factors.Based on the study of the controlling factors and the discovered lithologic hydrocarbon reservoirs

this paper establishes development models of stratigraphic-lithologic traps of Zhujiang Formation in Huizhou area

and analyzes the favorable area and types of stratigraphic-lithologic traps.We believe that the lithologic pinchout traps around sedimentary slope-break and/or within transgressive system tracts are the best ones for hydrocarbon accumulation.
