Abstract: The oil and gas shows of Lufeng 7-9 buried hill in Lufeng 13 subsag transition zone of the Pearl River Mouth Basin show its great exploration potential. Based on the data of drilling，logging，borehole cores，thin sections and geochemistry，the hydrocarbon accumulation characteristics of Mesozoic Lufeng 7-9 buried hill in Lufeng 13 subsag transition zone of Pearl River Mouth Basin were studied. The results show that：（1）Two sets of high-quality source rocks are developed in Lufeng 13 subsag，namely，the upper Wenchang Formation and the fourth member of the lower Wenchang Formation，with the average TOC of 1.54% and 2.55%，respectively，and the organic matter is mainly typeⅡ1. Lufeng 7-9 buried hill is adjacent to high-quality source rocks，with the advantage of double source and wide window hydrocarbon supply.（2）Lufeng 7-9 buried hill trap was initially developed in the Mesozoic Cretaceous，finalized in the Paleogene，and the high point position was stable for a long time，which is conducive to the migration，accumulation and preservation of oil and gas.（3）Weathering zone and inner zone are vertically developed in Lufeng 7-9 buried hill. The brittle felsic minerals are conducive to the development of buried hill reservoirs. The paleogeomorphology controls the distribution of high-quality reservoirs in the weathering zone. The continuous activation of pre-existing faults is conducive to the development of reservoirs in inner zone.（4）The faults，unconformities and internal network fracture system constitute the main oil and gas migration channels of Lufeng 7-9 buried hill，and two hydrocarbon supply models of lateral sourcefault-unconformity and lateral source-fault-network fracture are developed.（5）Lufeng 7-9 buried hill is a late accumulation model with crude oil filling period of 0～13 Ma. The space-time coupling relationship between different accumulation elements is good. It is a late accumulation model of double-sag near-source and wide window hydrocarbon supply， fault-unconformity-network fracture combined transport.

Key words: weathering zone, inner zone, paleogeomorphology, buried hill reservoir, near-source accumulation, Mesozoic, Lufeng 7-9 buried hill, Lufeng 13 subsag, Pearl River Mouth Basin
