摘要

Abstract

The Chaoshan depression

a Mesozoic basin in the Dongsha sea area

northern South China Sea

is characterized by well-preserved Mesozoic strata

being good conditions for oil-gas preservation

promising good prospects for oil-gas exploration. However

breakthrough in oil-gas exploration in the Mesozoic strata has not been achieved due to less seismic surveys. New long-offset seismic data were processed that acquired with dense grid with single source and single cable. In addition

the data were processed with 3D imaging method and finer processing was performed to highlight the target strata. Combining the new imaging result and other geological information

we conducted integrated interpretation and proposed an exploratory well A-1-1 for potential hydrocarbon. The result provides a reliable basis for achieving breakthroughs in oil and gas exploration in the Mesozoic strata in the northern South China Sea.
