The Structure Characteristics and Petroleum Exploration Potential of Deep-Water Basins in Northern South China Sea
Abstract: The deep-water oil and gas exploration is the main direction of today’s oil and gas exploration. Deep-water basins in northern South China Sea have the similar characteristics area of the world’s major deep-water petroleum-basin. Northern South China Seadeveloped a series of deep-water passive margin basins, these basins developed thick sedimentary strata of Mesozoic and Cenozoic. Exploration conformed that these basins had good petroleum conditions of many sets of Cenozoic source rocks, including lacustrine mudstone, paralic mudstone and marine mudstone. The types of trap are mainly the large structural and lithologic traps. Reservoirs are Tertiary deep-water-fan sands with high porosity and permeability. The main Petroleum type is oil. There are many faults, unconformities and large good connectivity sands developed in deep-water basins, thus a good oil and gas transporting system is constituted. According to the results of basin modeling, deep-water basins have two peaks of hydrocarbon generation. The period of fold and fault activity during late Miocene matched well with the peak of hydrocarbon generation and expulsion. Deep-water basins ofNorthern South China Seahave good potential for oil and gas exploration.
