Gas hydrate usually occurs with deepwater hydrocarbon together in the deepwater basin of the northern South China Sea.Gas hydrate is not only a giant potential resource,but also an important factor of geohazard for deepwater oil development.It could have great economic benefit if deepwater oil and gas hydrate could be developed together.However,it is unclear for the distribution of the gas hydrate and deepwater hydrocarbon.Based on the high resolution seismic data of Baiyun Sag in the north of South China Sea,various hydrocarbon leakage structures were discovered,such as gas chimneys,coarse submarine fans,active faults,submarine slides and polygonal faults,etc.Finally,the reservoir-forming model of gas hydrate was proposed,and the distribution law of gas hydrate coexisting with free gas and deepwater hydrocarbon was indicated.
