Exploration of subtle pool: past and future.;

Distribution features and exploration method of subtle pool in Biyang sag.;

And there are multi-stage strong tectonic movements,which form many types of subtle pools,such as lithologic hydrocarbon reservoir,stratigraphic hydrocarbon reservoir,fractured hydrocarbon reservoir,composite pool and buried structural trap.

Exploration of subtle reservoirs in the northern shelf basins of South China Sea;
