By reviewing the exploration history of Jurassic hydrocarbon reservoir of Malang depression in Santanghu basin,this paper summarizes systematically the geological cognition.

Lithofacies paleogeography and petroleum geology of the Silurian in Yangtze area;

The Problems of the Standard in Petroleum Geology and Exploitation;

Through field investigation of petroleum geology and sample analysis, as well as combinating the new information attained in recent years, the petroleum geological conditions of Jurassic and Cretaceous strata in Jianchang—Kazuo basin were recognized and evaluated.

By observation of the outcropping profile, description and analysis of the drill samples, interpretation and multidisciplinary analysis of seismic data and well logging data, and by doing comprehensive research for the characterization of oil geology, the basin structural evolution, the faulted zone, and the depositional history, the further exploration strategy will get enough foundation.
