(1)Based on structural characteristics of J 1-2 basins in northwestern China, these can be divided into four types: extensional faulted depression with low angle boundary fault;extensional faulted depression with high angle boundary fault; intracratonic basin and craton marginal basin.

Hence,the distribution of oil and gas is controlled by the paleo-uplift in the small cratonic basins and thrust fold belts in the foreland basins in the Tarim basin,which resulted in the formation of oil and gas accumulation of voluminous litho-strata and anticlase,respectivelg.

Gas preservation conditions required in forming large-medium gas fields with high efficiency in Cratonic basin of China;

The Qamdo-Riwoqe Triassic cratonic basin in eastern Xizang:sequence stratigraphy and correlation;

Afterwards,cratonic basins were superimposed by foreland basins,following supercontinent amalgamation.

Oil and gas accumulation in craton basins of China and exploration strategy;

Hydrocarbon is enriched with obviously uneven distribution in craton basin.

As an example in the Mid-Yangtze area, the basic catalogues and characteristics of sequence style in craton basin have been studied, the mainly key factors for sequence style forming have been discussed, and the sequence style distribution model called as F,S,R and P has been improved.
