Tectono-thermal event in west foreland basin of Ordos and its effects on oil-gas migration;

Main oil-gas migration pathways of S_(2-3) oil layer in western slope zone and their effect on oil-gas accumulation;

The surpressure distribution and oil-gas migration in the southern slope of Dongying Depression;

The ratios of Ts/(Ts + Tm),tricyclic terpane to 17α(H)-hopane and rearrangement sterane to regular sterane are chosen as oil migration parameters.

Based on the composition and concentration changes of nitrogen compounds in the study oil samples as well as the maturity indexes of saturated and aromatic biomarkers, this paper investigated the oil migration and injection direction of Caofeidian and nearby areas in the offshore part of the Bohai Bay Basin.

Based on detail investigation of the composition for the oils and their source rocks, pyrrolic nitrocompounds and fluid inclusions have been analyzed to trace the process of oil migration and accumulation in the Wangzhuang-Ninghai region.

Application of fluid inclusions in the study on hydrocarbon migration and accumulation and some problems worthy to be discussed;

Changing patterns of hydrocarbon migration pathway in a up-scaling percolation model;

New opinions on oil and gas generation and exploration in Jiuxi basin(Ⅲ)—Oil and gas migration, pool formation and exploration target.;

The main direction of oil and gas migration at 5 unconformable surfaces, including top boundaries of Jiamuhe Formation, Permian, Triassic, Xishanyao Formation and Jurassic in Luxi area of Junggar Basin, is confirmed by palaeo-chorography, evolutionary profile and geochemical data.
