Discussion on the exploration key technology on the stratigraphic overlap oil reservoirs in Chengdong Arch;

Rolling exploration and development of miniature trap reservoir at gentle slope belt of Chengdong arch.;

servoir characteristic and prediction technique of lithological hydrocarbon deposit of Guantao formation in the northern slope of Chengdong arch.;

After deep study of Eg channel sandstone reservoir in northern slope of Chengdong arch in recent years, a set of more mature description technique of Neogene channel sand reservoir and oil-bearing identification technique of sand body has been formed on the basis of comprehensive geologic analysis and having the backing of geophysical technology.

Petroleum geochemistry characteristics and reservoir-forming system division of Kendong arch;

Some aspects on Kendong Arch are analyzed, such as the characters of oil pool formation and occurrence rules, evolution.

Tectonic Characteristics and Hydrocarbon Accumulation of Kendong Uplift,Bohai Bay Basin;

Based on the vertical and areal analysis distribution of discovered reservoirs in Kendong uplift,the paper has discussed the relationship between Neogene hydrocarbon migration_accumulation and faults, indicating that these faults are the main passages of vertical hydrocarbon migration.

Kendong uplift is surrounded by hydrocarbon-generating sags and has a great resource potential.
