The TSM one-dimensional basin model system assemblage is one of the results of program“quantitative research of hydrocarbon generation and accumulation in the Dongying Sag”of the Technologic Department of SINOPEC.

The parameter sensitivity and risk analysis for basin modeling;

Based on effective source rock assessment,this paper analyzes the characters of effective source rock in inter-salt non-sandstone of the Qianjiang depression,the amount of hydrocarbon generation and the oil & gas resource potential by using the methods of basin modeling,and the best plays for prospecting are evaluated.

These issues have been considered using geological data and basin modelling.

Based on the stastical method study of hydrocarbon generation threshold done by former researchers, this paper gives an improved method and applies it to basin modelling of an oil field in Liaohe basin.

Based on physical and chemical features analysis of subsurface water in west slope of Songliao Basin,subsurface water evolution history in the region of interest is retrieved with Basin2 basin simulation program, and relationship between formation hydrodynamic field evolution and hydrocarbon accumulation is discussed.

By the basin simulation system-ProBases, the tectonic, thermal, hydrocarbon generation, and stratigraphy pressure evolution history in Qikou sag are synthesized and analyzed , indicating that they are well matched each other for hydrocarbon migrating and accumulating.
