Based on the practices in Qintong depression of Subei

Changling depression in southern Songliao basin and Xihu depression in East China Sea

constrained modelling through geological analysis of basins'

prototypes and their juxtaposition and superimposition relations

and combining geological thinking in images with mathematical logic thinking

"TSM"basin system modelling of geologic processes and oil & gas response relations are carried out by using combination of multiple modules and multiple programs. Now

modelling of rift's 2-D subsidence process has been realized in the domain of stacking geology of fault-subsidence prototype basins

which reveal the superimposition of various prototypes of basins would change the geological processes

control the generation and distribution of oil and gas

indicate migration path of oil and gas

and can even predict zones of oil and gas accumulation. Tainan oilfield has thus been discovered in Subei

and a considerable amount of commercial production has been acquired in Darhan reversed structure in southern Songliao basin. Although"TSM"basin system modelling

with essential prediction functions

has been preliminarily applied in practice to serve decision-making in petroleum exploration

it is still in an initial stage with large amount of R&D work to be performed

such as simulation systems for various prototypes of basins

including compressing and squeezing foredeep basin

strike-slip and extensional basin and intracontinental depression basin

as well as simulation of superimposition of various prototypes of basins. Nevertheless

"TSM"modellng has built a bridge leading from known to unknown

and it will become one of the innovative technology chains in our petroleum exploration.
