Knowing the tectonic background under which, basins formed helps determining their geomechanical natures (extensional, compressional and shear) in each developmental phase and full understanding of the sedimentologic character and geothermal evolution of the basin.
Based on geothermal parameters calculation, geothermal evolution of the sourth ofthe Beierhu depression in the Hailar basin is simulated by 1-D non-linear transient heat transfer-advection equation.
Time-Temperature-Index(TTI)is used in petroleum geology to estimate the location of oil generation window. However, previous method for computation of TTI neglects the thermal effects of compaction of sediments and discharge of porous fluids.
The geothermal history of strata or rocks has been qualitatively and semi-quantitatively in Shiwanshan basin and its neighbouring region, based on analyses of fission-track apparent age and modelling of confined track lengths distribution of apatite samples.
According to the determination of apatite fission track ages and length, the annealing characteristics of apatite fission track, geothermal evolution and prediction of petroleum source in studied area are discussed.
Using modern analysis methods,a great number of complex zeolite group minerals are identified in details,and their lateral and verical distribution summarized. The authors suggest that formation of the zeolites is mainly due to alteration and hydration of the volcanic materials,and also due to the burial and thermal histories.
Geothermal condition is one of the main controlling factor for hydrocarbon occurence and their evolution. This is the essential basis that geothermal studies can be used as a effective method to evaluate and forecast the oil-gas resources.
