Fluid Potential Distribution and Oil & Gas Accumulation in Tertiary of Western Qaidam Basin

With the development of oil and gas exploration industry, researchers and engineers have realized that the key element controlling the migration of underground oil and gas and other fluid is not the pressure of stratum, but the underground fluid potential. Therefore, it is very crucial to study the distribution rule of fluid potential in order to correctly determine the exploration target areas. This paper studies the fluid potential distribution in Tertiary of west Qaidam Basin, puts forward the model of underground oil and gas migration and predicts the areas for further exploration.
