The interaction of sedimentary water and infiltration water results in a pressure equilibrium zone, where hydrocarbons accumulate.
The results show that the infiltration water temperature has strong influence on infiltration into frozen soil, the infiltration capacity enhanced with the water temperature increasing.
The results indicated that desalt depth increased exponentially with cumulative infiltration water volume, decreased with water salinity and initial water content.
Oil and gas reservoirs in Biyang depression distribute in circularity in the pressure equilibrium zone on the frontal surface between sedimentary water and infiltration water.
