摘要
As the coupling of hydrodynamic fields in petroliferous basins,a geotemperature-geopressure system (Geo-TPS) directly controls the migration and accumulation of oil and gas.Studies showed that characteristics of the Geo-TPS in China differ greatly from one petroliferous basin to another.Based on the relationship of Geo-TPS slopes in shallow and deep formations,three types of Geo-TPS models were put forward: the high-pressure multiple Geo-TPS (HP-MGeo-TPS),the low-pressure multiple Geo-TPS (LP-MGeo-TPS) and the single Geo-TPS (S-Geo-TPS).
