Paleo-formation Pressure in Storage Layer and its Influence on Hydrocarbon Migration in Dongying Depression

摘要：

The study of storage layer paleo-pressure in hydrocarbon accumulation period reveals the oil migration direction in Dongying depression. By using of stratum back-stripping method and porosity evolutionary function, the paleo-depth and paleoporosity of storage layer during Ed, Ng and Nm periods are restored firstly, then the paleoformation pressure is further recoveredby the help of Fillippone formula and time-average equation. The study shows that pressure coefficient is increasing gradually over the 3 periods and overpressure distribution is due to the opening faults. Relations between paleo-pressure and hydrocarbon migration have been analyzed to deduce oil migration direction in storage layer.
