PRESSURE STRUCTURE AND PETROLEUM DISTRIBUTION IN TAZHONG AREA

Pressure separation is usually controlled by the following factors, such as subsidence rate, sediment types and diagenesis during the diagenetic evolution, as a result the pressure gradient is uncontinuous. According to the variation of gradient pressure structure can be divided. Pressure separation controlled the petroleum accumulation and distribution to a certain degree. This paper illustrated the viewpoint by example of petroleum reservoirs in Tazhong uplift, Tarim Basin.
