地层压力分隔化是由于沉积物在成岩演化过程中受各种因素,如沉积速率、沉积物类型以及成岩作用的影响,使地层中的流体压力梯度呈现出随深度变化不连续的一种现象。根据地层压力梯度的变化可以划分地层的压力结构。压力分隔化在一定程度上控制着油气在地层中的聚集与分布。本文通过对塔里木盆地中央隆起带油气藏实例分析来说明地层压力结构对油气分布的控制作用。
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.
