江汉盐湖盆地潜江组沉积控制因素与岩性油藏

Some Controlling Sedimentary Factors and Lithologic Oil Reservoirs in Qianjiang Formation of Jianghan Salt Lake Basin

潜江组储层是江汉盐湖盆地最重要的产油层系。潜江组沉积充填主要受到盆地的构造演化和古气候条件控制。为此,总结了四种不同的水动力强度控制条件下砂岩储层分布模式。潜江组不同类型岩性圈闭具有在不同地区成带分布的特点,为岩性油藏提供勘探依据。

Qianjiang Formation reservoir is the most important productive series in Jianghan Salt Lake Basin. The sedimentary fillings of Qianjiang Formation are mainly controlled by structural evolution and ancient climate conditions. This paper concludes four distributive modes of sandstone reservoirs which are controlled under different hydrodynamie intensity conditions, The different type of lithologie traps of Qianjiang Formation distributes zonally in different areas,which will provide a basis for lithologic oil rservoirs exploration.
