A model for the Lower Tertiary framework and sequence system tract of Jiyang subbasin was established with the high_resolution sequence stratigraphy. 建立了濟陽(yáng)坳陷下第三系高精度層序地層格架和層序體系域的構成模式。
In order to reveal the gas reservoirs distribution rule, the sequence stratigraphy and reservoirs overlap and distribution of Lower Shihezi Formation were studied. 為了查明氣藏分布規律，研究了下石盒子組層序地層格架及其儲集砂體的疊置與分布規律。
