江苏及邻区中生代含油气盆地的类型、沉积特征和地球动力学背景

TYPES, SEDIMENTARY CHARACTERISTICS AND GEODYNAMIC SETTINGS OF MESOZOIC OIL - GAS-BEARING BASINS IN JIANGSU PROVINCE AND ADJACENT AREAS

根据研究，江苏及邻区中生代含同气盆地按时序要依次划分为少相裂陷盆地（Ｔ１－Ｔ２＾１）、前陆盆地（Ｔ２＾２－Ｊ１＋２）、陆内走滑－－拉张盆地（Ｊ３－Ｋ１）、陆内抛陷盆地（Ｋ２Ｐ－２Ｃ）和陆内断陷盆地（Ｋ２１－Ｅ）五类。这些盆地随着时间和空间的变化，在沉积充填序列、沉积－构造演化、油气储集等方面均具有不同特征，反映了它们是在不同地球动力学背景下发生变化的结果。

According to the study, Mesozoic oil-gas-bearing basins in Jiangsu province and adjacent areas can be divided into five types in chronological order: marine facies extentional basin (T_1-T_2~1), foreland basin (T_2~2--J_(1+2), introcontinental strike-slip-pull-apart basin (J_3-K_1), introcontinental down-warped basin(K_(2p+2c) and introcontinental fault basin (K_(2t)-E). These basins obviously have different characteristics in sedimentary-filling sequences, sedimentary-structural evolution, oil-gas reservoir and so on showing changes in space and time, which reveal that these basins formed in the different geodynamic settings.
