| 摘 要： | 通过对中扬子区层序样式基本类型和特点的研究 ,认为该区存在 T型、H型和 TH型三种基本样式 ,它们的层序特点不同 ,沉积特征有异 ,成因模式有别。从沉积学角度探讨了成藏条件 ,认为层序样式对成藏条件具有重要影响。在克拉通沉积区 ,烃源岩主要位于 H型层序样式的 TST;储集岩主要与 H型层序样式的 HST有关 ;良好盖层主要与 H型层序样式的 TST有关 |

| Abstract: | The concept of sequence style is suggested, and the basic catalogues and characteristics of sequence style in the Mid Yangtze area are studied in this paper. The result shows that there are three styles called T, H, and TH. They have marked different characters of sequence and deposition, and mechanics of formation. The conditions of reservoir formation are discussed from the angle of sedimentology , and an important relationship between them have been recognized. In craton sedimentary areas, the transgressire system tracts (TST) of H style is mainly related to source rocks and nice cap rocks , and the highstand system tracts (HST) of T style is generally related to reservoirs. |
| Keywords: | sequence stratigraphy sequence style marine deposit oil/gas exploration Yangtze plate |
