最近几年,对包括东引岛盆地、南彭佳屿盆地、北彭佳屿盆地、台湾盆地在内的近海北台湾盆地的盆地分析、地震地层、构造演化和烃类远景进行了多次研究.北台西盆地的盆地演化和构造特征的研究由纪等(1993)和黄等(1993)进行的.目的旨在了解北台西盆地与其它近海北台湾盆地之间的关系.我们的研究集中在观音隆起及其附近盆地区域的构造地质和石油系统方面.研究区位于台湾西北近海,并已示于图1.主要构造单元为南彭佳屿盆地、观音隆起、观音次盆地和相对的台湾-肉道构造带、东引岛盆地、南日岛盆地和北台西盆地.为便于解释起见,我们将位于南彭佳屿盆地和北台西盆地之间的观音隆起东南延伸部的凹陷暂时称作
In recent years, several studies have been conducted on the basin analysis, seismic stratigraphy, tectonic evolution and hydrocarbon prospects of the offshore North Taiwan Basin, including the Dongjintao Basin, the Nanpangu Island Basin, the North Pengjiayu Basin and the Taiwan Basin The study of basin evolution and tectonic features in the North Taixi Basin was conducted by Ji et al. (1993) and Huang et al. (1993) in order to understand the relationship between the Beitaihe basin and other offshore North Taiwan basins. Our research focuses on Guanyin uplift and its tectonic and petroleum systems in the vicinity of the basin, which is located in the offshore Northwest of Taiwan and is shown in Figure 1. The main tectonic units are the Nam Peng Jiayu Basin, the Guanyin Uplift, the Guanyin Sub-basin and the Taiwanese- Meiyindao tectonic belt, Dongyin island basin, Nanri island basin and Beitaixi basin For the sake of explanation, we will temporarily refer to the depression of the southeastern extension of Guanyin uplift located between the Nanpenjiayu Basin and the Beitaixi basin
