| 摘 要： | 马都拉海峡盆地属特提斯构造域东段，晚渐新世至早中新世裂后稳定沉降时期沉积大面积碳酸盐岩，是区内最重要的油气储层之一.为探讨该时期盆地演化模式，依据马都拉海峡盆地钻遇库炯组的钻井数据和岩心照片以及约120 km长的二维地震数据，通过井沉积相和地震相分析，将盆地地震相划分为6种类型，识别出库炯组珊瑚生物礁以区内F6反转断裂带为界具有明显的南北分区特征.依据珊瑚生物礁生长发育所需特殊环境，认为马都拉海峡盆地裂后沉降期被一系列EW向正断层分为中南部浅海陆架开阔台地区和北部相对深水区，呈现出"南高北低"的古地理特征.

Characteristics and Paleogeographic Indications of the Late Oligocene to Early Miocene Coral Reefs in the Madura Strait Basin,Indonesia |

| Abstract: | The Madura Strait basin belongs to the eastern part of the Tethys tectonic domain. During the Late Oligocene to Early Miocene post-rift subsidence stage, a large area of carbonate rock was deposited, which is one of the most important oil and gas reservoirs in the study area. It analyzed the sedimentary facies and seismic facies based on the drilling with core photos and 2D seismic profiles with a total length of about 120 km of the Kujung in the Madura Strait basin to explore the basin evolution model during this stage. The basin seismic facies is divided into 6 types, and it is found that the coral reefs of the Kujung have obvious north-south regional features with F6 reverse fault as the boundary. According to the special environment required for the growth and development of coral reefs, it consider that the post-rift subsidence stage of the Madura Strait basin is divided into two parts:the southern shallow marine open platform and the northern deeper marine by a series of EW normal faults. It shows the geomorphological features of "the south higher than the north". |
