摘要

摘要: 黄桥地区是下扬子有利含油气区，后期改造强烈、构造复杂，制约着该区的油气勘探工作。黄桥地区经历3期构造运动叠加，形成了大量的正断层、逆断层和褶皱，组合成多种构造样式。通过区域构造和三维地震剖面精细解释，结合其成因，主要分为挤压构造、伸展构造和反转构造3种构造样式。在此基础上，将黄桥三维区分为西北斜坡带、中部隆起带和东南低凹带3个构造区，指出中部隆起带构造稳定区是油气勘探的有利区。

Abstract: The Huangqiao area is a key exploration target for oil and gas in the Lower Yangtze region. However, due to strong later transformation and complex structure, the oil and gas exploration work is restricted in this area. The Huangqiao area experienced three stages of tectonic movement, forming a large number of normal faults, reverse faults and folds, resulting in various structural styles. Three types of structural styles were identified according to their causes, including compressive structures, extension structures and inversion structures, based on the regional tectonic analysis and the fine scale interpretation of 3D seismic profiles. There are three tectonic zones, including the northwest slope zone, the central uplift belt and the southeast low-lying zone. The central uplift belt, as a stable structure area, is favorable for hydrocarbon exploration.
