前陆盆地构造演化复杂,不同时期的沉积充填模式和沉积相受多种因素的影响。以南美哥伦比亚亚里次盆地为例,通过分析区域构造演化历史,认为盆地的沉积模式受盆地构造发育阶段、盆山耦合关系、海陆转换、造山带位置和气候等条件的影响。在此基础上研究了区内主力储层的沉积特征和形成条件,从而为确定储层发育特征和油气勘探开发提供有力支持。
The foreland basin tectonic evolution is complicated, the sedimentary filling patterns and sedimentation in different periods are affected by many factors. Taking the Aries basin in South America and Colombia as an example, we analyze the evolution of the regional tectonic evolution and think that the sedimentary model in the basin is affected by the tectonic development stage, basin-mountain coupling, land-sea conversion, the orogenic belt location and climate conditions. Based on this study, the sedimentary characteristics and formation conditions of the main reservoirs in the area are studied, so as to provide strong support for the determination of reservoir development characteristics and oil and gas exploration and development.
