回顾、总结南方海相碳酸盐岩区40余年的勘探历程、失利原因，借鉴四川盆地勘探经验教训，并结合该区具体构造演化过程，提出评价、优选下步勘探目标的途径和具体操作方法。研究表明区域盖层、古隆起、后期保存条件匹配良好的构造单元是下步有利的勘探目标。 After reviewing and summarizing the exploration process and causes of defeat for more than 40 years in the marine carbonate area in the South China, the experience and lessons of exploration in Sichuan Basin are summarized. Based on the specific tectonic evolution of the area, the evaluation and optimization of the exploration targets and the specific operation methods . The research shows that the tectonic units with well-matched tectonic units in the regional caprock, paleohigh and post-preservation conditions are favorable targets for next exploration.
