| 摘 要： | 通过对我国南方广西宁明，上思，海渊３个盆地的研究，分析了残留盆地的基本类型，判别标志及其石油地质意义，指出：残留盆地是原型沉积盆地被后期构造运动强烈改造而成，主要有挤压逆冲型和垂向抬升型两种类型，空间上具有盆地面积大为缩小，地层遭受明显剥蚀，原型盆地面貌不复存在，生油岩成熟度高等特点，油气地质条件总体不如同沉积盆地有利，但仍具有小规模，埋藏浅，易开采油气藏的可能。

| Abstract: | The basic types and distinguishing criteria of the relict basin and their significance in petroleum geology are analyzed through the study of three basins Ningming, Shangsi and Haiyuan of Guangxi Zhuang Autonomous Region. It is indicated that the relict basin was formed through the intensive transformation of the prototype sedimentary basin by the later tectogenesis. There are mainly two types: compressive thrust and vertical uplift. The relict basin is characterized by its much smaller area than prototype basin, noticable denudation, considerable changes of proto-compressive basin appearance and high maturity of oil-generating strata. In oil-gas geological condition the relict basin is generally not so favorable as the contemporaneous sedimentary basin does, but it is characterized by small scale, shallow occurrence and easy mining of oil-gas pool. |
