南海北部西区新生界天然热释光强度为０．２２×１０２～１７×１０２（平均２×１０２），并且随着地层时代变新而呈递增趋势。南海北部西区特别是新生代以来，至少发生过如下几次重要的构造热事件：前新生代（可能是多次）、老第三纪末─新第三纪初和新第三纪晚期，从而造就了研究区独特的新生代沉积建造和构造热场格局及相关的油气藏类型。南海北部西区油气田的形成与定位，主要是老第三纪末─新第三纪初构造热事件作用的结果。
The natural thermoluminescence intensity of the Cenozoic in the western part of the northern South China Sea is 0.22 × 102-17 × 102 (average 2 × 102), and shows an increasing trend as the stratigraphic age changes. Since the western part of the South China Sea, especially the Cenozoic, at least the following important tectonic thermal events have taken place: the Pre-Cenozoic (possibly multiple times), the end of the Neo-Tertiary-Late Neogene and the Neogene, and thus This has resulted in the unique Cenozoic sedimentary formation and tectonic thermal field patterns and the related types of reservoirs in the study area. The formation and orientation of the oil and gas fields in the western part of the South China Sea are mainly the result of tectonic thermal events from the end of the Ol-Tertiary to the beginning of the Neogene.
