LF35-1-1井钻探证实,潮汕坳陷确实是一个中生代残留坳陷,坳陷中充填有白垩纪陆相沉积及中—晚侏罗世海相沉积,其中中—晚侏罗世海相沉积具有良好的石油地质条件。LF35-1构造位于东沙隆起岩浆活动活跃带,因此LF35-1-1井所揭示的烃源岩热演化特征不能代表整个潮汕坳陷的热演化史;推测远离东沙隆起岩浆活动活跃带的中南部地区是潮汕坳陷中生界油气勘探的有利方向。
Drilling of Well LF35-1-1 confirmed that the Chaoshan depression was indeed a Mesozoic remnant depression filled with Cretaceous terrestrial sediments and mid-late Jurassic marine sediments. The middle-late Jurassic marine sediments had good Petroleum geological conditions. The LF35-1 tectonic zone is located in the active zone of the Dongsha uplift. Therefore, the thermal evolution characteristics of the source rocks revealed by the LF35-1-1 well can not represent the thermal evolution history of the whole Chaoshan depression. It is presumed that the southern part of the active zone far away from the Dongsha uplift The area is a favorable direction for Mesozoic hydrocarbon exploration in the Chaoshan depression.
