| 摘 要： | 区域地质背景反映珠江口盆地惠州地区中新统具有形成地层岩性圈闭的条件。研究惠州地区地层岩性圈闭的形成条件、控制因素和分布规律,对于该区油气勘探持续发展有重要意义。建立了惠州地区中新统高精度的层序地层格架,在此基础上分析不同类型层序的构型特点,研究不同类型坡折带的形成机制、分布范围及对沉积体系的控制作用。层序地层边界和坡折带是控制本区地层岩性圈闭形成的重要因素。惠州地区存在3种具有勘探前景的地层岩性圈闭,选择HZ27-3低位体钻探获得成功。

| Abstract: | The regional geological background has indicated that Miocene stratigraphic and lithologic traps may be created in Huizhou area.Studies on creation conditions,controlling factors and distribution pattern of the stratigraphic and lithologic traps are very important to continuous oil and gas exploration in the area.Based on establishing Miocene sequence stratigraphy framework with high resolution in Huizhou area,the configuration is analyzed for various sequences,and the formation mechanism,distribution and control on sedimentary system are researched for various types of slope-break zone.The sequence boundaries and the slope-break zones are the important factors to control creation of stratigraphic and lithologic traps in the area.There are three types of stratigraphic and lithologic traps with exploration potential,and the HZ 27-3 lowstand system tract has been drilled successfully. |
