大陆架科学钻探南黄海陆架区首钻300 m选位研究

SITE SURVEY FOR THE FIRST 300 m CORING HOLE OF THE CHINA CONTINENTAL SCIENTIFIC DRILLING PROGRAM IN THE SOUTHERN YELLOW SEA (SYS)

  • 摘要: 大陆架科学钻探300 m首钻选址于南黄海陆架区,以钻穿第四纪地层为目标。针对钻孔施工要求及后续研究的需要,提出钻孔部署的原则。在分析南黄海陆架区地形地貌、水深、第四纪沉积物厚度、沉积历史及沉积演化特征的基础上,结合调查区多道地震、单道地震、浅地层剖面及钻孔等资料,敲定了井场调查合理区。同时,在调查区对限制钻探工作的地貌类型和地震相进行了分析,最终选定钻探位置。另外,还根据调查区单道地震的特征对首钻300 m钻孔的纵向地层及岩性特征进行了预测,为实施第四纪地层全取心钻探提供依据。近日,海上300.1 m钻探取心的成功实施,表明孔位选取和沉积地层预测的技术方法是行之有效的。

     

    Abstract: The first 300 m drilling hole of the Chinese Continental Scientific Drilling Program (CSDP), aiming at stratigraphic study of the Quaternary deposits on the Chinese continental shelf, is selected in the South Yellow Sea (SYS). Upon the technical requirements of the drilling, and the geological-geophysical conditions of the SYS, such as topography, water depth, thickness of Quaternary sediments, sedimentary evolutionary history, based on the data of multi-channel seismics, single-channel seismics, shallow seismic profiles and boreholes nearby, and after careful consideration of favorable and unfavorable conditions, a reasonable drilling site is finally selected. In addition, a litho-stratigraphic column was provided upon the integration of all the data mentioned above. The successful implementation of the coring suggests that the method of hole site selection and stratigraphic prediction is effective.
