1月14日,南海天然气水合物钻探工程在广州通过验收。验收组认为,本次钻探在圆满完成规定的各项外业任务基础上,实现了天然气水合物开发利用领域的又一次重大突破。至此,我国正式形成海域天然气水合物从调查评价到钻探阶段的方法技术体系,为大面积开展海域天然气水合物资源调查评价和勘查,奠定了坚实的技术基础。据悉,这套方法技术体系目前处于国际先进水平,主要由调查评价和勘查两部分组成。调查评价方法技术方面,形成了成熟的水合物调查技术,围绕水合物成矿远景区,开展了与水合物赋存相关的地貌、沉积矿物、地球化学及地震调
January 14, South China Sea gas hydrate drilling project in Guangzhou passed the acceptance. Acceptance group believes that this drilling in the successful completion of the provisions of the various tasks based on the field to achieve the development and utilization of natural gas hydrate another major breakthrough in the field. So far, China has formally established a method and technical system for the exploration and evaluation of natural gas hydrate in the sea from the survey to the drilling phase, laying a solid technical foundation for large-scale investigation, evaluation and exploration of natural gas hydrate resources in the sea. It is reported that this method of technology system is currently in the international advanced level, mainly by the investigation and evaluation and exploration of two parts. In terms of technical aspects of investigation and evaluation methods, a mature hydrometeorological survey technique has been developed. Geomorphology, sedimentary minerals, geochemistry and seismogenesis related to hydrate occurrence have been developed around the hydrate mineralization prospect area
