快速查清海域水合物资源及引领开采技术的创新思维

Innovative thought on quickly and clearly surveying the gas hydrate resource and leading production technology

摘要:

本文针对海域天然气水合物的赋存特性及勘探开发现状，结合陆域固体矿产勘探中的反循环钻探技术优点，提出了将反循环钻探技术应用于海域天然气水合物资源调查评价的创新思维。文中分析了反循环连续取心技术用于海域水合物资源调查评价的可行性、施工过程中可能遇到的技术问题及相应的技术措施、经济与社会效益等技术问题。提出的观点可为快速查清海域水合物资源、为人类提供新的接替能源及绿色海洋钻探施工发挥积极的引领和推动作用。同时还提出了开采过程中防砂除砂以提高开采产量的技术措施。

Abstract:

In response to the occurring characteristics and current status of exploration and production of gas hydrate， this paper presents an innovative thought with combination of the hydraulic reverse circulation drilling used in land mineral prospecting which will be used for oceanic gas hydrate survey and resource appraising. The feasibility， some technical problems and measures， economic and social efficiencies and so on of the hydraulic reverse circulation drilling are discussed. The thought would play an active role in quickly assessing the gas hydrate resource and providing the replacing resource and leading production for mankind. At the same time， the technical measures for increasing production of the gas hydrate and preventing and removing the sand are presented in the paper.
