摘要
概述了水力反循环(HRC—Hydraulic Reverse Circulation)连续取心钻探技术首次在我国海南砂矿勘查取心(样)钻探施工过程及取得的效果;总结了海上砂矿取心(样)钻探施工的经验。该技术的成功应用,为国内外开展海洋区域地质、海洋环境地质、海洋工程地质调查等钻探取心(样)施工提供了一种全新、高效实用的技术方法。
The paper outlines and summarizes the initial application process and effect of the HRC drilling and the experience for placer mineral prospecting in Hainan of China. The successful application of HRC supplies a new and high efficient technology for coring （sampling） drilling in marine geological survey in China and foreign countries.
