摘　　要：黄冈至大冶天然气管道穿越长江段拟采用定向钻法施工。为准确查明穿越段的地质情况,选择最佳穿越路径,提前制订了相应的施工方案和故障处理措施。通过采用传统小口径钻探,并结合声波、高密度电法、松散岩土层可视化探查技术、井下全息彩电探测和三维建模等一系列优质、先进的勘察技术方法,经综合分析,获取了详实的地质勘察资料,确保了工程的顺利、成功实施。详细介绍了勘察过程,其综合勘察技术及工程经验可供同类工程参考。The directional drilling method is to be used in the construction of gas pipeline from Huanggang to Daye crossing Yangtze River. In order to ascertain the geological condition of the crossing section, so as to select an optimal crossing route, we have worked out the construction scheme and treatment measures of accident in advance. By using traditional small caliber drill- ing and together with a series of advanced survey technologies such as sonic wave, high density resistivity method, visual detect for loose soil layer, down - hole holographic color TV Technology and 3 - D modeling etc. , the geological condition of the cross- ing stratum was made clear accurately, which ensured the smooth and successful construction of the works. This paper gives a de- tail introduction to the survey process and the comprehensive technologies, which can he referred by the similar works.
