| 摘 要： | 泥炭是一种具有多种用途的宝贵自然资源，泥炭中的有机碳储量是研究全球碳库变化及碳循环过程的重要参数。由于泥炭多分布于沼泽中，且泥炭松软含水量大的特性，对于泥炭深度的调查、获取用于测试泥炭原状样品的质量不高，导致泥炭碳储量评价仍存在不确定性和偏差。笔者等在典型泥炭形成地若尔盖沼泽湿地地区，开展了浅钻泥炭调查取样工作，通过在泥炭斑块边缘及中心两种不同沼泽湿地地层开展的试验，验证了轻便钻机在难进入的沼泽湿地的适应性，配套的振动冲击工艺可高质量的获得无扰动的泥炭样品，同时查明了泥炭层的厚度。通过试验初步探索了采用轻便钻机配套振动冲击钻进工艺进行泥炭调查取样的有效性。浅层取样钻探作为泥炭调查取样的一种直接有效的技术手段，可以有效地提高泥炭调查效率和精度，为准确评价泥炭储量数据提供可靠的钻探技术服务支撑。

| Abstract: | Peat is a valuable natural resource with multi- purpose. The storage of organic carbon in peat is an important parameter to study the change of global carbon pool and carbon cycle. Due to the particularity of peat distribution in bogs and soft peat water content, the quality of peat depth survey and original peat samples obtained for testing is not high, leading to uncertainty and deviation in the evaluation of peat carbon storage. Through the sampling test of shallow drilling peat investigation in the typical peat formation area of the zoige swamp wetland, the method of undisturbed sampling by vibration shock of portable drilling rig was explored. The adaptability of portable drilling rig in difficult to access swamp wetland has been verified by experiments carried out in two different bog and wetland strata at the edge and center of peat patch. The matching vibration shock process can obtain high- quality undisturbed peat samples and depth information of peat. The effectiveness of peat survey and sampling using vibration and impact drilling technology with portable drilling rig was preliminarily explored through experiments. Shallow sampling drilling, as a direct and effective technical means of peat survey, can effectively improve the efficiency and accuracy of peat survey and provide reliable drilling technical service support for the preparation and evaluation of peat reserve data. |
