摘　　要：本文阐述了无固相微泡沫泥浆和低固相微泡沫泥浆在炉坪矿区岩芯钻探中实际应用的配比、性能参数和相关泥浆材料的性能、功效,以及微泡沫泥浆的流变特征;并且简要论述了影响泡沫泥浆性能的主要因素,定量分析了微泡沫泥浆液柱压力低和弱冲蚀性的原因,特别介绍泡沫堵漏原理、泡沫泥浆成膜原理和润滑原理,实验证明微泡沫泥浆在岩芯钻探中能有效的节约生产用水、提高岩芯采取率、增加台月效率。In this paper, the real preparation, capacity parameter of solid-free micro-foam mud and low solid micro-foam mud in the core drilling of Luping orefield, the capacity, efficiency of related mud material and the rheological property of micro-foam mud are interpreted ; and the main factor affecting the property of foam mud is interpreted in short, the origin of the low pressure and weak erosion of micro-foam mud liquid column are analyzed quantitatively and the principle of leak resistance, film-forming and lubricating of are especially introduced. The practice has confirmed the micro-foam mud can effectively save water, increase core extraction and drilling efficiency.
