植物胶泥浆在复杂地层钻进取心中的应用研究

Application Study on Plant Glue Drilling Fluid for Core Drilling in Complex Formations

摘要:

在室内实验的基础上，植物胶泥浆在苏州大阳山隧道工程勘察、常州金坛矿山资源勘查、句容铜山勘探中进行了试验应用研究。试验研究结果表明，植物胶泥浆在复杂地层的钻探施工中，在确保取心质量的前提下，可大幅提高钻进生产效率，降低施工成本。

Abstract:

Based on the laboratory experiments, the paper introduces the experimental studies on plant glue drilling fluid in Dayangshang tunnel engineering investigation in Suzhou, Jintan mineral resources exploration in Changzhou and Tongshan coalbed exploration in Jurong. The results show that in complex formation drilling, the drilling efficiency can be greatly improved by using plant glue drilling fluid with good core quality.
