摘　　要：针对金刚石绳索取芯钻进要求 ,研究获得了几组甲酸盐无固相钻井液体系配方。对其性能进行测试分析以及对其环保特性进行了评价。结果表明 ,甲酸盐钻井液密度可调范围大 ,流变性和润滑性好 ,抗高温抗污染能力强 ,符合国际环保规范 。To meet the requirements in the diamond wireline drilling, the authors obtained the formulae of drilling fluids through experiments. By testing and analysing their various behaviors, and evaluating their performance regarding environmental protection, the authors drew a conclusion that formate drilling fluids have a large scope of density modulation and possess good rheological, lubricant, anti high temprature, and anti inorganic contamination behaviors. This kind of drilling fluids accords with the relevant international norms of environmental protection and is a new kind of drilling fluids which can be used in the diamond wireline drilling.
