Optimization and test of hydraulic DTH hammers used in hot dry rock drilling
-
摘要: 我国目前能源结构对化石燃料依赖度过高,在全球能源转型的大环境下,作为一种新型清洁能源,干热岩具有储量巨大、资源丰富、分布广泛等优势。针对干热岩勘探开发中高温硬岩钻进的技术难点,对YZX178型液动潜孔锤进行了结构优化,并在某干热岩井中进行了试验应用。试验结果证实了YZX178型液动潜孔锤用于干热岩等坚硬地层进行冲击回转钻进的可行性和高效性,获得了与螺杆钻具接近的机械钻速,且具有节能环保、安全性高、维护方便、节约成本、高温适应性强等优势,但仍需进一步解决其工作寿命与牙轮钻头相匹配的问题。Abstract: At present, China depends highly on fossil fuels in the perspective of the energy structure. In the context of global energy transformation, as a new type of clean energy, hot dry rock has the advantages of huge reserves, rich resources and wide distribution. In view of the technical difficulties in drilling of high temperature hard rock in hot dry energy exploration and development, YZX178 hydraulic DTH hammer was optimized in terms of its structure and applied in hot dry rock wells. The results show that YZX178 hammer is feasible and efficient for drilling hard formation such as hot dry rock. It has the advantages of energy saving, environmental protection, high safety, convenient maintenance, cost saving and high temperature adaptability. However, more work needs to be done to solve the problem of matching the working life of the hammer and the roller bit.
