基金项目:国家重点研发课题“碳酸盐岩热储层强化增产与利用综合评价技术”(编号:2019YFB1504104)
中文摘要:2011年山东省地矿局在山东省利津县实施了国内第一个干热岩调查评价项目,采用转盘回转钻进,但钻效低、能耗高。为提高在高温硬岩条件下的钻进效率、缩短钻井周期、降低生产成本,2015年在福建省漳州市实施的中国地质调查局东南沿海深部地热HDR-1干热岩科学钻探工程井(井深4000.86 m,孔底温度109 ℃)和2017年在青海省共和县完成的GR1干热岩科学勘探井(井深3705 m,孔底温度236 ℃),在施工中均探索使用了“转盘+螺杆钻具”复合钻进工艺,并在高温取心段首次测试应用了“转盘+涡轮钻具”复合取心钻进工艺,取得了良好的效果并就下一步研究方向提出了意见和建议,为螺杆钻具和涡轮钻具的深入研究提供了宝贵的高温施工经验,也将为我国干热岩科学钻探与深部地热资源勘探提供新的技术支撑。

Application of compound power drilling technology in hot dry rock drilling
Abstract:In 2011, Shandong Provincial Bureau of Geology and Mineral Resources implemented the first domestic hot dry rock survey and evaluation project in Lijin County, Shandong Province, where rotary drilling was adopted, but the drilling efficiency was low and energy consumption was high. To improve drilling efficiency, shortening drilling cycle, reduce production cost in hard rock drilling at high temperature, in both the southeast coast deep scientific drilling hot dry rock geothermal well HDR-1 of China Geological Survey (depth of 4000.86m, hole bottom temperature 109℃) implemented in Zhangzhou, Fujian Province in 2015, and the hot dry rock scientific exploration well GR1 (well depth of 3705m, hole bottom temperature 236 ℃) implemented in Qinghai province in 2017, the compound drilling technology of “rotary table and mud motor” was tried, and the “rotary+turbodrill” compound coring drilling technology was tested over the coring section for the first time at high temperature with good results obtained. Some comments and suggestions are put forward on the future research direction, which provides valuable experience on high-temperature drilling for the in-depth study of the PDM drill and turbodrill, and also provides new technical support for hot dry rock scientific drilling and deep geothermal resource exploration in China.
