摘要
为探查张掖市沙漠体育公园地热资源,在公园内施工了一口地热勘探井。该井设计井深2150m,完钻井深2174.03m。本文从该井钻遇地层情况、井身结构、设备选用、钻探施工技术和抽水试验等方面介绍了该井钻完井过程,总结了钻井工作取得的相关成果。该井揭露了新近系白杨河组和白垩系热储层水文地质参数,为园区内地热水资源评价和开采利用提供了可靠地质依据。
In order to explore the geothermal resources in Zhangye Desert Sports Park,a geothermal exploration well was constructed in the park.The design depth of the well is 2150m,and the drilling depth is 2174.03m.In this paper,the drilling and completion process of the well is introduced from the aspects of the drilling situation,well structure,equipment selection,drilling construction technology and pumping test,etc.,and the relevant achievements of the drilling work are summarized.The well reveals the hydrogeological parameters of Neogene Baiyanghe Formation and Cretaceous thermal reservoir,and provides a reliable geological basis for the evaluation and exploitation of inland hot water resources in the park.
