4000m地质岩心钻机在天津东丽区地热资源调查中的示范应用
Demonstration application of 4000m geological core drilling rig in geothermal resources investigation in Dongli district of Tianjin
【摘要】 为了验证XD-40型钻机的性能参数,结合天津市东丽区地热井工程进行了示范应用。在钻进过程中311mm口径钻深2258.83m,超过了钻机额定钻深能力,提升系统、回转系统、液压系统、交流变频控制系统、数据及仪表参数监控系统、数据储存系统、钻机底座及钻塔等主要技术性能得到验证,并对钻机总体布置、控制系统程序、实用性设计进优化完善。XD-40型钻机机械化程度高,可以满足深孔钻探工艺要求,并可在地热、浅层油气勘探等领域进行应用拓展。
【Abstract】 In order to verify the performance parameters of XD-40 drilling rig,demonstration application is carried out in combination with the geothermal well project in Dongli District of Tianjin.During the drilling process,the drilling depth reached 2258.83 mat 311mm diameter exceeding the rated drilling capacity of the drilling rig,which has proved the main technical performance of the lifting system,rotary system,hydraulic system,AC frequency conversion control system,data and instrument parameter monitoring system,data storage system,drilling rig base and drilling tower;meanwhile the overall layout,control system program and practical design of the drilling rig have been optimized and improved.XD-40 drilling rig is featured of a high degree of mechanization,meeting the requirements of deep hole drilling,and its application may be extended to geothermal,shallow oil and gas exploration and other fields.
