5000米地质岩心钻机主绞车设计

Design of the drawwork of 5000m geological core drilling rig

摘要:

为应对深地探测工程对特深孔地质钻探装备提出的新要求，“十三五”国家重点研发计划立项开展5000 m地质岩心钻机的研发。作为钻机核心部件的主绞车，需要满足自动化、智能化钻探需求。在调研了主绞车的研究发展现状基础上，借鉴石油钻机绞车的结构，确定了本主绞车运行参数及方案，并对关键零部件进行了设计与选型，完成了主绞车的设计。经过验算，主绞车运行参数能满足特深孔岩心钻探工艺的要求，并可以在地热、浅层油气探采等领域进行应用拓展。

Abstract:

The drawwork of 5000m geological core drilling rig is designed to meet the new requirements of deep exploration engineering for drilling equipment. Our project team was awarded the research and development program of 5000m geological core drilling rig. As the core part of the drilling rig, the drawwork needs to meet the requirements of automatic and intelligent drilling. After investigation of the development status of the drawwork, the project team determined the operation parameters and the scheme with reference to the structure of the oil drilling drawwork, and completed the design of the drawwork with design and selection of the key part. Through capacity checking calculation, it is proved that the operation parameters of the drawwork are reasonable, which can meet the requirements of ultra-deep hole core drilling technology, and can be applied in geothermal, shallow oil and gas exploration and production and other fields.
