新型1200HP直立井架电动拖挂钻机的研制

Development of the New Type 1200HP Upright Derrick Electrical Trailer-Mounted Drilling Rig

摘要: 针对常规车载钻机存在的智能化程度偏低，井架需采用绷绳固定，对井场地质要求高、空间大，搬家时间长等不足，研制了1200HP直立井架电动拖挂钻机。该钻机采用全数字交流变频控制技术，采用双节套装直立无绷绳井架，采用全拖挂外围设备方案，配套先进的井口机械化工具，同时具有快速拆装、移运的特征，钻机的各项指数符合API相关规范，可满足Φ 114mm钻杆，最大井深4000 m的现代钻井工艺要求，能满足当前国内外特殊地区的油气开发。该钻机的智能化和集成技术达到了国内外自走式陆地钻机的先进水平。

Abstract: Based on the deficiencies of the traditional truck-mounted drilling rig, such as, the low degree of the intelligence, the adoption of guylines to fix the mast, the high requirement for wellsite geology and space, the long mobilization period, etc., we developed the new type 1200HP upright mast electrical trailer-mounted drilling rig. The drilling rig adopts all digital AC frequency conversion control technology, double telescoped upright mast without guyline and full trailer-mounted peripheral equipment proposal. It is equipped with advanced wellhead mechanical tools. Meanwhile, the rig will be with the characteristic of fast rig up and rig down, fast moving, and each index of the rig conforming the related API standard, meeting the modern drilling technology requirement of  Φ 114mm drill pipe and maximum drilling depth of 4000 m. And it can meet the present oil and gas development requirement for special area both in domestic and aboard. The intelligence and integration technology of the rig reaches the advanced level of the self-propelled the onshore drilling rig in the world.
