在我国钻机领域内独占鳌头的全数字化深井钻机——70DB钻机,日前在新疆克拉玛依白碱滩80288号井成功完成首井施工,这标志着国产深井钻机的科研水平,在关键技术上已与国外先进水平同步发展。这台由宝鸡石油机械有限责任公司与新疆石油管理局联合研制的7000米交流变频电驱动钻机,是集机、电、数字为一体化的新型钻机,采用了交流变频单轴齿轮绞车和主电机自动送钻技术。“一对一”控制的交流——直流——交流全数字变频技术,可满足内陆复杂油气井、超深井和海洋深水油气田开发及科学钻探井的需要,具有启动平稳、过载性能强、恒动率调整范围大、电动机无电刷火患等
Drilling rig in the field of drilling in the country of all-digital deep drilling rig - 70DB rig, a few days ago in Xinjiang Karamay Baijiatan 80288 well to complete the first well construction, which marks the domestic deep well rig scientific research level, in key technologies and foreign advanced Horizontal synchronization development. This set by the Baoji Petroleum Machinery Co., Ltd. and Xinjiang Petroleum Administration jointly developed 7000 m AC variable frequency electric drive drilling rig, is a machine, electricity, digital integration of new drilling rig, the use of AC variable frequency single-shaft gear winch and the main motor Automatic delivery of drilling technology. “One to one ” control of AC - DC - AC all-digital frequency conversion technology to meet the inland complex oil and gas wells, ultra-deep wells and deep ocean oil and gas field development and scientific drilling wells need to start with a smooth, strong overload performance , A large range of constant rate of adjustment, motor brushless fire and so on
