The invention relates to the technical field of drilling operation equipment, in particular to a lifting system of a double-rope-system deep well drilling rig, which comprises a base, a derrick and a lifting assembly mounted on the derrick, and is characterized in that the lifting assembly is used for avoiding the phenomenon that the deep well drilling rig uses too many pulley blocks, so that the speed of a high rope is too high and the rope is disordered; meanwhile, abrasion to the steel wire rope when the hoisting assembly is used can be reduced; the left winch and the right winch can work separately or jointly, when the left winch and the right winch work jointly, the rotating speed of the left winch and the rotating speed of the right winch are controlled to be the same through the electric control technology, and even if errors are generated, due to the fact that one drilling traveling rope is arranged on the first traveling block and the second traveling block, automatic mutual compensation can be achieved; synchronization of the first traveling block and the second traveling block is guaranteed, mechanical efficiency is improved, and energy consumption is reduced; the crown block can move on the top of a derrick to adjust the center of a wellhead.
本发明涉及钻井作业设备技术领域,具体为一种双绳系深井钻机的提升系统,包括底座,井架以及井架上安装的吊装组件,其特征在于,吊装组件用于避免深井钻机使用过多滑轮组而使得快绳速度过快产生乱绳的现象,同时可以减少吊装组件使用时候对钢丝绳的磨损;本发明左绞车和右绞车可以分开工作或者共同工作,左绞车和右绞车共同工作的时候,通过电控技术控制左绞车和右绞车转速相同,即使产生误差,由于第一游车和第二游车用的是一根钻井游绳,也可自动相互补偿,保证第一游车和第二游车同步,提高机械效率,减少能源消耗;本发明天车可以在井架顶部移动来调整井口中心。
