【摘要】：顶驱的应用与发展迄今已有三十余年的发展历史。目前,使用较多的依然是电传动顶驱。但电动顶驱存在着电机结构尺寸庞大、调速依赖于复杂昂贵的电气系统、整机质量大、转动惯量大、输出扭矩不足的缺点；同时大功率电机的防爆特性难以保证,电机的大电流对高精度随钻测井仪器的精度也有一定的影响。同时在国内尚没有能够满足10000m科探井需要的顶驱；国外的采购成本有太高,并且采购国外的顶驱无法提高中国顶驱装备的研发能力,也违背了国家力主发展自身科学技术的宗旨。二十一世纪以来,现代机电液一体化技术飞速发展,并在工程机械领域得到成熟的应用,故此时进行适合10000m科探井的液压顶驱研究就是一个很好的选择。通过对国际上具有代表性的VARCO TDS11A这种一级传动结构的顶驱、IDS-1紧凑型顶驱、宏华现有的中空电机结构的直驱和海瑞克350T试制顶驱的结构研究,并结合国际专利的有效性和国内配套部件厂家的实际技术能力,确定了HTD-70顶驱的主体结构。该顶驱采用4套高速液压马达+行星减速器+4对称外啮合的静音斜齿驱动的主传动装置。主传动装置与提升装置、旋转头总成、液压背钳、防喷器及水龙头-冲管总成构成了HTD-70的主体结构。结合10000m科探井的钻井工艺需求以及设备采购的经济性,确定了大吨位下套管时采用游车+大钩,钻井时采用液压顶驱的经济性装备配套模式；确定了HTD-70的主参数4500kN,最大转速300rpm(对应扭矩58500N.m),最大扭矩12000N.m(对应转速75rpm),钻井参数优于了TDS11A、IDS-1和海瑞克350T顶驱。采用Simulation X软件对这种大功率的液压顶驱的液压系统进行了仿真分析确定液压系统的详细形式和控制方式,优化了液压系统。由于该技术是第一次应用到这么大功率的液压设备上,其准确性有待检验。液压顶驱在厂内的试验,验证了设计参数的正确性,同时为工业现场的应用提供了参考。
[Abstract]:The application and development of top drive has a history of more than 30 years.At present, the use of more is still electric drive top drive.However, the electric top drive has many disadvantages, such as the large size of the motor structure, the speed regulation depends on the complicated and expensive electrical system, the whole machine has large mass, the moment of inertia is large, the output torque is insufficient, and the explosion-proof characteristic of the high-power motor is difficult to guarantee.The high current of motor also has certain influence on the precision of high precision logging tool while drilling.At the same time, there is no top drive in China that can meet the needs of 10000m exploration wells; the procurement cost of foreign countries is too high, and the procurement of foreign top drives cannot improve the research and development capability of China's top drive equipment.It also runs counter to the state's tenet of supporting the development of its own science and technology.Since the 21 century, the modern electromechanical and hydraulic integration technology has developed rapidly and has been applied in the field of construction machinery. Therefore, it is a good choice to study hydraulic top drive suitable for 10000m exploration well.This paper studies the structure of IDS-1 compact top drive with VARCO TDS11A, which is representative in the world, the direct drive of hollow motor and Harek 350T pilot top drive.The main structure of HTD-70 top drive is determined by combining the effectiveness of international patent and the actual technical ability of domestic accessory component manufacturers.The top drive adopts four sets of high speed hydraulic motor planetary reducer 4 symmetrical external meshing silent oblique teeth drive main drive device.The main structure of HTD-70 is composed of main transmission and lifting device, rotary head assembly, hydraulic back clamp, blowout preventer and faucet flush pipe assembly.Combined with the drilling technology requirement of 10000m exploration well and the economy of equipment purchase, the economic equipment matching mode of large tonnage casing down-casing and hydraulic top drive was determined.The main parameter of HTD-70 is 4500kN, the maximum rotational speed is 300rpm (corresponding torque 58500N.mN), the maximum torque is 12000N.m. the drilling parameters are superior to TDS11ANIDS-1 and Harek 350T top drive.The Simulation X software is used to simulate the hydraulic system of this kind of high power hydraulic top drive. The detailed form and control mode of the hydraulic system are determined and the hydraulic system is optimized.Because this technology is the first time to be applied to such high power hydraulic equipment, its accuracy needs to be tested.The test of hydraulic top drive in plant verifies the correctness of design parameters and provides a reference for the application of industrial field.
