【摘要】：頂驅的應用與發(fā)展迄今已有三十余年的發(fā)展歷史。目前,使用較多的依然是電傳動頂驅。但電動頂驅存在著電機結構尺寸龐大、調速依賴于復雜昂貴的電氣系統(tǒng)、整機質量大、轉動慣量大、輸出扭矩不足的缺點；同時大功率電機的防爆特性難以保證,電機的大電流對高精度隨鉆測井儀器的精度也有一定的影響。同時在國內尚沒有能夠滿足10000m科探井需要的頂驅；國外的采購成本有太高,并且采購國外的頂驅無法提高中國頂驅裝備的研發(fā)能力,也違背了國家力主發(fā)展自身科學技術的宗旨。二十一世紀以來,現代機電液一體化技術飛速發(fā)展,并在工程機械領域得到成熟的應用,故此時進行適合10000m科探井的液壓頂驅研究就是一個很好的選擇。通過對國際上具有代表性的VARCO TDS11A這種一級傳動結構的頂驅、IDS-1緊湊型頂驅、宏華現有的中空電機結構的直驅和海瑞克350T試制頂驅的結構研究,并結合國際專利的有效性和國內配套部件廠家的實際技術能力,確定了HTD-70頂驅的主體結構。該頂驅采用4套高速液壓馬達+行星減速器+4對稱外嚙合的靜音斜齒驅動的主傳動裝置。主傳動裝置與提升裝置、旋轉頭總成、液壓背鉗、防噴器及水龍頭-沖管總成構成了HTD-70的主體結構。結合10000m科探井的鉆井工藝需求以及設備采購的經濟性,確定了大噸位下套管時采用游車+大鉤,鉆井時采用液壓頂驅的經濟性裝備配套模式；確定了HTD-70的主參數4500kN,最大轉速300rpm(對應扭矩58500N.m),最大扭矩12000N.m(對應轉速75rpm),鉆井參數優(yōu)于了TDS11A、IDS-1和海瑞克350T頂驅。采用Simulation X軟件對這種大功率的液壓頂驅的液壓系統(tǒng)進行了仿真分析確定液壓系統(tǒng)的詳細形式和控制方式,優(yōu)化了液壓系統(tǒng)。由于該技術是第一次應用到這么大功率的液壓設備上,其準確性有待檢驗。液壓頂驅在廠內的試驗,驗證了設計參數的正確性,同時為工業(yè)現場的應用提供了參考。
[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.
