【摘要】：頂驅(qū)的應(yīng)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(dòng)頂驅(qū)。但電動(dòng)頂驅(qū)存在著電機(jī)結(jié)構(gòu)尺寸龐大、調(diào)速依賴于復(fù)雜昂貴的電氣系統(tǒng)、整機(jī)質(zhì)量大、轉(zhuǎn)動(dòng)慣量大、輸出扭矩不足的缺點(diǎn)；同時(shí)大功率電機(jī)的防爆特性難以保證,電機(jī)的大電流對(duì)高精度隨鉆測(cè)井儀器的精度也有一定的影響。同時(shí)在國(guó)內(nèi)尚沒有能夠滿足10000m科探井需要的頂驅(qū)；國(guó)外的采購(gòu)成本有太高,并且采購(gòu)國(guó)外的頂驅(qū)無法提高中國(guó)頂驅(qū)裝備的研發(fā)能力,也違背了國(guó)家力主發(fā)展自身科學(xué)技術(shù)的宗旨。二十一世紀(jì)以來,現(xiàn)代機(jī)電液一體化技術(shù)飛速發(fā)展,并在工程機(jī)械領(lǐng)域得到成熟的應(yīng)用,故此時(shí)進(jìn)行適合10000m科探井的液壓頂驅(qū)研究就是一個(gè)很好的選擇。通過對(duì)國(guó)際上具有代表性的VARCO TDS11A這種一級(jí)傳動(dòng)結(jié)構(gòu)的頂驅(qū)、IDS-1緊湊型頂驅(qū)、宏華現(xiàn)有的中空電機(jī)結(jié)構(gòu)的直驅(qū)和海瑞克350T試制頂驅(qū)的結(jié)構(gòu)研究,并結(jié)合國(guó)際專利的有效性和國(guó)內(nèi)配套部件廠家的實(shí)際技術(shù)能力,確定了HTD-70頂驅(qū)的主體結(jié)構(gòu)。該頂驅(qū)采用4套高速液壓馬達(dá)+行星減速器+4對(duì)稱外嚙合的靜音斜齒驅(qū)動(dòng)的主傳動(dòng)裝置。主傳動(dòng)裝置與提升裝置、旋轉(zhuǎn)頭總成、液壓背鉗、防噴器及水龍頭-沖管總成構(gòu)成了HTD-70的主體結(jié)構(gòu)。結(jié)合10000m科探井的鉆井工藝需求以及設(shè)備采購(gòu)的經(jīng)濟(jì)性,確定了大噸位下套管時(shí)采用游車+大鉤,鉆井時(shí)采用液壓頂驅(qū)的經(jīng)濟(jì)性裝備配套模式；確定了HTD-70的主參數(shù)4500kN,最大轉(zhuǎn)速300rpm(對(duì)應(yīng)扭矩58500N.m),最大扭矩12000N.m(對(duì)應(yīng)轉(zhuǎn)速75rpm),鉆井參數(shù)優(yōu)于了TDS11A、IDS-1和海瑞克350T頂驅(qū)。采用Simulation X軟件對(duì)這種大功率的液壓頂驅(qū)的液壓系統(tǒng)進(jìn)行了仿真分析確定液壓系統(tǒng)的詳細(xì)形式和控制方式,優(yōu)化了液壓系統(tǒng)。由于該技術(shù)是第一次應(yīng)用到這么大功率的液壓設(shè)備上,其準(zhǔn)確性有待檢驗(yàn)。液壓頂驅(qū)在廠內(nèi)的試驗(yàn),驗(yàn)證了設(shè)計(jì)參數(shù)的正確性,同時(shí)為工業(yè)現(xiàn)場(chǎng)的應(yīng)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.
