Design Of Vehicle CBM Drilling Rigs And Research On Special Power Swivel

The research work carried out in this paper, combined with the Zhongcheng equipment manufacturing company development of CBM drilling rigs for the research project, through the investigation of China’s CBM production area drilling operation environment and drilling rig at home and abroad situation analysis, put forward the necessity and significance of coalbed methane drilling rig developed vehicle. Development of special drilling machine for CBM development in China, meet road areas of China’s coalbed gas conditions and environmental requirements, using conventional tools and wellhead tools, special CBM drilling equipment has the advantages of simple structure, high ratio of performance to price. On the basis of investigation, the formation of research and analysis report, determination of main technical parameters of the technical scheme of vehicle special CBM drilling rig and vehicle special CBM drilling rig; draw lessons from domestic and international forming technologies launched technology research on CBM drilling machine for the vehicle and its parts, design completed parts; using three-dimensional design software and the finite element analysis software to verify the design; complete the test prototype manufacturing and factory, the final field test is carried out to verify the product, form product shaping vehicle CBM drilling rigs.Vehicle special CBM drilling rig for hydraulic drilling rig, using special off-road chassis as vehicles, according to the operating mode of the integrated design of the drilling rig vehicles and rig, complete the design of reasonable layout and chassis rig components on the frame. Integrated design of on-board special CBM drilling derrick, crane, special power swivel, derrick telescoping derrick, through the telescopic hydraulic cylinder to realize the expansion and the promotion of the traveling system of the derrick, lowering function; crane with rotation function, meet the rig in the transportation and the working condition requirements; special power swivel slideway integration in the derrick telescopic section tap on, along the derrick up-down movement, anti-torque special power transfer to tap the derrick. Wellhead tools designed button punching pliers, button punching pliers and special power swivel shackle function with the completion of drilling rig. According to the function of drilling rig hydraulic and control system design, the whole hydraulic control rig. At the same time, some related design according to HSE requirements of drilling rig, the colors and logo design. Design of special drill coal-bed gas formation of complete vehicle.In this paper the design of special power swivel s are studied. Special power swivel of the body, a hanging beam, special power swivel dedicated bracket and the back clamp etc.. Special power swivel is one of the main bearing rig faucet components, is the torque power source, so the design of special power swivel is particularly important. In the design, first to the special power faucet design scheme is selected, determine the transmission scheme of large torque hollow motor, the main parts:a shell, a center tube and special power swivel bracket is calculated with design and. Using the finite element analysis software to design the special power swivel for verification, design of special power swivel to meet the design requirements.Based on vehicle special CBM drilling and special power swivel prototype test were studied in this paper, according to the performance parameters of vehicle special CBM drilling rig and the use condition, to determine the required test program vehicle special CBM drilling and special power swivel and related test, according to the test program of vehicle special CBM drilling and special power swivel were test, carried out routine test, plant to plant functional test2times, the field drilling test. Complete plant export drilling test a100m deep wells, drilling function on has carried on the preliminary inspection and perfect; completed drilling CBM well testing a904m deep, the rig’s function was tested, verified the rig and actual drilling operation adaptability.Through the research on CBM drilling rig design, vehicle test, complete the vehicle special CBM drilling and special power swivel all design research, analysis and validation verification and field test to design aided by finite element analysis software, vehicle special CBM drilling and special power faucet can meet the design requirements, the need for CBM development in China.
