The Research Of The Whole Moving Technology Based On SZJ450D Desert Rig

As the development of oil industry and drilling technology, many drilling companies have expanded drilling area in the desert. Because many desert oilfield are in deep Wells and drilling are big volume, weight, drilling put forward more strict requirements to high removed performance of rig. Some drilling contractor, in order to reduce drilling cost, have put forward higher requirements to high removed performance of deep well rig in desert regions. Developed shifter of rig for desert and solving the transportation problem of rig in desert environment will win many development opportunities for our country in the international petroleum drilling market.Considering the rig in the desert is often used for long distance transportation, in this paper, the scheme of wheel removed the rig base and drill derrick integral move respectively. Rig substructure adopts two tractor drawing completed removed, drilling rig derrick and the hoisting system overall removed using horizontal move, tractor traction rig derrick crown back, derrick trailer support on the top of the location of the derrick leg, so as to realize the whole rig derrick. Power system and mud pumps move way similar to the base, a saddle type connection, tractor traction, tanks used sledges type, single pot removed. Transportation of road surface pavement for hard soil, removed to avoid in the process of turbulence, and quality big rig, inertial impact, so to ensure that the transit system combined with drilling rig is firm. In addition, the drilling work, removed the system away from the rig and doesn’t affect the normal work of the drilling rig. Design a move to rational overall arrangement, design fast and strong connection from the device.The drill whole removed because of the bad well site environmental stability is the key for the implementation of the technology. Removed system must ensure safety removed rig substructure and derrick. Rig substructure is composed of multiple modules, big volume, heavy load, the stress of the rig substructure removed the whole situation was very different from rig substructure work. So the integral move of rig substructure is rig the perilous state of the whole move, first of all, according to the center of gravity of the base distribution to calculate the force situation of each tire, predict the security of the tire, prevent the blowout. In addition, the ramp and test rig move can ramp, the barycenter offset will cause base, leading to desert tire force change, may be a flat tire, run a risk of tilting at the same time base. To prevent the happening of the dangerous situation above, under the premise of desert tire safety, calculate the ramp of the ramp and test to the greatest extent.Move the whole system in desert regions at transportation, will have loose sand and so on the road. Removed by the tractor traction of the base drag, tractor after entering the sand road, probably because of the sand shear strength is insufficient cause driving wheel slip. When slip rate reaches a certain value, the tractor would not be able to provide effective traction to drag the base, make the move system transport is blocked. So study the characteristics of sandy soil and tyre in the sand on the force analysis of transit system in the sand by has the vital significance. Tractor is driving gear, wheel slip is mainly occurred on the tractor’s driving wheel. First study of tractor’s own sand through sex, tractor to overcome its resistance, the surplus of traction drag base is removed.Removed device includes base move device of drilling rig, derrick removed device, power system removed device, mud pump removed device, tanks move device, etc. Derrick, mud pumps, tanks, power system load is relatively small, move move device in the process of bearing is safe. And base itself structure of large size, heavy load, move device carrying large, key ChengZaiJian prone to deformation and failure, need to focus on research, analysis of its structure characteristics, on the strength, stiffness analysis, improvement and optimization. Weight a total of about 380 tons of drill base, the base power is located at the rear of the base, after because of the length above the pedestal, so power directly and traction gooseneck via the ear plate, the pin connection, traction gooseneck head pressure on the axle of traction, because the stress is large, so want to separate out the detailed design, and using the finite element analysis software ansys to do strength, optimize the unreasonable places to improve, improve the structure of the removed safety.
