Description
Technical field
The present invention relates to oil-well drilling equipment field, particularly a kind of spinner.
Background technology
Drilling well is one of topmost means of oil and natural gas exploitation, and what generally adopt at present is rotary system.During drilling well, along with the wearing and tearing of drill bit in the intensification of well or drilling process, need more bit change, when more bit change, need single drill pipe, drill string, coupled together (or taking apart) by the nipple between drilling rod, industrial being referred to as of oil drilling makes up a joint and round trip.
Drilling rod link closely or shackle time need very large moment of torsion and very low speed, but need very little moment of torsion and higher speed during contrary spinner.Often on current conventional drill adopt liquid gas hybrid power tong, carry out the upper shackle operation of drilling rod, its maximum shortcoming is that the little and large automatization level of volume of applicable caliber scope is low etc.; Often adopt Type B to clamp at the larger pipe of process, coordinate hydraulic catwork to complete the operation of shackle, its maximum shortcoming is that efficiency is low, poor stability.Round trip is the operation that drilling well labour intensity is maximum, human casualty accident the most easily occurs, and the current whole world has many countries all to replace manually carrying out round trip at research iron driller.
Spinner at present more common form of structure has wafer type and scissor two kinds of forms, mostly is Driven by Hydraulic Cylinder; Spinning roller arrangement form has three spinning rollers and four spinning rollers, two kinds of arrangement forms; Spinning roller drives has two motors, four motors, the fluid motor-driven patterns such as eight motors.The feature that the spinner of wafer type two four spinning roller is maximum is when clamping different pipes, Clamping Center is constant, the driving torque of four spinning rollers can be uniformly distributed, in order to be suitable for larger drilling rod scope, lateral length longer and to folder time need guide rail to lead, and hydraulic cylinder tension when clamping, cylinder diameter is larger.The maximum feature of scissor two four spinning roller spinners is that to overcome above-mentioned wafer type spinner lateral length large, (also there is hydraulic cylinder tension according to the difference that oil cylinder position is arranged in the problem needing guide rail to lead, the problem that cylinder diameter is large), but when clamping different drilling rod, Clamping Center can change, and four spinning rollers are different to the thrust of drilling rod, four spinning rollers are different to the driving force of drilling rod.The arrangement of three spinning rollers overcomes the problems referred to above, but bulky, complex structure.
Along with the development of automatic technology, drilling equipment automaticity is also in continuous improve, and on the moment of torsion of drilling tool, shackle equipment is also in continuous upgrading.Present state-of-the-art iron driller is developed into from the driving of original iron chains hoist engine, manual tongs, liquid gas hybrid power tong, the upper shackle equipment of automation plays an important role in raising drilling well production efficiency and security performance etc., and automatic implement replaces the manual labor of people at last.
