Description
Technical field
The present invention relates to winning equipment field, be specially multistage cutting bit.
Background technology
Drill bit is the cutting tool that general awl or drilling and digging machine device adopt, to cut out circular hole.The general principle of drill bit makes drill bit trimming rotation, cutting workpiece, carries out eliminating drilling cuttings by drill flute again.Conventional drill bit mainly contains fluted drill, chit drill, centre drill, depth drill and cylindrical drill.Though reamer and counterbit can not be holed on solid material, also they are included into drill bit one class traditionally.
The concept of hybrid bit results from early 1930s the earliest, is but considered to unpractical at that time, or even irrational, but along with the development of 21 century advanced technology, hybrid bit comes true from illusion.Over nearly 100 years, multiple technologies all have great impact to drilling well industry.Rotary rig, rotary drilling-head, top drive and PDC(polycrystalline diamond) drill bit is some revolutionary technology, changes the mode of operator's drilling well.
Along with drilling operator promotes the increase of oil and gas reserves difficulty, innovation and the application of drilling technology have become larger challenge.Such as, Holes of Complicated Wells structural profile, the restriction of hard interlayer stratum and rig and equipment thereof adds the short-period potentiality of contracting, result in the breakage of high price instrument, and eventually reduces the economic benefit of operator.Although PDC(polycrystalline diamond) function of drill bit achieves significant improvement, and the poor efficiency that it also produces by high torque fluctuation and moment of torsion integral level affects dynamically.Similarly, the improvement of rock bit technology improves drilling machinery drilling speed (ROP), but also limits by by technology inherence the impact brought always.
Hybrid drilling technology is the innovation of Mode change, is the unitary patent design that gear wheel synthesizes with PDC drill bit.Its final purpose is the best attributes for utilizing every class drill bit, shortens their gap.Along with diamond bit cutting advantage and cut continuously and the rock crushing strength of rock bit, this prosthetic drill bit controls to make that interlayer stratum is residual to be well confirmed with steady drilling well and high-quality cutter cutting blade face.Laboratory test and execute-in-place confirm the benefit of complex technique.Compared with PDC drill bit, the advantage of composite drill bit: lower, compare the drilling torque be harmonious; Good oriented control is dynamic; Improve interlayer stratum durable reliability; Less twisting vibration.Compared with traditional rock bit: the potentiality that improve drilling machinery drilling speed (ROP); Less axial rotation.
Existing drill bit is all individual layer face, and in use procedure, drill bit easily weares and teares, and stock-removing efficiency is not high, although technology has had a lot of progress, still there is many weak points.
