Description
Technical field
The present invention relates to drilling equipment field, in particular to a kind of particle impacting well test drill bit.
Background technology
Along with China's being continuously increased, at deep hard formation and complicated geological bar the demand of petroleum resources
The emphasis direction that petroleum resources is current In Oil Field Exploration And Development is sought under part.Improving hard formation bit speed is mesh
One of technical barrier above faced, and the principal element affecting hard formation bit speed has that formation hardness is big, grind
Mill property is strong, hole deviation etc. that drillability is poor, bigger, cause occurring in hard formation drilling process bit speed low,
The problems such as drilling period length, high cost, govern deep-well and the bit speed of ultradeep well and oil field prospecting are opened
The overall efficiency sent out.
PDTI company Curlett H.B., Sharp D.P and Gregory M.A. of the U.S. in 2002 et al.
Inspired by shooting bomb rock fragmenting thought, applied in drilling engineering field, used the water of drilling mud
Power energy, as driving force, is intended projectile by high speed hard spherical steel grit submodule and is carried out the rock of crushing hard, and pass through
Drilling fluid carries circulation, it is proposed that particle punching drilling (Particle Impact Drilling is called for short PID)
The new ideas of technology.And particle impacting drill bit is as the proposition of particle impact drilling technology and grows up
One class New well drilling rock crushing tool, has rapidly and efficiently in the strata drilling that hardpan and wearability are strong
Broken lithology energy, be mainly manifested in the inside and outside portion structure changing conventional bit, rely on cleaner for high-pressure drilling fluid punching
Hit, metallic steel particle high speed jet and gauge teeth, cutting tooth mechanism to break rock, bit speed is fast,
The pressure of the drill is low, and row cuts smooth and easy etc..
Particle punching drilling is to break rock based on high-speed dome converted steel particle impacting, and associating high speed water conservancy breaks rock
Breaking rock with machinery tooth is auxiliary a kind of new well drilling and rock crushing method, can be used for drilling some special strata section,
The hard formation that drilling speed declines particularly is caused because of comprcssive strength.This drilling mode changes the side on cutting stratum
Method, improves the utilization rate of energy.For extremely hard rock stratum, the broken rock machinery to be far smaller than than merit of steel bomb
The broken rock of tooth is than merit, and the Local Instantaneous pulse stress peak value of generation is high, it is sufficient to broken the hardest with penetration
Rock.The pressure of the drill and the more conventional drilling well of moment of torsion that need are much smaller, and substantially reduce the tired of drill string and drilling tool
Labor destroys (bore hard formation be common failure mode) probability, and bit wear is the least, less down-hole thing
Therefore the round trip number of times caused, shorten drilling period, reduce drilling cost.
The broken rock mode of particle punching drilling drill bit be utilize cleaner for high-pressure drilling fluid impact, converted steel particle clash into and
Cutter, the combined-breaking rock such as mechanism of gauge teeth.First, by high speed converted steel particle impacting
Broken rock, forms volumetric fracture hole, forms rock ansa under the comprehensive function of multiple nozzles, and rock ansa is released
Put original internal stress, form loose shape.It is then broken under the mechanism of gauge teeth and cutting tooth,
Form landwaste.Last landwaste, under the percussion of cleaner for high-pressure drilling fluid, returns to ground with drilling fluid.With
This mode, completes whole rock break-off process.
Owing to current particle impact drilling technology is also in the developmental stage that comparison is primary, not mature enough, directly
Use finished product drill bit to carry out experimentation cost the highest, therefore need badly a kind of for studying in particle impact drilling technology
The particle punching drilling experiment drill bit of the performance of drill bit, with to reasonable particle spraying angle, eject position
Experimental study, the realization for particle punching drilling provides reliable test parameters.
Summary of the invention
The technical problem to be solved is, provides one to can be used in studying particle punching drilling skill
The particle punching drilling experiment drill bit of the performance of drill bit in art.
Therefore, technical scheme is as follows:
Particle impacting well test drill bit, including main body, the top of described main body connects top connection, bottom
Multiple nozzle and multiple landwaste cleaning body, described nozzle and described landwaste cleaning body are installed and are cylinder,
Described landwaste cleaning body is arranged with the plane perpendicular of described main body, and multiple described nozzles are respectively by relative to institute
The axis stating main body tilts the screw installation of different angles on the body, is respectively provided with in each described nozzle
Having the runner becoming predetermined angle with this nozzle own axes, the end of described nozzle is additionally provided with for adjusting
That states the nozzle inner flow passage angle with the axis of described main body beats clamper.
Described main body includes drill main body and the cut drill body being bolted, and cut drill body is by recessed
Hook bolt is connected to connect on drill main body, can carry out for cut drill body aging in test, that damage
Change easily, reduce experimental cost, improve conventional efficient, and the position of cut drill body top nozzle can be changed
Put, reach the impact testing different nozzle locations to efficiency of breaking rock.
Wherein, the quantity of described nozzle can be three, and the quantity of described landwaste cleaning body can be two.
Particle impacting well test drill bit in the present invention, by selecting the specification of nozzle and by beating clamper
Nozzle circumferentially positioned is rotated, such that it is able to realize different channel sizes, jet angle in the range of 360 °
Degree, the isoparametric research of eject position, the research for particle impacting drill bit provides reliable test data, becomes
This is low, and efficiency is high；Landwaste cleaning body is connected on cut drill body by the way of welding, landwaste cleaning body
Rotational trajectory the track of nozzle is completely covered, the landwaste on nozzle track can be cleared up, reach protection spray
The effect of mouth.
