The utility model is characterized in that the difference between the area of the top of the jet and suction valve and the area of the bottom of the jet and suction valve, the pressure difference between an inlet and an outlet of the jet bearing machine, the pressure difference between the top and the bottom of the tool, the pressure difference between the interior and the exterior of the tool, and the speed difference between the jet and suction valve and the rushing hammer drive all mechanisms to move to generate water hammer pressure for striking the beakiron and transmitting kinetic energy to a drill bit for increasing the rock blasting effect of the drill bit.
Description
The utility model is that the oil field equipment technology is used for a kind of downhole tool that oil drilling improves efficiency of breaking rock.
At present, the oil drilling industry is at down-hole hard formation rock breaking method, be that rock bit extensional vibration is crushed and sheared brokenly rock under the pressure of the drill effect, the crushing efficiency of rock bit drilling well is decided by that the unit toe joint touches the load on the area, the degree of depth or formation hardness increase along with well, drill bit unit energy institute fragmented rock volume descends, and drilling efficiency reduces.
For solving this inefficient problem, more effectively finish rock impact and shear action, the U.S. has carried out rotation and has impacted the boring method research that combines, and U.S. Pan Mobil Oil Corp. develops double acting fluid power impactor, and the early stage experimental tool life-span is long and interrupt.Be extensive use of impactor in China's core drilling, but oil drilling and core drilling are widely different, the instrument of core drilling can not be used for oil drilling.China nineteen eighty-three, rotation oil drilling technology is impacted in my early start research, and develops double-purpose valve formula fluid power impactor (patent No. 85.2.02387.1), obtains and bores preferably and effect, but because of job insecurity, and the life-span is short does not promote.Daqing Petroleum Institute studied valve formula fluid power impactor again in 1993, ran into the problem in my research in the past equally.Chinese nova oil company oil drilling research institute in 1996 and exploration system of Changchun Geology university develop jet flow type shocker jointly, overcome the shortcoming of valve formula impactor, but this impactor shortcoming is very high to the drilling fluid requirement, pump pressure is too high during use, can not be used for deep-well, rubber piston and cylinder are simple and easy bad, and fluidic is too complicated, the difficult enforcement of general factory made, and cost is higher.
The utility model purpose is summed up me and is reached on other people the experience and lessons basis, and a kind of radio suction valve impactor of similar jet pump principle of new structure is provided, and solves the defective of aforementioned various impactors.
The utility model is achieved in that and meets the mechanisms that reciprocating direction control, transmission of power, three part compositions of power transmission are housed in the outer cylinder on drill bit.Inside and outside, produce radio suction valve under the pressure differential effect up and down and move back and forth, the different generation of the block stamp quality speed difference of radio suction valve and transmission of power, block stamp contacts the back and produces surge pressure with radio suction valve, promote radio suction valve and block stamp and hit hammering block, hammering block is passed to drill bit with impact kinetic energy, improves the drill bit rock breaking efficiency.
The utility model advantage, simple in structure, low cost of manufacture.The part that does not have the rubber piston assembly and be difficult to make, long service life.The pressure difference is bigger up and down in the instrument, is active in one's movements.Have and to adjust the frequency of impact part, be applicable to various stratum.
Concrete structure of the present utility model is provided by following enforcement and accompanying drawing.
Figure number 1-16 is the sectional drawing according to the radio suction valve impactor that the utility model proposes.
Describe in detail according to concrete structure principle details and the working condition that the utility model proposes below in conjunction with figure number 1-16.
Instrument mainly contains top connection (1), be connected in below the top connection (1) is cylinder barrel (2), the taper nozzle (4) that convergence is arranged below top connection (1), on nozzle (4) and below be useful on the adjustment circle (3) of adjusting frequency of impact, below the nozzle (4) valve pocket (5) of top area less than following area, holding spray apparatus (6) is positioned in the middle of the valve pocket (5), to hold the amount upper end that spray apparatus (6) is connected in block stamp (13) with screw thread, there is valve disc (7) upper end of block stamp (13), there is return spring (8) at the middle part, (9) and (10) be that the restriction block stamp is to the stop collar and the baffle plate of down stroke, prevent the empty stop collar of beating when (12) being punching, the instrument of the preventing well that falls, retaining watt (14) is housed on hammering block (15), hammering block (15) upper end is ten square, and it is contained in ten square openings of lower contact (16), and the moment of torsion of instrument cylinder barrel (2) is by ten square being delivered on the drill bit of hammering block (15) and lower contact (16).
Drilling fluid flows into the following nozzle (4) of top connection (1) through drilling tool, and at this moment flow velocity is very high, forms low-pressure area A.Drilling fluid flows into and holds spray apparatus (6), holds the shape of spray apparatus (6), and inlet is taper, and the middle part is the garden cylindricality, and bottom four sides have been opened the tubaeform of groove, and its effect is to reduce drilling fluid to enter kinetic energy at a high speed, and outlet pressure is increased.Drilling fluid is after hold spray apparatus (6) and come out, and the pressure of valve pocket (5) below is greater than the pressure in nozzle (4) A chamber.B chamber, valve pocket (5) outside communicates with annular space, during work because drill bit nozzle throttling action, tool interior pressure is greater than the B cavity pressure, and valve pocket (5) top A cavity pressure is less than valve pocket (5) below pressure, and pressure official post valve pocket (5) moves upward fast and valve disc (8) leaves.Valve pocket (5) is when moving upward, block stamp (13) also moves upward under action of reset spring and catches up with valve pocket (5), when the valve disc (8) on the block stamp (13) contacts with valve pocket (5) the bottom conical surface, the drilling fluid path is blocked, produce water attack, moment A chamber surge pressure is very high, and much larger than the B cavity pressure, valve pocket (5) and block stamp assembly move downward fast.The place that valve pocket (5) moves to spacing (9) is blocked, and block stamp assembly inertia moves downward segment distance impact hammering block, and hammering block is passed to the drill bit fractured rock with the impact force of accepting.When hammering block was accepted inertia impact, valve disc (7) separated with valve pocket (5) and restPoses.
Begin second action, because block stamp (13) assembly quality is greater than valve pocket (5) quality, the acceleration of valve pocket (5) is greater than block stamp assembly (13), movement velocity is poor, pressure differential, catching up with repeatedly, water attack, form discontinuity repeatedly, hit hammering block, kinetic energy is passed to the drill bit fractured rock.Ballistic work big or little is decided by mud pump delivery, block stamp quality and impact velocity.Change the thickness of the following adjustment circle of top connection (1), valve pocket (5) and nozzle (4) variable in distance, impact velocity just changes, and in the drilling process, changes discharge capacity, just can change impact velocity, ballistic work.
Valve pocket (5), stop collar (9), valve disc (7) are fragile parts, and material is selected 35CrMoAl for use, heat treatment hardness HRC55-60.Very heavy load is born in urceolus (2) and hammering block (15) and lower contact (16), and material is selected 40Cr-MnMo for use, and great impact is born on block stamp (13) bottom and hammering block (15) surface, and surface heat is handled HRC50-55.
