Description
Technical field
The utility model relates to petroleum drilling engineering technical field of underground, particularly relates to a kind of wall-attachment bistable jet torsion impact device.
Background technology
Along with the development of petroleum industry, in oil-gas exploration process, find that more and more having verified petroleum resources buries in deep formation, deep-well, ultradeep well have become a kind of trend of oil and gas development.But when using PDC drill bit in deep-well, ultradeep well, due to oil-gas reservoir bury deeply, high temperature, high pressure, stratum abrasiveness is strong, drillability is poor, Engineering Geologic Characteristics is complicated, drilling complexity situation is many, drilling engineering will be made to face a various difficult problem, cause the series of problems such as drilling life of bit in drilling process is not long, rate of penetration is low, well depth Quality Down, then affect whole drilling process and final economic benefit.
PDC drill bit is the important means for the speed-raising of non-object layer section, is specifically adapted to soft creeping into hard formation.Under normal drilling condition, PDC drill bit can shearing-crushing stratum continuously, when PDC drill bit creeps at hard formation, does not usually have enough moments of torsion to carry out broken formation rock, thus drill bit is stopped operating.Now start to assemble torque energy in drill string, drill string is distorted, and when the enough fractured rocks of torque energy of drill string, drill bit is by ultrahigh rotating speed rotational shear fractured rock.This phenomenon is exactly that stick slip vibration phenomenon appears in PDC drill bit in drilling process.
Laboratory test and field practice all show, the stick slip vibration that PDC drill bit produces causes the key factor that drill bit lost efficacy and drilling efficiency is low, can directly damage PDC cutting teeth, reduce the application life of drill bit and lower drilling tool.
Utility model content
The purpose of this utility model is to provide a kind of wall-attachment bistable jet torsion impact device, to solve the problem of the PDC drill bit stick slip vibration that prior art exists.
The utility model solves the technical scheme that its technical problem adopts:
A kind of wall-attachment bistable jet torsion impact device, primarily of housing, jet units, dividing cell and hydraulic system assembly composition, housing comprises top connection, lower contact and urceolus, jet units comprises shunting and splits, splitter, carbide alloy pressing plate and two, left and right outer plate, dividing cell comprises the shunting gland being arranged on jet units upper end, be connected to deflector and the shunting body of jet units lower end, hydraulic system assembly comprises fluid cylinder end cap, hydraulic cylinder, fluid cylinder cover, piston and piston blade, between top connection and shunting gland, copper packing and adjusting pad are set, copper packing, adjusting pad, shunting gland, jet units, deflector, shunting body, fluid cylinder end cap, hydraulic cylinder, fluid cylinder cover, piston, piston blade, top connection, lower contact, urceolus and thrust bearing are tightly connected successively.
Above-mentioned top connection be threaded between urceolus after soldering, be convenient to sealing; Soldering after lower contact and urceolus adopt stepped hole to coordinate, fixes some pins between lower contact and urceolus.
About above-mentioned jet units, two outer plates are fixed on carbide alloy pressing plate by alignment pin and lock bolt.
During the utility model uses at the scene, top connection is used for connecting downhole power tool or drilling rod; Lower contact is for connecting drill bit, and the cleaner for high-pressure drilling fluid that slush pump exports enters attachment element through top connection, and form high-speed jet, high-speed jet produces wall attachment effect in element manipulation chamber.If first attached wall is in right side, water under high pressure enters hydraulic cylinder by diversion mechanism passage, promotes hydraulic piston and clashes into lower contact anvil block.Lower contact screw thread is connected with drill bit, impact force reaches drill bit, complete once circumferential torsion impact, in piston stroke finally, the speed of piston slap lower contact anvil block is suddenly zero, and cylinder body inner fluid produces surge pressure, this pressure makes jet switch to the feedback signal of left channel by right channel by controlling road formation, after fluid is switched to left channel, enter hydraulic cylinder opposite side, then promote liquid cylinder piston and do return movement; Same when after piston movement to dead point, produce water hammer, jet flow alternation exports to right channel by feedback signal, so comes and goes and realizes percussion action.The backwater of passage, then by drain hole, is crossed aquaporin through the lateral access of fluidic lateral access, separate system, lower contact anvil block and is passed downwardly through bit port and flow out.
The utility model is installed between drilling tool and drill bit, utilize the fluid energy of part drilling fluid, runner switching is carried out by wall-attachment bistable jet original paper, drive internal piston, in the region closed, produce the circumference reciprocating impact of certain frequency, and put on PDC drill bit, with the drilling tool moment of torsion acting in conjunction of stable state in drill bit, realize torsion impact drilling well.While overcoming the sliding phenomenon of PDC drill chuck, balance drill string reverses concussion, improves the working environment of drill string matching component, extends the application life of drill string matching component, improve the energy transfer efficiency being driven to drill bit from rotating disk or top.
The beneficial effects of the utility model are:
1, the switching of wall-attachment bistable jet torsion impact device High-Pressure Water is completed separately by fluidic, without other moving components except hydraulic cylinder piston, and impactor reliable operation, long service life;
2, when wall-attachment bistable jet torsion impact device piston hammer impacts lower contact, do accelerated motion all the time, be conducive to improving single strike work;
3, wall-attachment bistable jet torsion impact device does not operationally have valvular opening and cut out, little to high-pressure duct system vibration, drilling tool stable working, and energy loss is few;
4, wall-attachment bistable jet torsion impact device internal construction is simple, and part is few, is conducive to impactor and starts, stop, installation, dismounting etc.;
5, the condition of work of wall-attachment bistable jet torsion impact device is not by the impact of the scouring media states such as confined pressure, temperature, Media density, has anti-high-voltage performance simultaneously, is suitable for deep-well and creeps into.
