Abstract
The utility model discloses a torsional impact drilling tool, which is capable of applying high frequency torsional impacts to a drill bit in a drilling project. The utility model drilling tool has a technical scheme that the torsional impact drilling tool is mainly composed of a drill collar nipple, a torsional impact generator and a connecting body. The drill collar nipple and the torsional impact generator are connected through the connecting body clearance and positioned by a spline. A diversion cover is fixed on a hammer seat. A hollow chamber formed between the diversion cover and the hammer seat is sequentially provided with a cut-off nozzle, a screen pipe, a positioning sleeve and an impact hammer from inside to outside. The screen pipe is fixed with the hammer seat. The impact hammer, the positioning sleeve, the screen pipe and the hammer seat are respectively provided with a through hole circumferentially. An impact hammerhead and a starting hammerhead are processed on the impact hammer. The tool in the utility model is equipped between the drill collar and the drill bit which receives drill string rotating torque and meanwhile receives the high frequency torsional impacts generated by the impact hammer when the impact hammer is driven by the fluid. Compared with other drilling tools, the drilling tool in the utility model can generate high frequency torsional impacts, eliminate the drill bit sticking and sliding phenomena, raise the penetration rate of relatively hard or abrasive strata, prolong the service life of the drill string matching parts such as the drill bit, improve the drilling efficiency and reduce the drilling cost.
Description
Technical field
The utility model relates to downhole tool field in the drilling engineering.
Technical background
There is the problem of following several respects in drill bit in use:
(1) in the drilling process, sticking-sliding, bit freezing phenomenon that drill bit has usually, drill string is always tightened as clockwork spring, treat that moment of torsion gathers, discharge fast again, this engineering problem is comparatively serious, and drill string reverses concussion, make whole drilling process instability, to having a negative impact in application life of drill bit, drill string matching component.
(2) for than hard formation or abrasive layer, the depth of tooth penetration of drill bit is not enough, and rate of penetration has much room for improvement.
That uses in the drillng operation at present all kinds ofly spins or can only produce axial impact force towards lathe turner's tool, not only can not solve drill bit sticking-sliding, bit freezing phenomenon, the instability of aggravation is crept on the contrary can shorten bit life.The TorkBuster torsional pulse generator of the U.S. (patent No.: US 6742609B2) adopt the turbine drives jump bit to produce the high frequency torsional pulse, (number of patent application: 200910058083.9) utilize helicoid hydraulic motor to drive jump bit, the pressure drops many, that consume of these two kinds of drilling tool consumable accessorys are big for the torsional impact drilling tool of Southwest Petrol University.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of torsional impact drilling tool, in the rotary drilling at present, on the one hand, has much room for improvement for the rate of penetration than hard formation or abrasive layer; On the other hand, as the drill bit of oil drilling---the sticking-sliding phenomenon of drill bit needs to be resolved hurrily.Therefore, press for a kind of rate of penetration, solution PDC drill bit that can improve hard or abrasive layer and glue-slide the downhole tool of phenomenon.Under existing drilling well system operating mode, this instrument converts the fluid energy of part drilling fluid to shaft bottom mechanical rock breaking power and direct acting on the drill bit high frequency, that circumferentially reverse, impingement dexterously, this can produce high frequency by a small margin the drilling tool of torsional pulse can make stable the creeping into of drill bit, tool interior does not have other drilling tools such as turbine or screw rod, few easy workout part, the pressure drop that consumes is few, long service life.The purpose of this utility model is exactly in order to improve the rate of penetration than hard formation or abrasive layer, and sticking-sliding phenomenon of eliminating drill bit provides a kind of torsional impact drilling tool.
For achieving the above object, this utility model has adopted following technical scheme: a kind of torsional impact drilling tool, mainly form, it is characterized in that by drill collar pipe nipple, torsional pulse generator and connected body: described torsional pulse generator mainly by fairing cap, the axle collar, jump bit, positioning sleeve, set upright circle, the nozzle that dams, screen casing, hammer seat, support ring and capping ring form; The drill collar pipe nipple outside, the torsional pulse generator is interior, the two connects with the connected body gap, locatees with spline; Fairing cap is last, and the hammer seat is following, and the inner cavity that forms in the two fixing back is followed successively by the nozzle that dams, screen casing, positioning sleeve, jump bit from inside to outside in the cavity; Jump bit, positioning sleeve, screen casing and hammer seat circumferencial direction have through hole; Be processed with on the jump bit and impact tup and start tup, impact tup and be enclosed in mainly in the impacting house of being made up of hammer seat, jump bit and fairing cap and can rotate, the startup tup is enclosed in the main startup storehouse of being made up of jump bit, positioning sleeve and capping ring and also can rotates; The upper and lower axle collar that is equipped with of jump bit; Positioning sleeve is supported by the support ring that is installed on the screen casing, is equipped with between positioning sleeve and the screen casing and sets upright circle; The drill collar pipe nipple is the pipe shape, and there is screw thread the upper end, and the lower end has spline to fasten the annular gap of formation mutually with the hammer seat outside; A hammer seat profile is cylindric, and a hammer seat honeycomb duct is arranged at top, and the spline that fastens with the drill collar pipe nipple is arranged at the bottom, hammer seat inside be about the hollow structure of UNICOM, top has and the corresponding cavity of jump bit profile, internal thread is arranged at the bottom; Positioning sleeve hollow structure, the outside have the U-shaped structure, and the tup profile is corresponding with starting, and through hole is along the circumferential direction arranged; Screen casing is the pipe shape, and fixing with the hammer seat, screen casing top circumferencial direction had chute, and the lower circumference direction has current by pass; The nozzle that dams is the pipe shape, and screw thread is arranged at the bottom, is fixed on to cross between chute and the current by pass in the screen casing; The capping ring is between positioning sleeve and jump bit, and below fairing cap; Splitter box on the fairing cap; Connected body, the axle collar, to set upright circle, support ring, capping ring be the rolling element combination, or be that ring bodies or ring bodies make up;
This utility model has the following advantages:
Utilize fluid drives can produce the high frequency torsional pulse and can make the moment of torsion of drill string keep basicly stable and balance, reduce the application life that drill string reverses concussion, prolongs matching components such as drill bit, drill string.
The high frequency torsional pulse that this drilling tool produces acts directly on the drill bit, when improving rate of penetration, has eliminated sticking-sliding, the bit freezing phenomenon of drill bit, makes stable the creeping into of drill bit.
These drilling tool internal motion parts are few, and few easy workout part is simple in structure, can salvage.
