The upper end of the pressure difference drilling and reaming type window cutting taper is arranged inside the protective sleeve and connected and fixed with the protective sleeve through the cutting pin, the protective sleeve is welded with the inclined plane, the inclined plane is in threaded connection with the hydraulic slip type sidetrack drilling whipstock assembly, and the pressure difference drilling and reaming type window cutting taper, the high pressure line and the inclined plane are in sequential threaded connection. The MWD directional rapid window opening tool provided by the utility model realizes MWD directional rapid window cutting on the casing of the directional well or the extended reach well at a horizontal section or well deflection over 45 degrees, increases drilling speed, and reduces construction cost. The MWD directional rapid-window opening tool provided by the utility model overcomes the shortcoming that the conventional tool adopting a gyroscopic instrument cannot reach the window cutting site of the horizontal section, is easy to damage cables, and needs 2-3 times of trip constructions.
Description
Technical field:
The utility model relates to a kind of horizontal well, extended reach well and directional well casing window sidetracking technical field, particularly a kind of MWD orientation instrument of windowing fast that bores for.
Background technology:
In the intermediary and later stages that get into oil field development, adopt method recovery stopping production well point, well layer, well pattern, ratio brill offset well, the adjustment well of sidetracking relatively easy, and economically feasible.Sidetracked hole individual well expense is for boring 1/2～1/3 of the new well cost of a bite.Therefore, sidetracked hole has broad application prospects.
The casing window sidetracking technology is exactly a certain precalculated position at sleeve pipe, through grappling wedge deflection tool behind the gyrocompassing, forces and mills awl generation lateral force; On casing wall, mill out a side opening by predetermined direction; Make prime stratum exposed, sidetracking forms new well then, carries out recompletion again.
Along with the continuous development of SIDETRACKING TECHNOLOGY, horizontal well, extended reach well and directional well casing sidetracking have formed a kind of trend.Conventional sidetracking is windowed to construct and can't be met the demands, and is in particular in:
1, horizontal segment or hole deviation surpass 45 ° directional well, extended reach well section, and gyroscopic instrument is because the self structure characteristics, and the reason of down-hole mill resistance can't be descended a horizontal segment place of windowing.
2, gyro is the wire transmission signal of telecommunication, adopts outer fastening under the cable mode to bore, and is easy to cause drilling rod damage cable in the going down process.
3,, thereby increase construction cost because well depth surpasses 3000 meters, and common process must carry out making a trip for two to three times and carry out an envelope wedge deflection tool and change the construction of milling awl, has reduced bit speed virtually.
The utility model content:
The technical problem that the utility model will solve provides a kind of MWD orientation instrument of windowing fast that bores for; This tool implementation horizontal segment or hole deviation surpass 45 ° directional well, extended reach well sleeve pipe and window fast and bore a completion; Improve bit speed, reduce construction cost.The deficiency that overcome that existing instrument adopts gyroscopic instrument can't descend horizontal segment to window to locate, fragile cable need carry out making a trip for two to three times construction simultaneously.
The technical scheme that the utility model is taked is: bore the MWD orientation instrument of windowing fast for one time, by the pressure reduction drilling and reaming type window mill awl, cut off, protective sleeve, high pressure line, inclined-plane and hydraulic pressure pipe slips formula sidetracking wedge deflection tool assembly form; The pressure reduction drilling and reaming type places protective sleeve interior and fixing through cutting off connection on windowing and milling awl, protective sleeve and inclined-plane welding, and the inclined-plane is threaded with hydraulic pressure pipe slips formula sidetracking wedge deflection tool assembly, and the pressure reduction drilling and reaming type is windowed and is milled the screwed connection in order of awl, high pressure line, inclined-plane.
The beneficial effect of the utility model is: the utility model mills awl and hydraulic pressure pipe slips formula sidetracking wedge deflection tool assembly owing to adopted poor drilling and reaming type to window; Thereby but turn on pump circulates after under the utility model, getting into the precalculated position, starts the orientation works that the MWD instrument is implemented the instrument of windowing, through the conversion drilling fluid displacement; Reach a purpose of envelope wedge deflection tool; And orientation, seat envelope wedge deflection tool and the realization of windowing are bored for one time and are accomplished, and raising sidetracking (level) well rate of penetration reduces drilling cost; Mill that awl upper end places in the protective sleeve and connect fixingly through cutting off because the pressure reduction drilling and reaming type is windowed, thereby slacking off cuts off when meeting card and cuts off, and under the effect of protective sleeve, the wedge deflection tool well accident that falls can not take place yet.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the longitudinal section sketch map of Fig. 1.
The specific embodiment:
Like Fig. 1, shown in Figure 2, bore the MWD orientation instrument of windowing fast for one time, by the pressure reduction drilling and reaming type window mill awl 1, cut off 2, protective sleeve 3, high pressure line 4, inclined-plane 5 and hydraulic pressure pipe slips formula sidetracking wedge deflection tool assembly 6 form; The pressure reduction drilling and reaming type window mill that awl 1 upper end places in the protective sleeve 3 and through cut off 2 connect fixing; Protective sleeve 3 and inclined-plane 5 welding; Inclined-plane 5 is threaded with hydraulic pressure pipe slips formula sidetracking wedge deflection tool assembly 6, and the pressure reduction drilling and reaming type is windowed and milled awl 1, high pressure line 4, inclined-plane 5 screwed connection in order.
During the utility model work; The utility model is connected MWD not to be had on the magnetic, do not have at MWD to connect a heavy weight drill pipe on the magnetic, but turn on pump circulates after slowly the utility model being lowered into a place of windowing; Start the MWD instrument and implement the orientation works of the instrument of windowing; Through the conversion drilling fluid displacement, seat envelope instrument, the construction of windowing at last.
Be with being appreciated that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
