Description
Technical field:
The present invention relates to directional well and horizontal well casing pipe window sidetracking technical field, particularly to one for casing sidetracking
The device of instrument wireless drilling orientation.
Background technology:
Current domestic tool for milling window in casing has developed into hydraulic pressure, setting type whipstock (one of window opening tool), and generally should
With, existing tool for milling window in casing orientation all uses gyro to implement, but exposes two big subject matters in producing: one is top
Spiral shell orientation need to use wired winch to coordinate, and vehicle comes and goes inconvenience and the activity duration is long；Two be that horizontal well casing pipe is windowed and
Speech, due to wire cable in sleeve pipe free releasing maximum hole deviation at about 50 °, it is impossible to realize window opening tool at other High angle
The nearly window point of well section precisely orients, and delays and affects normal production operation.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of device for tool for milling window in casing wireless drilling orientation, should
Device achieves employing wireless drilling measurer with entering one time to be drilled into orientation under tool for milling window in casing, setting, window, and saves time
Laborsaving, it is possible to nearly windowing precisely orients and sets, and operating cost is low, improves window sidetracking technology further.Overcome existing
Gyrocompassing window opening tool uses inconvenience, wastes time and energy, it is impossible to the deficiency that enough nearly windowings precisely orient and set.
The technical solution used in the present invention is: a kind of device for tool for milling window in casing wireless drilling orientation, including
Transition top connection, eyes non magnetic drill collar and eccentric lower contact；Eyes non magnetic drill collar upper end connects transition top connection, and eyes bore without magnetic
Quickly lower end connects eccentric lower contact, is provided with main hydrophthalmia and secondary hydrophthalmia, transition top connection central passage and master in eyes non magnetic drill collar
Hydrophthalmia is connected, and secondary hydrophthalmia lower end is connected with eccentric lower contact central passage, and wireless drilling measurer positioning cycle is nested with
Internal in main hydrophthalmia and be fixed on the inwall of eyes non magnetic drill collar bottom, wireless drilling measurer is arranged on wireless drilling and measures
Instrument positioning cycle puts, and wireless drilling measurer positioning cycle puts and is provided with opening, and eyes non magnetic drill collar diapire sets
In respect of be connected externally to the lateral deviation circulation port that leads to, the opening that main hydrophthalmia is put by wireless drilling measurer positioning cycle with
Lateral deviation circulation port is connected, and main hydrophthalmia is connected by interior circulation port with secondary hydrophthalmia, and ball seat sliding sleeve is connected to by connecting pin
Sealing on main hydrophthalmia sidewall and by sealing ring, ball seat sliding sleeve blocks the interior circulation port on main hydrophthalmia sidewall, at ball seat sliding sleeve
The main hydrophthalmia sidewall of lower end is provided with baffle ring.
The invention has the beneficial effects as follows: the present invention uses wireless drilling measurer with entering a brill under tool for milling window in casing
Complete to orient, set, window, time saving and energy saving, it is possible to nearly windowing precisely orients and sets, and operating cost is low, the most perfect
Window sidetracking technology.
Accompanying drawing illustrates:
The present invention will be further described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention:
As it is shown in figure 1, a kind of device for tool for milling window in casing wireless drilling orientation, including transition top connection 1, eyes
Non magnetic drill collar 6 and eccentric lower contact 10；Eyes non magnetic drill collar 6 upper end connects transition top connection 1, and eyes non magnetic drill collar 6 lower end is even
Connect eccentric lower contact 10, in eyes non magnetic drill collar 6, be provided with main hydrophthalmia 7 and secondary hydrophthalmia 12, transition top connection 1 central passage and main water
Eye 7 is connected, and secondary hydrophthalmia 12 lower end is connected with eccentric lower contact 10 central passage, wireless drilling measurer positioning cycle set
8 to be placed in main hydrophthalmia 7 internal and be fixed on the inwall of eyes non magnetic drill collar 6 bottom, wireless drilling measurer be arranged on wireless with
Boring on measuring instrument positioning cycle set 8, wireless drilling measurer positioning cycle set 8 is provided with opening, eyes non magnetic drill collar 6
Being designed with and be connected externally to the lateral deviation circulation port 9 led on diapire, main hydrophthalmia 7 overlaps 8 by wireless drilling measurer positioning cycle
On opening be connected with lateral deviation circulation port 9, main hydrophthalmia 7 is connected by interior circulation port 11 with secondary hydrophthalmia 12, ball seat sliding sleeve 3
Being connected on main hydrophthalmia 7 sidewall by connecting pin 2 and sealed by sealing ring 4, ball seat sliding sleeve 3 blocks main hydrophthalmia 7 sidewall
On interior circulation port 11, main hydrophthalmia 7 sidewall of ball seat sliding sleeve 3 lower end is provided with baffle ring 5.
During use, eccentric lower contact 10 is connected on tool for milling window in casing, by under the present invention and tool for milling window in casing to setting
Counting position of windowing, connect kelly bar, turn on pump on well head drilling tool, drilling fluid is surveyed by transition top connection 1, main hydrophthalmia 7, wireless drilling
