Description
Technical field
This utility model belongs to field of oil drilling, particularly relates to kick-off device during a kind of sidetracking.
Background technology
Since " 12 " period, country continues to strengthen cbm development and utilizes support, continues to implement
" large oil and gas fields and cbm development " national science and technology key special subjects.Due to China's coalbed methane reservoir condition tool
There are " three low one high " i.e. low saturation, hypotonicity, low reservoir pressure, feature that degree of metamorphism is high, make
Become the problems such as well yield is low, mining area coal bed gas is made a low multiple use, in conjunction with coalbed methane reservoir feature, many points
The special track well technology such as Zhi Jing, " U " type well become the important means of coal-bed gas exploitation, then casing sidetracking
SIDETRACKING TECHNOLOGY has obtained quick development in recent years, and the core of this technology has been intended to the most high efficiency
Window opening tool, whipstock instrument is again the parts that tool for milling window in casing is important.But currently used makes
Tiltedly device body is mostly overall structure, and deflecting surface is occurring that deflecting surface bottom is cut after abrasion of windowing for a long time
Measure inclination angle the biggest, lateral and reduce too much, it is impossible to meet demand of windowing, it has to discarded, at discarded deflecting
In device, the deflecting component wear of many whipstocks is serious and other parts still can use, and so causes and makes
The problems such as tiltedly device utilization rate is low, waste of material, service life are low.
Utility model content
In order to solve the problems referred to above, it is high that this utility model provides a kind of utilization rate, and the life-span is long, cost-effective
Deflecting surface dismountable kick-off device.
This utility model is achieved through the following technical solutions:
A kind of deflecting surface dismountable kick-off device, including the window instrument of repairing being sequentially connected with from top to bottom, in advance
Seal milling cone, upper guiding part, deflecting parts, bottom whipstock parts, under described upper guiding part
End is detachable connection with deflecting component upper ends, and described deflecting lower and bottom whipstock parts are can
It is detachably connected with；Described deflecting parts are up-small and down-big wedge structure, and described lozenges is provided with a groove,
Being provided with deflecting surface in groove, deflecting surface uses carbide alloy board, and described deflecting surface is bolted with groove.
Further, described upper guiding part bottom is provided with female thread, and deflecting section upper is provided with outer spiral shell
Stricture of vagina；Upper guiding part is threaded connection with deflecting parts.
Further, described deflecting lower is provided with female thread, and described bottom whipstock component upper ends sets
External screw thread, deflecting parts is had to be threaded connection with bottom whipstock parts.
Further, the top of described upper guiding part is fixed by welded seal with pre-sealed milling cone.
The beneficial effects of the utility model are: (1) has compared tradition whipstock monolithic construction, this deflecting
Device is designed as assembled, overcomes that tradition whipstock build is big, is inconvenient to the problem that manufactures and transport, Er Qieren
What parts damages, only need to change the parts of damage；(2) deflecting surface and deflecting part design are removable
The connected mode unloaded, only need to select hard alloy wear resistance material at frayed serious deflecting surface, it is not necessary to whole
Individual deflecting parts all use high-abrasive material, save material and cost；(3) after working long hours, deflecting surface
Serious wear, the carbide alloy board that only need to more renew, remaining part can be again with, improves whipstock each
The utilization rate of individual parts.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described in detail:
As it is shown in figure 1, a kind of deflecting surface dismountable kick-off device, including the window instrument 1 of repairing being sequentially connected with,
Pre-sealed milling cone 2, upper guiding part 3, deflecting parts 6, bottom whipstock parts 12；
Before entering down-hole, the top of upper guiding part 3 is fixed by welded seal with pre-sealed milling cone 2
It is an entirety, prevents whipstock from freeing skew in decentralization process or coming off；
Described upper guiding part 3 bottom is provided with female thread 4, and deflecting parts 6 top is provided with external screw thread 5；On
Portion's guiding part 3 is threaded connection with deflecting parts 6；Described deflecting parts 6 lower end is provided with female thread two
10, whipstock parts 12 upper end, described bottom is provided with external screw thread 2 11, and described deflecting parts 6 are oblique with bottom
Device parts 12 are threaded connection；Ensure between upper guiding part 3 and deflecting parts 6, deflecting parts 6
And will not occur axially and radially to offset between bottom whipstock parts 12；All parts can according to transport and
The mode that the needs manufactured carry out separately or assemble；If certain parts is along bad, the when of replacing, only need to rotate spiral shell
Stricture of vagina, changes new parts；
Described deflecting parts 6 are up-small and down-big wedge structure, and described lozenges is provided with a groove 9, groove
Being provided with the deflecting surface 7 corresponding with groove size in 9, deflecting surface 7 is connected by bolt 8 with groove 9, deflecting
Face 7 material is carbide alloy board, can quench carbide alloy board in a pre-installation and other improves hardness
With the process of wearability, improve its service life, in actual use, because long-term work makes hard
