Abstract
The invention discloses a whipstock which comprises a main body and a cover body, wherein an axial inlet is formed at one end of the main body, the axial inlet has an internal thread which forms a first connecting end, a second connecting end is formed at the end opposite to the axial inlet, a groove is formed between the first and the second connecting ends, the cover body is matched with the groove, the main body and the cover body form a column body, a radial outlet is formed on a side face of the column body, and an arc-shaped channel is between the axial inlet and the radial outlet. The whipstock is characterized in that the radial outlet and the arc-shaped channel are formed by closing the main body and the cover body. The whipstock disclosed by the invention is firm and convenient in connection.
Description
Technical field
The present invention relates to the oil equipment technical field, spray the radially whipstock in hole creating technology field especially for the high-pressure hydraulic in the oil output measure.
Background technology
High-pressure hydraulic sprays radially that hole creating technology is used to spray the producing horizon position, develops into a kind of oilfield stimulation technology of high-efficiency and economic gradually.In pore-forming jetting operation radially, at first on sleeve pipe, bore and open an aperture, at this moment need to use whipstock to make and window tool string on direction, to finish and window perpendicular to production tube.Whipstock commonly used at present all is to cover out a plurality of screws at the whipstock that is positioned at end face, uses screw and links to each other with anchor with flow string then.Because this kind connection is not very firm, also need to weld the screw junction usually again in the lower going-into-well.Because the screw thread of existing whipstock etc. all is to link to each other by screw, also will be before it is gone into the well through welding, use pretty troublesome and weld strength can't guarantee, it is not very firm causing whipstock, is easy to damage.And deflecting is directed inaccurate, influences construction quality.
Because the defective that above-mentioned existing whipstock exists, the inventor is actively studied innovation, founds a kind of whipstock of new structure, to improve the defective that general prior art exists.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the invention provides a kind of whipstock.Whipstock of the present invention is firm, and is easy to connect.
In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme:
Whipstock, comprise main body and lid, one end of main body has axial entrance, described axial entrance has internal thread and forms first link, an end relative with axial entrance forms second link, has groove between first link and second link, described lid and described groove are suitable, main body enough becomes a cylinder with lid, the side of described cylinder has radially outlet, axial entrance with radially is connected by curved channel between the outlet, wherein radially outlet is formed by main body and lid fastening with curved channel.
Further, the axis of described cylinder is crossed the plane at the place, bottom of groove.
Further, described main body is connected by bolt with lid.
Further, described main body is connected by bolt with lid.
Further, described whipstock also comprises rectilinear fluid passage, and described fluid passage is communicated with curved channel, and the outlet of fluid passage is positioned at the radially top of outlet, and fluid passage is fastened by main body and lid and forms.
Further, described second link has connecting thread.
Compared with prior art, beneficial effect of the present invention is:
1, whipstock of the present invention adopts the integral type design, and the screw thread by its two ends can directly be connected with other workpiece, connects fast, and connection firmly.
2, whipstock of the present invention separated into two parts diametrically is convenient to leave arc groove like this on entity, thereby forms curved channel by two parts snapping, is easy to processing and manufacturing.
3, whipstock of the present invention location is more accurate.
