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, especially for the high-pressure hydraulic in the oil output measure, spray the radially whipstock in hole creating technology field.
Background technology
High-pressure hydraulic sprays radially hole creating technology and, for spraying the producing horizon position, develops into gradually a kind of oilfield stimulation technology of high-efficiency and economic.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 the window opening tool string complete and to window on the direction perpendicular to production tube.Whipstock commonly used, be all to cover out a plurality of screws at the whipstock that is positioned at end face at present, then uses screw and be connected with anchor with flow string.Because this kind of connection is not very firm, usually also need to weld the screw junction again in lower going-into-well.Because the screw thread of existing whipstock etc. is all to be connected by screw, it also will be through welding before going into the well, and using pretty troublesome and weld strength can't guarantee, it is not very firm causing whipstock, is easy to damage.And deviating and directing is inaccurate, affects construction quality.
Because the defect that above-mentioned existing whipstock exists, the inventor is research and innovation in addition actively, founds a kind of whipstock of new structure, the defect existed to improve general prior art.
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, 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 the first link, an end relative with axial entrance forms the second link, there is groove between the first link and the 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 between outlet, by curved channel, is connected, 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 and lid are bolted.
Further, described main body and lid are bolted.
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 and formed by main body and lid.
Further, described the 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, and connection is quick, and stable connection.
2, whipstock of the present invention is divided into two parts diametrically, is convenient to like this output arc groove 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.
The accompanying drawing explanation
The structural representation that Fig. 1 is whipstock of the present invention;
The structural representation of the main body that Fig. 2 is whipstock of the present invention;
The B that Fig. 3 is Fig. 2 is to structural representation;
The A-A that Fig. 4 is Fig. 2 cuts open figure;
The structural representation of the lid that Fig. 5 is whipstock of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but not as a limitation of the invention.
The structural representation that Fig. 1 is whipstock of the present invention; The structural representation of the main body that Fig. 2 is whipstock of the present invention; The B that Fig. 3 is Fig. 2 is to structural representation; The A-A that Fig. 4 is Fig. 2 cuts open figure; The structural representation of the lid that Fig. 5 is whipstock of the present invention.As shown in Figures 1 to 5, whipstock, it is a cylinder 1, one end of cylinder 1 has axial entrance 2, the side of cylinder 1 has and radially exports 3, axial entrance 2 with radially export 3 between by curved channel 4, be connected, wherein axial entrance 2 has internal thread and forms the first link 5, an end relative with axial entrance forms the second link 6.The second link 6 has connecting thread, with other workpiece, is threaded connection, and the connecting thread of the second link 6 can be internal thread or external screw thread.Certainly, the second link 6 also can adopt other modes to be connected with other workpiece, as interference fit, pin connection etc.Curved channel 4 also is communicated with a rectilinear fluid passage 7, and the outlet 8 of fluid passage 7 is positioned at the top that radially exports 3.When being positioned at the drill bit work that radially exports 3, the liquid of being drawn by fluid passage 7 carries out cooling, flushing to drill bit.The whipstock of the present embodiment consists of main body 101 and lid 102, and main body 101 comprises between the first link 5 and the second link 6, the first links 5 and the second link 6 having the groove 12 radially connected, and lid is suitable with the groove radially connected.Curved channel 4 and fluid passage 7 form by main body 101 and lid 102 fastenings.The axis of cylinder 1 is positioned on the bottom surface 11 of the groove 12 radially connected.Main body is connected by bolt 14 with lid.The cross section of the groove 12 radially connected is inverted trapezoidal.The groove 12 radially connected arranges and is the narrower inverted trapezoidal in bottom, can make lid 102 more closely firm with the combination of main body 101.The groove 12 radially connected is formed with shoulder 15.The setting of shoulder 15, can make between lid 102 and main body 101 be connected more firm.
Above embodiment is only exemplary embodiment of the present invention, is not used in restriction the present invention, and protection scope of the present invention is defined by the claims.Those skilled in the art can make various modifications or be equal to replacement the present invention in essence of the present invention and protection domain, this modification or be equal to replacement and also should be considered as dropping in protection scope of the present invention.
