The adjustable curved shell of a tooth-embedded screw drill comprises an upper shell (1), a double-pin pipe nipple (3), a sliding sleeve (4), a flat key (6) and a lower shell (5). The axial lines of screw threads at both sides of the double-pin pipe nipple (3) form an included angle, the top end of the double-pin pipe nipple (3) is connected with the upper shell (1) through a screw thread, the bottom end of the double-pin pipe nipple (3) is connected with the lower shell through a screw thread, the sliding sleeve (4) is arranged on the excircle of the double-pin pipe nipple (3) between the upper shell (1) and the lower shell (5), the flat key (6) is arranged on the double-pin pipe nipple (3), and the bottom end of the upper shell (1) and the top end of the sliding sleeve (4) are provided with inter-embedded teeth (8). The utility model has the advantages that the structure is simple, the angle is easy to adjust, the positioning is accurate and the curved shell can be effectively prevented from having angle changes during the drilling operation.
Description
Affiliated technical field
The utility model relates to a kind of oil and gas development with the adjustable curved housing of helicoid hydraulic motor, especially relates to the adjustable curved housing of a kind of castellated helicoid hydraulic motor.
Background technology
Along with the continuous development of petroleum natural gas exploration technology, drilling technology, drilling technologies such as directional well, cluster well, horizontal well obtain application more and more widely.Helicoid hydraulic motor is as the main drilling tool of directional well, cluster well, horizontal well, need have stronger deflecting ability and than the build angle rate scope of broad, and can be according to the drilling technology needs, adjust the architectural characteristic of drilling tool, according to the drilling design requirement, select the curved housing of helicoid hydraulic motor of different angles, to satisfy the requirement of different build angle rate drilling technology.At present, helicoid hydraulic motor is bent housing and is divided into curved housing of fixed angle and the curved housing of adjustable angle, and the curved housing of adjustable angle has curved housing of manual adjustment angle and electrodeless adjustable angle to bend 2 kinds of housings.The helicoid hydraulic motor that the curved housing of fixed angle is installed can only satisfy the requirement of a certain fixing build angle rate, and different deflecting demands just need to change the helicoid hydraulic motor that the curved housing of different angles is installed, and increase deposit of tools, construction operation cost height.Existing electrodeless adjustable curved housing has the function of adjusting the bent housing angle in well head control, and its shortcoming is to adjust inconveniently, in the time of accurately adjusting to a certain angle, often needs repeatedly the repeatable operation test, adjusts precision and has error, construction operation inconvenience.
Manually adjust the curved housing of angle and be on ground according to the operation needs, will bend housing and adjust to needed angle, be characterized in that angle adjustment is convenient, accurately.Disclosed Chinese utility model patent on March 2 (CN2157978Y) " helicoid hydraulic motor special adjustable angle is bent housing unit " in 1994, the curved housing of this adjustable angle is made up of last pipe nipple, two pin thread pipe nipple, outer support set, flat key, following pipe nipple, and is simple in structure, easy to adjust.The curved housing of this adjustable angle in creeping into operation on pipe nipple easily rotate, cause the variation of curved housing angle, cause drillng operation can not realize design object.
The utility model content
In order to overcome the easily generation angle variation in creeping into operation that the adjustable curved housing of existing helicoid hydraulic motor exists, cause drillng operation can not realize the deficiency of design object, the utility model provides a kind of castellated helicoid hydraulic motor adjustable curved housing.
The technical scheme that its technical problem that solves the utility model adopts is: castellated helicoid hydraulic motor is adjustable, and curved housing comprises upper shell, two pin thread pipe nipple, sliding sleeve, flat key, lower house, the axis of two pin thread pipe nipples two ends screw thread has an angle, two pin thread pipe nipples upper end is threaded with upper shell, two pin thread pipe nipples lower end is threaded with lower house, on two pin thread pipe nipple cylindricals between upper shell and the lower house sliding sleeve is installed, on two pin thread pipe nipples flat key being installed is the sliding sleeve radial location, and there is chimeric tooth embedding mutually upper shell lower end and sliding sleeve upper end; Upper shell and two pin thread pipe nipple are equipped with sealing ring between radially; Lower house and two pin thread pipe nipple are equipped with sealing ring between radially.
The beneficial effects of the utility model are, and are simple in structure, are convenient to angle adjustment; Accurate positioning can effectively avoid curved housing angle in creeping into operation to change, and satisfies the deflecting technology requirement of directed drilling.
Description of drawings
Fig. 1 is the adjustable curved shell structure schematic diagram of the castellated helicoid hydraulic motor of the utility model.
Fig. 2 is the adjustable curved housing schematic appearance of the castellated helicoid hydraulic motor of the utility model.
Among the figure: 1. upper shell, 2. sealing ring, 3. pair pin thread pipe nipple, 4. sliding sleeve, 5. lower house, 6. flat key, 7. angle mark, 8. tooth embedding.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 1, the castellated helicoid hydraulic motor of the utility model is adjustable curved housing comprises upper shell 1, two pin thread pipe nipple 3, sliding sleeve 4, flat key 6, lower house 5, and the axis of two pin thread pipe nipple 3 two ends screw threads has an angle; Two pin thread pipe nipples 3 upper ends are threaded with upper shell 1, and two pin thread pipe nipples 3 lower ends are threaded with lower house 5; On two pin thread pipe nipple 3 cylindricals between upper shell 1 and the lower house 5 sliding sleeve 4 is installed, between two pin thread pipe nipples 3 and the sliding sleeve 4 flat key 6 is installed, flat key 6 is sliding sleeve 4 radial locations, prevents that sliding sleeve 4 from rotating.There is mutually chimeric tooth embedding 8 upper shell 1 lower end and sliding sleeve 4 upper ends, and the chimeric trailing flank gap≤2mm of tooth embedding 8 double wedges and groove, upper shell 1 and sliding sleeve 4 be by chimeric tooth embedding 8 mutually, and angle changed once again after the angle adjustment that can effectively prevent curved housing was finished.
Two pin thread pipe nipples 3 two ends screw threads of the adjustable curved housing of the castellated helicoid hydraulic motor of the utility model are straight thread, in order to guarantee excellent sealing performance, sealing ring 2 are installed at upper shell 1 and two pin thread pipe nipple 3 between radially; Lower house 5 and two pin thread pipe nipple 3 are equipped with sealing ring 2 between radially.
The angle adjustment specific implementation process of the adjustable curved housing of the castellated helicoid hydraulic motor of the utility model is as follows: at first unscrew the connecting thread of lower house 5 and two pin thread pipe nipples 3, its distance can satisfy tooth embedding 8 and break away from chimeric getting final product; Then sliding sleeve 4 is moved down, the chimeric mutually tooth embedding 8 in upper shell 1 lower end and sliding sleeve 4 upper ends is separated; Rotation is adjusted upper shell 1 to required curved housing angle again; Screw the connecting thread of lower house 5 and two pin thread pipe nipples 3 at last, make the tooth embedding 8 of upper shell 1 lower end and sliding sleeve 4 upper ends chimeric mutually, so just finished the adjustment of adjustable curved housing angle.The utility model angle adjustment scope is 0 °～3 °.
The utility model adjustable angle, accurate, convenient and reliable, its tooth embedding structure can effectively avoid the angle of curved housing in the drillng operation to change; Reduce the deposit quantity of drillng operation, reduced the construction operation cost, improved drilling efficiency the helicoid hydraulic motor instrument.
