Abstract
The utility model relates to a wash pipe assembly for a power swivel, which is used for a top drive drilling device. The utility model comprises a spring seat (4), a moving ring (5), a static ring (6), etc. The utility model is characterized in that a lower joint (1) is connected with the spring seat (4) by a bolt (3), the lower joint (1) is connected with a fixing sleeve (2), the spring seat (4) is connected with the moving ring (5) by a pin (9), an upper joint (7) is sheathed outside the static ring (6), and a spring (8) is arranged between the fixing sleeve (2) and the spring seat (4). Proper compaction force is generated on the end surfaces of the rotary moving ring and the static ring by the pressure of the spring and a sealing medium, and a layer of very thin liquid film is kept between the end surfaces, which reaches a sealing purpose. The utility model has the characteristics that sealing service life of the utility model is extended, and pressure which a disk root can bear is enhanced to extend the operation period of the top drive drilling device and reduce the operation costs of the top drive drilling device, compared with a normal wash pipe packing.
Description
Technical field
The utility model belongs to the washing pipe assembly of petroleum and natural gas drilling rig power swivel part, specifically, is oil and gas well drilling water tap washing pipe assembly.
Background technology
In drillng operation, the high-pressure slurry of borehole pump output is transplanted on the top of top driving device or water tap by hose, is transplanted on the shaft bottom downwards by the washing pipe assembly.The washing pipe assembly is very crucial parts, and the high pressure that must be able to bear high-pressure slurry is leaked when entering spindle hole to prevent mud.The maximum pressure value that present washing pipe packing can bear is 35MPa, can not satisfy the requirement that top driving device bores darker oil well.
Summary of the invention
The purpose of this utility model is to provide a kind of oil and gas well drilling water tap of a kind of employing washing pipe assembly, this washing pipe assembly can bear the mud pressure greater than 35MPa, can satisfy top driving device and bore the requirement of darker oil well and simple in structure, easy accessibility, good airproof performance, the reliability height, thus the service cycle of top-drive drilling prolonged, reduced the operating cost of top-drive drilling.
The purpose of this utility model is achieved in that
Comprise lower contact 1, fixed cover 2, spring base 4, rotating ring 5, stationary ring 6 and top connection 7, lower contact 1 is connected by bolt 3 with spring base 4, lower contact 1 is connected with fixed cover 2, spring base 4 is connected by pin 9 with rotating ring 5, top connection 7 is enclosed within the outside of stationary ring 6, is provided with spring 8 between fixed cover 2 and spring base 4.
The utility model also adopts following technical scheme:
Sealing between rotating ring 5 and stationary ring 6 end faces is the end face seal form.
Advantage of the present utility model is: this washing pipe assembly can bear the mud pressure greater than 35MPa, can satisfy top driving device and bore the requirement of darker oil well and simple in structure, easy accessibility, good airproof performance, the reliability height, thereby prolonged the service cycle of top-drive drilling, reduced the operating cost of top-drive drilling.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is an external structure schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, bolt 3 connects lower contact 1 and spring base 4, and pin 9 connects spring base 4 and rotating ring 5.Lower contact 1 and main shaft are by being threaded, along with main shaft rotates and rotates.Rotate by bolt 3 connecting band flexible spring seats 4.Connect and then 5 rotations of drive rotating ring by pin 9.Top connection 7 is connected with gooseneck, transfixion.Sealing between rotating ring 5 and stationary ring 6 end faces is end face seal, by the pretightning force of spring 8 and mud pressure between its end face, form one deck as thin as a wafer liquid film and reach the purpose of sealing.Fixed cover 2 and lower contact 1 mainly play the safeguard protection effect by being threaded.
Fig. 2 is construction profile figure of the present utility model, and the utility model integral body is the external structure with the cylinder staving as can be seen.
Claims (2)
1, oil and gas well drilling water tap washing pipe assembly, comprise lower contact (1), fixed cover (2), spring base (4), rotating ring (5), stationary ring (6), top connection (7), it is characterized in that: lower contact (1) is connected by bolt (3) with spring base (4), lower contact (1) is connected with fixed cover (2), spring base (4) is connected by pin (9) with rotating ring (5), top connection (7) is enclosed within the outside of stationary ring (6), is provided with spring (8) between fixed cover (2) and spring base (4).
2, oil and gas well drilling water tap washing pipe assembly according to claim 1 is characterized in that: the sealing between rotating ring (5) and stationary ring (6) end face is the end face seal form.
