Abstract

A multi-stage circulation head relates to oil machinery, particularly relates to an oil tool used for a wellhead with large inclined angle and horizontal angle, and comprises an upper joint (1), a lower joint (2) and a projection ball (3). A middle joint (4) is connected between the upper joint (1) and the lower joint (2) in a threaded manner; a screw (5) and a side through hole (6) are arranged on the pipe wall of the middle joint (4); a fastening platform is arranged on the inner wall of the middle joint (4); a tubular sliding sleeve (7) is arranged inside a cavity of the middle joint (4); the upper end opening of the sliding sleeve (7) is folded; a through hole (8) is arranged on the pipe wall of the sliding sleeve (7); a circulation sliding way (10) matching with the screw (5) is arranged on the outer wall of the sliding sleeve (7); the fastening platform is arranged on the lower portion of the sliding sleeve (7); a spring (11) and a thrust bearing (12) are further sleeved on the lower portion of the sliding sleeve (7); a tubular ball storage sleeve (13) is arranged inside the lower joint (2); and the projection ball (3) is an elastic body. The multi-stage circulation head has the advantages of saving drilling starting time, increasing working efficiency, reducing engineer manufacturing price and the like.

Description

Multistage hydraulic circulating head
Technical field
The utility model relates to petroleum machinery, is specifically related to the petroleum tool of a kind of use at big angle of inclination and level angle well head.
Background technology
In drilling process, the time regular meeting run into mud liquid passage and block, when running into this kind situation,, open bypass valve by the pitching pressurization, open another passage, realize normal circulation.And if can't solve when running into this kind situation again.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of reused multistage hydraulic circulating head is provided.
Technical solution of the present utility model is: it comprises, lower contact and pitching, on described, be bolted with the tubulose center tap between lower contact, be bolted with the screw that stretches into inwall on the center tap tube wall and be provided with by-pass prot, the center tap lumen wall is provided with Ka Tai and is provided with the tubulose sliding sleeve in the chamber, the sliding sleeve upper port is drawn in, its diameter is less than described pitching diameter, the sliding sleeve tube wall is provided with the through hole that cooperates with the center tap by-pass prot, sliding sleeve is on upper end and through hole, the outer wall at downside place is provided with the seal sealing, the sliding sleeve outer wall is provided with the circulation slideway that matches with screw on the center tap tube wall, sliding sleeve is provided with Ka Tai and is with spring and thrust bearing in the bottom, spring and thrust bearing are against between the card platform of center tap and sliding sleeve, be provided with the overcurrent section in the described lower contact and be provided with tubulose and store up ball cover in overcurrent section place, overcurrent section diameter is greater than storage ball cover external diameter, storage ball cover bottom is provided with diameter less than holding together mouth in the pitching diameter, and the storage ball cover holds together on the mouth in interior, the tube wall of downside is provided with flowing hole, and described pitching is an elastic body.
Technique effect of the present utility model is: it has the trip-out time of saving, increases work efficiency and reduces advantages such as construction costs.It is to use a kind of ideal tools at big angle of inclination and level angle well head; According to standard, all hydraulic circulating heads all have the risk of two big circulation interface to reduce to stop up; It is to allow the reverse circulating unique instrument of TFA; Because unique design, flow joint is opened before ball arrives at fishing joint, to prevent in the ball input process by crowded broken; This multistage hydraulic circulating head enters in the well and can be opened in the permanent position; But switch is 6 times at least, can increase the switch number of times if any specific (special) requirements.
Description of drawings
Fig. 1 is a sectional structure chart of the present utility model;
Fig. 2 partly cuts open structure chart for the utility model sliding sleeve;
Fig. 3 is the expanded view of the utility model sliding sleeve outer wall circulation slideway.
The specific embodiment
As Fig. 1, shown in 2 and 3, it comprises, lower contact 1,2 and pitching 3, on described, lower contact 1,2 are bolted with tubulose center tap 4, be bolted with the screw 5 that stretches into inwall on center tap 4 tube walls and be provided with by-pass prot 6, center tap 4 lumen walls are provided with Ka Tai and are provided with tubulose sliding sleeve 7 in the chambeies, sliding sleeve 7 upper port are drawn in, its diameter is less than described pitching 3 diameters, sliding sleeve 7 tube walls are provided with the through hole 8 that cooperates with center tap 4 by-pass prots 6, sliding sleeve 7 is on upper end and through hole 8, the outer wall at downside place is provided with seal 9 sealings, sliding sleeve 7 outer walls are provided with the circulation slideway 10 that matches with screw 5 on center tap 4 tube walls, sliding sleeve 7 is provided with Ka Tai and is with spring 11 and thrust bearing 12 in the bottom, spring 11 and thrust bearing 12 are against between the card platform of center tap 4 and sliding sleeve 7, be provided with overcurrent section 14 in the described lower contact 2 and be provided with tubulose and store up ball cover 13 in overcurrent section 14 places, overcurrent section 14 diameters are greater than storage ball cover 13 external diameters, storage ball cover 13 bottoms are provided with diameter less than holding together mouth 15 in pitching 3 diameters, storage ball cover 13 holds together on mouthfuls 15 in interior, the tube wall of downside is provided with flowing hole 16, and described pitching 3 is an elastic body.
