Abstract
The utility model relates to the technical field of oil and gas field layered fracturing, in particular to a mechanical sliding sleeve switch tool. The inner wall of an upper connector of the tool is connected with the outer wall of the upper end of a switch main body, the outer wall of the lower end of the switch main body is connected with the inner wall of a lower connector, a spring is mounted between a switch key and the switch main body, the outer wall of the upper end of the switch key props the inner wall of the upper connector under the effect of the spring, the outer wall of the lower end of the switch key props the inner wall of the lower connector under the effect of the spring, and a groove with a right-angle step at one end is formed in the outer wall of the switch key. The mechanical sliding sleeve switch tool achieves safety and reliability of a switch sliding sleeve, the structure is simple, and the operation is convenient. Difficulty in grinding a switch sliding sleeve for batting or shooting darts, a ball seat and a dart in the prior art, and a defect of long operation period can be overcome.
Description
Technical field:
The utility model relates to a kind of oil gas field separate stratum fracfturing technical field, particularly a kind of mechanical type sliding sleeve switch instrument.
Background technology:
The separate stratum fracfturing of Oil/gas Well transformation is at present main to be relied on pitching or throws dartlike weapon and realize, after pressure break, and the brill of ball seat, dartlike weapon mill difficulty, duty cycle is long, and fracturing fluid is the row of returning in time, causes oil-gas Layer secondary pollution, affects fracturing effect.If do not process ball seat, dartlike weapon, can not keep latus rectum in pit shaft, affect subsequent job.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of mechanical type sliding sleeve switch instrument, and it is safe and reliable that this instrument has been realized switching sliding sleeve, simple in structure, easy to operate.Overcome existing pitching or thrown dartlike weapon switching sliding sleeve, ball seat, dartlike weapon bore mill difficulty, the deficiency that duty cycle is long.
Technical solution adopted in the utility model is: a kind of mechanical type sliding sleeve switch instrument, comprises top connection, switch main body and lower contact; Top connection inwall is connected with switch main body upper end outer wall, switch main body lower end outer wall is connected with lower contact inwall, mounting spring between on & off switch and switch main body, on & off switch upper end outer wall withstands on top connection inwall under spring action, on & off switch lower end outer wall withstands on lower contact inwall under spring action, has the groove that one end is right angle step on & off switch outer wall.
The beneficial effects of the utility model are: the utility model is owing to having adopted mounting spring and on & off switch, thereby have advantages of that switching sliding sleeve is safe and reliable, simple in structure, easy to operate.
Accompanying drawing explanation:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, a kind of mechanical type sliding sleeve switch instrument, comprises top connection 1, switch main body 2 and lower contact 4; Top connection 1 inwall is connected with switch main body 2 upper end outer walls, switch main body 2 lower end outer walls are connected with lower contact 4 inwalls, mounting spring 5 between on & off switch 3 and switch main body 2, on & off switch 3 upper end outer walls withstand on top connection 1 inwall under spring 5 effects, on & off switch 3 lower end outer walls withstand on lower contact 4 inwalls under spring 5 effects, have the groove that one end is right angle step on & off switch 3 outer walls.
During work, the utility model two ends are connected by screw thread with oil pipe column, and on & off switch 3 extends radially out under the effect of spring 5.In sleeve pipe tubing string, be lowered in process, on & off switch 3 is at radial compression lower compression spring 5 automatic drawing backs, when entering sliding sleeve inner core step, on & off switch 3 extends radially out, under right-angle side coordinates with sliding sleeve inner core right angle step, oil pipe column drags sliding sleeve inner core, when drawing force acquires a certain degree, the release of sliding sleeve of bushing inner core shell fragment, inner core setting in motion, when 45 ° of forward positions of on & off switch 3 front end run into sliding sleeve of bushing release step, on & off switch 3 is at radial compression lower compression spring 5 automatic drawing backs, the direct step of the direct step of on & off switch 3 and sliding sleeve inner core departs from, complete switch motion.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; As long as meet, use needs, all within protection domain of the present utility model.
