Abstract
The utility model discloses an anti-blocking structure of a float collar float shoe. The anti-blocking structure of the float collar float shoe comprises a body, an upper valve body, a lower valve body and a one-way valve, wherein the upper valve, the lower valve body and the one-way valve are arranged in the body. A circulating hole which is communicated up and down is formed in the middle of the upper valve body, a circulating channel is formed in the lower valve body, the one-way valve selectively opens/closes the circulating hole from the lower portion of the upper valve body, and an anti-blocking device is multiple protrusion blocks which are arranged on the upper end face of the upper valve body of the periphery of the circulating holes. The protruded anti-blocking structure is simple in structure, and easy to machine, the protrusion blocks can eject a falling article so as to prevent the circulating hole from being fully blocked, be capable of normally circulating or cementing a well, and ensure smooth follow-up work.
Description
Technical field
The utility model relates to the Cementing instrument, particularly relates to a kind of anti-blockage structure of float collar float plug.
Background technology
Float collar float plug is the common tool in well cementing operation, and the circulation port obstruction accident that causes because of trouble of lost tool in hole in well cementing operation also happens occasionally, and has affected carrying out smoothly of follow-up work.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-blockage structure of float collar float plug, makes in the situation that there is trouble of lost tool in hole can not stop up circulation port.
The technical solution of the utility model is as follows for this reason:
A kind of anti-blockage structure of float collar float plug, described float collar float plug comprises body, is arranged on intrinsic upper valve body, lower valve body and one way valve, be formed with the circulation port of up/down perforation in the middle part of described upper valve body, be formed with circulation canal on described lower valve body, described circulation port is optionally opened/closed to described one way valve from the bottom of upper valve body, and described preventing clogging up device is a plurality of protruding blocks that are arranged on the upper valve body upper surface of circulation port surrounding.
Preferably, described each protruding block all is disposed radially, and evenly distributes in the surrounding of described circulation port.
Preferably, the inner of described protruding block extends to the upper port place of described circulation port, and the height of protruding block is 25～30mm.
This convex type anti-blockage structure is simple, easily processing, is applicable to the float collar float plug of all structures, comprises spring-driven, tongue plate type, float-ball type etc.The great advantage of this structure is that valve top is not same plane, falls within circulation port top as junk, and protruding block can prevent that circulation port from being blocked fully with junk jack-up, thereby can normal circulation or well cementation, has guaranteed carrying out smoothly of follow-up work.
Description of drawings
Fig. 1 is the schematic diagram of the utility model float collar float plug anti-blockage structure.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, float collar float plug comprises body 1, is arranged on upper valve body 3, lower valve body 6 and one way valve 4 in body 1.Be formed with the circulation port of up/down perforation at upper valve body 3 middle parts, be formed with circulation canal on lower valve body 6, one way valve 4 bottom from upper valve body 3 under the effect of spring 5 seals described circulation port, and described preventing clogging up device is a plurality of protruding blocks 2 that are arranged on the upper valve body upper surface of circulation port surrounding.
Each described protruding block 2 all is disposed radially, and evenly distributes in the surrounding of circulation port, thereby can reach better anti-clogging effect.
Preferably, the inner of described protruding block 2 extends to the upper port place of described circulation port, and the height of protruding block is 25～30mm.
