Abstract
The utility model relates to a non-contact pneumatic mud scraper for automatically clearing drilling tool mud in the oil field drilling process, which comprises an upper disc (1), a lower disc (2), a valve (3), a tee joint (4), a gas collector (5) and a gas supply pipe (6). The mud scraper has the advantages of small volume, light weight, simple structure, convenient operation and the like, and is suitable for wide popularization and application.
Description
The utility model relates to a kind of rig tool that oilfield drilling is removed drilling tool mud automatically that is used for.
When wellbore construction pulls out of hole, in order to check drilling tool and to keep the drilling tool cleaning, need remove mud on the drilling tool with scraper.At present, the scraper that on-the-spot what use is manually-operated mostly, manually finish, the rubber strips of employing welding rod that has or wooden stick, O-ring seal etc. are squatted by the workman and are scraped mud at well head, and not only labour intensity is big, and the last mud of scraping drilling tool effectively often.
Task of the present utility model is to provide a kind of non-contact pneumatic scraper, the working method that this kind scraper adopts is pneumatic, directly do not contact with drilling tool, automatically remove the mud on the drilling tool neatly, thereby can alleviate labor strength greatly, overcome the deficiency of existing scraper.
The utility model is to realize like this.It is made up of last dish (1), lower wall (2), valve (3), threeway (4), gas collector (5), air supply pipe (6).Its assembling, architectural feature are as follows: lower wall (2) coils (1) by 4 support bars on it with going up of oblique upper uses clamp connection, lower wall one side is equipped with valve (3), the tube head that stretches out that two bifurcated tube heads of threeway (4) one sides are buckled by hose and clip and last dish (1) band gingival cyst of mucous gland in the newborn links to each other, and opposite side links to each other with air supply pipe (6), gas collector (5) and driller's console (7).During use, after lifting from out rotating disk on the drilling tool, the valve (3) of lower wall (2) one sides is opened, open upper and lower dish (1), (2), drilling tool is buckled into wherein: then, shut valve (3), on carry drilling tool, and the air cock of opening driller's operating console (7) is supplied gas; Gas is sent in the dish (1) through gas collector (5), air supply pipe (6), threeway (4), is ejected on the drilling tool by pore, can reach the purpose of cleaning drilling tool.When column has risen, valve (3) is opened, open upper and lower dish (1), (2), scraper is taken off get final product.In this scraper course of work, air feed, stop the supple of gas or steam and operate by driller's console.
The utlity model has advantages such as volume is little, in light weight, simple in structure, easy to operate, remove the mud on the drilling tool in the time of can being widely used in the wellbore construction trip-out automatically, to alleviate labor strength.Owing to work in contactless mode between this device and the drilling tool, rely on pneumatic removing mud, thereby do not have wearing and tearing, long service life.
Accompanying drawing is a structural representation of the present utility model.Wherein, label 7 is a driller's console.
Below in conjunction with the accompanying drawings to applying with explanation in fact.
In the utility model, last dish (1) is by two semicircles 1/2, and " the pipe butt joint forms; two parts joint one side is that hinge connects; the hinge both sides are welded out the tube head that a band gingival cyst of mucous gland in the newborn is buckled respectively; so that link to each other with threeway two bifurcated tube heads with clip with hose; opposite side is that crops for rotation match; two parts can be opened, closure, be evenly equipped with the nozzle (pore) of 12-16 diameter 1-2mm on the pipe, these nozzles can directly be holed and apply carbide alloy on pipe and be got final product, and its jet angle becomes 30-60 ° of angle downwards with horizontal plane.Lower wall (2) is also by two semicircles 1/2 " the pipe butt joint forms; diameter is greater than last dish (1); be welded with 4 support bars on it; relative in twos; that post upper slopes inwardly, so that link to each other with clip with last dish, two parts pipe joint one side hose and clamp connection; opposite side is equipped with valve (3), but closure or openness.The finished parts of gas collector (5) for using on the rig.
Claims (3)
1, a kind of non-contact pneumatic scraper, form by last dish (1), lower wall (2), valve (3), threeway (4), gas collector (5), air supply pipe (6), it is characterized in that: lower wall (2) coils (1) by 4 support bars on it with going up of oblique upper uses clamp connection, lower wall one side is equipped with valve (3), the tube head that stretches out that two bifurcated tube heads of threeway (4) one sides are buckled by hose and clip and last dish (1) band gingival cyst of mucous gland in the newborn links to each other, and opposite side links to each other with air supply pipe (6), gas collector (5) and driller's console (7).
2, non-contact pneumatic scraper according to claim 1, base is characterised in that, last dish (1) is formed by two semicircle pipe butt joints, two parts joint one side is that hinge connects, the hinge both sides are welded out the tube head that a band gingival cyst of mucous gland in the newborn is buckled respectively, opposite side is that crops for rotation match, and is evenly equipped with 12-16 nozzle that applies with carbide alloy on the pipe, and its jet angle becomes 30-60 ° of angle downwards with horizontal plane.
3, non-contact pneumatic scraper according to claim 1, it is characterized in that, lower wall (2) is formed by two semicircle pipe butt joints, relatively be welded with 4 support bars that tilt obliquely upward on it in twos, two parts pipe joint one side hose and clamp connection, opposite side is equipped with valve.
