Abstract
The invention discloses a drill stem mud scarping tool, which can effectively solve the problems of short service life, difficult loading and unloading, complex structure, and inability of recovering mud. The technical scheme for solving the problems is as follows: the drill stem mud scarping tool comprises a bushing body, a mud scrapping disc and a wearing ring; the mud scrapping disc is arranged in a circular groove of the bushing body, and swings radially and moves axially along with the drill stem to cause the force applied on the mud scrapping disc to be even; and the wearing ring is fixed with the bushing body. The utility model has simple structure, convenient and fast loading and uploading, long service life and low price, and can recover mud, thereby having great economic and social benefits.
Description
One, technical field
The utility model relates to the oil burnisher, and particularly a kind of drilling rod is scraped bricklayer's tool.
Two, background technology
Often want movable drilling tool and trip-out in the conventional oil drilling process, especially in trip-out process, the mud that the drilling rod external surface adheres to is usually trickled down on one's body rig floor and driller, on the one hand, the mud of trickling down on rig floor is unfavorable for driller's operation, has brought potential safety hazard, severe contamination environment; On the other hand, the foreign matter well that falls easily takes place in borehole open in the trip-out process, causes down-hole accident.Existing drilling rod is scraped the bricklayer and is had closed mud scraping disc, pneumatic scraper.Closed mud scraping disc need unload stacks and the big quadrel of lifting when installing and removing, and application life is shorter, and pneumatic scraper costs an arm and a leg, and complex structure is installed difficulty, changes the consumable accessory difficulty midway.At present, on-the-spot generally adopt the simple and crude bricklayer's tool of manually scraping, not only increased driller's labour intensity, polluted environment, and the mud that can not thoroughly the drilling rod external surface be adhered to is cleaned out.Therefore, develop a kind of long service life, to scrape bricklayer's tool imperative for loading and unloading drilling rod convenient, simple in structure and recyclable mud.
Three, utility model content
At above-mentioned situation, for solving the defective of prior art, the purpose of this utility model just is to provide a kind of drilling rod to scrape bricklayer's tool, can effectively solve weak point in application life, loading and unloading difficulty, complex structure, can not reclaim the problem of mud, the technical scheme of its solution is, the utility model comprises core-compensating body, mud scraping disc and wear ring, and mud scraping disc is contained in the cannelure in the core-compensating body, radially wobbles and moves axially with drilling rod, make mud scraping disc stressed evenly, wear ring and core-compensating body are fixed together.The utility model is simple in structure, and is easy to loading and unloading, fast, and long service life is cheap, can reclaim mud, has greatly economic and social benefit.
Four, description of drawings
Fig. 1 is a half sectional view of the present utility model.
Fig. 2 is the utility model vertical view.
Fig. 3 is a mud scraping disc vertical view of the present utility model.
Fig. 4 is that mud scraping disc of the present utility model is along A-A line sectional view.
Five, the specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model comprises core-compensating body, mud scraping disc and wear ring, it is characterized in that, mud scraping disc 3 is contained in the cannelure in the core-compensating body 1, radially wobble and move axially with drilling rod, make mud scraping disc stressed evenly, wear ring 2 is fixed together with core-compensating body.
As shown in Figure 1, said wear ring 2 and core-compensating body 1 are by screw together.
As shown in Figure 4, said mud scraping disc 3 is made of mud-scraping ring 7, first top board 5, first lower platen 10, second top board 6 and second lower platen 11, first top board and second top board be contained in mud-scraping ring above, first lower platen 10 and second lower platen 11 be contained in mud-scraping ring 7 below.
As shown in Figure 1, have through-core hole 12 on the said mud-scraping ring 7.
Said mud scraping disc 3 is to be made of mud scraping disc spare 13 and supporter 14 thereof, and mud scraping disc spare is contained on the supporter.
Said core-compensating body 1 outside is set with movable tongue 4.
As shown in Figure 4, said mud scraping disc 3 has a place to disconnect, and it is connected with board slot 9 at the plate tongue 8 of gap by suit, and the plate tongue is sleeved on the board slot.
The alternative simple and crude bricklayer's tool of manually scraping of the utility model reduces labor strength; Mud scraping disc can make mud scraping disc stressed evenly, long service life along with drilling rod radially wobbles and certain moving axially in the core-compensating body cannelure; Mud scraping disc is as consumable accessory, and it is convenient to change; During non-trip-out operation, the mud scraping disc of can dismantling plays the small bushing effect; Have replaceable wear ring on the core-compensating body, core-compensating body is durable in use.The utility model installation site is the same with existing small bushing, the small bushing effect of having held concurrently.
The utility model is simple in structure, and is easy to loading and unloading, fast, and long service life is cheap, can reclaim mud, has greatly economic and social benefit.
