Description
Technical field
The utility model relates to oil field drill string removing surface technical field of tools, is a kind of drill string gas desludging device.
Background technology
In oil drilling exploration, drill string is that an important tool is produced in drilling well, by kelly bar, drilling rod, brill very and the pipe string formed of other downhole tools form, be mainly used in drilling process, by drill string drill bit and ground are coupled together.Creep into drill string is to be immersed in the drilling fluid always, if need more bit change or inspection drilling tool in creeping into, will put on drill string from the down-hole come.Drilling fluid just is attached on the drilling tool when mentioning drill string, and we will clean out drill string with instrument, and we are mud-scraping apparatus this instrument, is indispensable instrument in our drillng operation.Its effect is cleaned out the drilling fluid on the drilling tool exactly, makes the drilling tool drilling fluid that being corroded property is very not strong corrode (after drill string proposes well head, owing to contact easier corrosion drilling tool with air).The surface of drill stem fettler that drilling well is at present used has two kinds, and a kind of is artificial mud-scraping apparatus, and another kind is a rubber circle mud-scraping apparatus.The structure of artificial mud-scraping apparatus mud-scraping apparatus is: one is about 400 mm to 500mm, wide about 50 mm to 80mm, and the flexible rubber of thick about 20 mm to 30mm, each fixes a hand-held handle of making of wood materials of using of column type two ends.Operating principle: carrying when boring, stood relatively over against the well head drilling tool by two people, everyone respectively takes a scraper that the rubber part is closely contacted with drill string, be bonded at drilling fluid on the drill string scrape from, thereby reach the purpose of clearing up drill string.The structure of rubber circle mud-scraping apparatus is that a race diameter is about 500mm, internal diameter is slightly less than drill pipe diameter 5 " (127mm), the cake of thick about 25mm constitutes.Operating principle: when carrying brill rubber ring is put into below the big quadrel, drilling tool friction rubber ring internal diameter reaches cleaning drill string purpose when carrying brill.Artificial mud-scraping apparatus is simple in structure, with low cost, easy to operate, but must have two people to stand in well head during operation.Two people's overhead are traveling systems of running up and down at a high speed, belong to drilling well one-level deathtrap, and this zone forbids that when traveling system turn round personnel enter strictly speaking, this with crane operation in the people that can not stand in the arm radius of gyration zone be a reason.The people needn't stand in the problem of well head when rubber circle mud-scraping apparatus had solved the traveling system running, but several problems are arranged: 1, must carry when boring at every turn and will adorn once, cumbersome, the workman of drilling team does not want to take the trouble sometimes, uses artificial mud-scraping apparatus again instead; If 2 rubber cracking, drill string is just scraped unclean; 3, winter rubber hardens, and it is also undesirable to scrape the mud effect.
Summary of the invention
The utility model provides a kind of drill string gas desludging device, has overcome the deficiency of above-mentioned prior art, and it can effectively solve the problem that existing drill string removing surface instrument is installed trouble, scraped the mud weak effect and have potential safety hazard.
The technical solution of the utility model realizes by following measure: a kind of drill string gas desludging device comprises support, ring pipe, shower nozzle and admission line; The ring pipe of at least one is fixedly mounted on the support, on ring pipe, be installed with at least three shower nozzles with the ring pipe intracavity inter-connection, the gas outlet of shower nozzle is all corresponding with the axis direction of ring pipe, one end of admission line and ring pipe is fixedly installed togather and with the ring pipe intracavity inter-connection, on admission line, be installed with valve.
Be further optimization and/or improvements below to above-mentioned utility model technical scheme:
Under the above-mentioned admission line cleaning fluid tank can be arranged, siphonal lower end is positioned at cleaning fluid tank, and siphonal upper end and admission line are fixedly installed togather and are interconnected, and is installed with valve on syphon.
The above-mentioned ring pipe outside can be installed with protective cover.
Above-mentioned shower nozzle can be skewed and be fixedly mounted on the ring pipe, the downward-sloping angle that is 15 ° to 20 ° of the axis of shower nozzle and horizontal plane.
The outlet passageway of above-mentioned shower nozzle can be bell mouth shape.
Above-mentioned ring pipe can be two and also is fixedly mounted on the support from top to bottom.
The utility model reasonable and compact in structure, installation, easy to use is carried out purge by shower nozzle ejection high velocity air to drill string, can reach well clear mud effect, and reduce potential safety hazard, has also greatly improved operating efficiency.
Description of drawings
Accompanying drawing 1 is looked the broken section structural representation for the master of the utility model most preferred embodiment.
Accompanying drawing 2 is the plan structure schematic diagram of ring pipe and protective cover in the accompanying drawing 1.
Coding in the accompanying drawing is respectively: 1 is ring pipe, and 2 is shower nozzle, and 3 is admission line, and 4 is valve, and 5 is cleaning fluid tank, and 6 is syphon, and 7 is protective cover, and 8 is drill string.
The specific embodiment
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
