Description
Technical field
The utility model relates to well workover technology field, oil field, and the special tool of tube inner wall dirt is removed in particularly a kind of job site, is a kind of tube inner wall topping machanism.
Background technology
At present, in the oilfield downhole operation construction, for guaranteeing that jack rabbit can pass through oil pipe smoothly; The dirt of removing tube inner wall is one necessary operation, and prior art is to draw a sebific duct from the steam coach steam (vapor) outlet, at steel pipe of the terminal connection of sebific duct; The superheated steam that utilizes steel pipe to spray heats tube inner wall and cleans, because the part tube inner wall is stained with paraffin, former wet goods knot shape thing, when steam enters into the other end from oil pipe one end; Power obviously descends, and temperature also obviously reduces.If the tube inner wall wax deposition is serious, only lean on steam flush, need with for a long time could be cleaning up.With the oil pipe G.I.H, also need use the jack rabbit oil pipe, if tubing bending, jack rabbit can not pass through, and oil pipe does not meet the requirement of going into the well, and will give it up, and wastes time and energy, and production efficiency is low.
The utility model content
The purpose of the utility model is: a kind of tube inner wall rotary cleaning device is provided, and is power with steam, and through the rotating band dynamic cutter head rotation of impeller post, the cutting oil inside pipe wall reaches the purpose that tube inner wall cleans up.
The technical scheme that the utility model adopts is: the tube inner wall rotary cleaning device, mainly form by cutter head, cutter head locking handle, gland, clutch shaft bearing, impeller post, urceolus, second bearing and end cap.It is characterized in that: the threaded one end at urceolus is fixed with end cap, and end cap has centre bore, and steam channel is arranged around the end cap central bore; The impeller post is in urceolus, and an end of impeller post has second bearing between impeller post and the end cap in end cap central bore; Described impeller post has cylindrical bar, on the outer wall of cylindrical bar, helical blade is arranged; The other end screw thread of urceolus is fixed with gland, and the other end of impeller post passes the gland centre bore, and between gland and the impeller post clutch shaft bearing is arranged; The other end of impeller post has one section centre bore, on the impeller post transverse holes is arranged, and transverse holes is communicated with the annular space that impeller post centre bore and impeller post and urceolus are formed; When steam gets into and promote the helical blade of impeller post from the steam channel of end cap, the impeller post can rotate.The cutter head of a circle is arranged on the end face of impeller post centre bore, and cutter head has centre bore, and the cutter head locking handle passes the centre bore of cutter head, and the threaded one end of cutter head locking handle is fixed on the end of impeller post, and the cutter head locking handle compresses cutter head; Described cutter head locking handle has centre bore.
In order to improve sealing, between urceolus and gland, sealing ring is arranged.
Described cutter head is made up of doughnut-shaped steel plate and blade, and blade is a rectangular flat plate, and four blades are vertically fixed on the outer edge of doughnut-shaped steel plate, and the outer that cutter head rotates back four blades forms a cylinder bodily form.
The beneficial effect of the utility model: the utility model tube inner wall rotary cleaning device is a power with steam, and the rotation of drives impeller post is rotated thereby drive cutter head, through heat energy cutting oil inside pipe wall, reaches the purpose of cleaning oil pipe; Steam stings out from the manhole of cutter head locking handle, thorn washing oil inside pipe wall and cutter head, guaranteed cutter head cleaning and can be not stuck in oil pipe; Under the double action of cutter head and steam,, quick, easy with the paraffin of tube inner wall, the cutting of former wet goods knot shape, thorn wash clean; Because this device has certain length and external diameter to equate with the jack rabbit external diameter; In cutting, thorn washing oil inside pipe wall, the effect of also having served as jack rabbit is when having reduced latus rectum; Because of the probability that tubing bending can not normally pass through, need not mention oil pipe when can't pass and come the taking-up instrument.
