Abstract
The utility model relates to a scale scraping device of an oil pipe, which comprises a main body, a safe pin, a sliding sleeve, a right scraping piece, a left scraping piece and a shaft pin, wherein the main body is formed with a through slot, the slot is internally provided with the right scraping piece and the left scraping piece, the pin shaft passes through the right scraping piece and the left scraping piece, the pin shaft is fixed on the main body, the sliding sleeve is sleeved outside the main body, the sliding sleeve is fixed on the main body through the safe pin, the sliding sleeve is formed with a window, the right scraping piece and the left scraping piece are aligned to the window of the sliding sleeve, the right scraping piece and the left scraping piece are protruded out of the sliding sleeve, the lower end surfaces of the right scraping piece and the left scraping piece are propped against the lower end surface of the window of the sliding sleeve, the upper end of the main body is provided with a thread, the lower end of the main body is provided with a cone body, the right scraping piece and the left scraping piece can rotate around the pin shaft, the right scraping piece and the left scraping piece are reduced in the main body when downwards entering along the main body, thus the right scraping piece and the left scraping piece can smoothly enter the oil pipe, and when the main body is lifted up, the right scraping piece and the left scraping piece are unfolded to be contacted with the dirty layer of the inner wall of the oil pipe. Thus, the utility model can be used in the production of the oil pipe without shutting down, and has obvious economic benefit.
Description
Technical field
The utility model is the oil pipe prosthetic device that oilfield oil well is used, and is a kind of oil pipe scraper device.
Background technology
The oil pipe ubiquity scale problems that oilfield oil well is used makes the oil pipe aperture reduce after the fouling, can not be lowered to the instrument of production usefulness, influences oil-water well production, after the dirt piece comes off, also can cause dirt to bury oil pipe, blocking channel, block the tool of production, oil-water well is difficult to resume production, and produces heavy economic losses.The method of scale removal at present has chemical method and physics method, and chemical method adopts chemical medicine Ji and dirt reaction scale removal, but because dirt is many at composition, and the different regions dirt is different at composition, is difficult to effective scale removal.The scale removal of physics method is the oil pipe pendulum to be led to brill with drilling tool to oil pipe on ground realize scale removal, therefore, oil pipe must be tripped out the ability scale removal in well, can not scale removal in the oil pipe manufacturing process, so all there are certain limitation in chemical method scale removal and the scale removal of physics method, can not satisfy the field produces requirement.
Summary of the invention
The purpose of this utility model is a kind of oil pipe scraper device of design, makes it can scale removal in the oil pipe manufacturing process, and oil pipe does not stop production, and eliminates the influence of fouling to producing.
The purpose of this utility model is achieved in that by main body, safety pin, sliding sleeve, right scraping blade, left side scraping blade, bearing pin is formed, have groove on the main body, right scraping blade is installed in the groove, left side scraping blade, bearing pin passes right scraping blade, left side scraping blade, bearing pin is fixed on the main body, sliding sleeve is sleeved on outside the main body, sliding sleeve is fixed on the main body by safety pin, window is arranged on the sliding sleeve, right scraping blade, left side scraping blade is aimed at the window on the sliding sleeve, right scraping blade, the outstanding sliding sleeve of left side scraping blade, right scraping blade, scraping blade lower surface, a left side leans against on the lower surface of the window on the sliding sleeve, there is screw thread the main body upper end, and there is cone the main body lower end.
The beneficial effects of the utility model are: right scraping blade, left scraping blade can rotate around bearing pin, right scraping blade, left scraping blade are with fashionable being contracted in the main body under the main body, therefore, right scraping blade, left scraping blade can be lowered in the oil pipe smoothly, on when putting forward main body, right scraping blade, left scraping blade are stretched out the dirt that contact with tube inner wall on the scraping tube inner wall layer, therefore, the utility model can use in the oil pipe manufacturing process, and oil pipe does not stop production, and has remarkable economic efficiency.
Description of drawings
Accompanying drawing 1 is the assembling drawing of the utility model embodiment.
Accompanying drawing 2 is the profiles after cutting open from A-A in the accompanying drawing 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
As seen from the figure, embodiment of the present utility model is by main body 1, safety pin 2, sliding sleeve 3, right scraping blade 4, left side scraping blade 5, bearing pin 6 is formed, have groove on the main body 1, right scraping blade 4 is installed in the groove, left side scraping blade 5, bearing pin 6 passes right scraping blade 4, left side scraping blade 5, bearing pin 6 is fixed on the main body 1, sliding sleeve 3 is sleeved on outside the main body 1, and sliding sleeve 3 is fixed on the main body 1 by safety pin 2, on the sliding sleeve 3 window is arranged, right scraping blade 4, the window that left side scraping blade 5 is aimed on the sliding sleeve 3, right scraping blade 4, left side scraping blade 5 outstanding sliding sleeves 3, right scraping blade 4, scraping blade 5 lower surfaces, a left side lean against on the lower surface of the window on the sliding sleeve 3, and there is screw thread main body 1 upper end, there is cone main body 1 lower end, plays guiding function.
In order to scrape dirt on the full surface of tube inner wall, at the dirty sheet of scraping of wanting vertically to be provided with on the main body 1 the right scraping blade 4 of many groups, left scraping blade 5, operated by rotary motion 6 fine horses, each organizes the setting of evenly staggering, if group, each group staggers 30 °.The course of work of each group is identical.
