Abstract
An oil well paraffin scraper is characterized in that a connector is rigidly connected with an adapter, the adapter is rigidly connected with a scraper part, and the scraper part is connected with a scraper by a supporting body connected with the adapter. After the oil well paraffin scraper of the utility model descends to a preset depth and an opening is opened in the paraffin in the area by the scraper, the oil well paraffin scraper can be driven to rotate by the rotary driving device, so that the paraffin adhered on the inner wall of the oil pipe is removed along the circumferential direction of the oil pipe, and the problems that the conventional paraffin scraper blocks a scraping edge during paraffin scraping and reduces paraffin scraping efficiency are solved.
Description
Technical Field
The utility model relates to the technology of oil well operation equipment, in particular to an oil well paraffin scraper.
Background
In oil field development, if the oil well cannot self-blow, oil extraction must be performed by mechanical energy, so-called secondary oil extraction. In domestic and foreign petroleum production wells, mechanical oil production wells generally account for more than 80%, and a deep well pump device of a beam pumping unit is widely used for mechanical oil production. The sucker rod is connected with the piston and is put into the pump cylinder, and the piston is provided with a discharge valve. The uppermost surface of the pumping rod is connected with a polish rod which is hung on the horsehead of the pumping unit and moves up and down in a reciprocating manner, so that a piston of the deep well pump is driven to pump oil. The underground crude oil contains paraffin, and is deep in an oil well, high in temperature and pressure, high in dissolved gas in petroleum, strong in wax dissolving force and free from precipitation. From a certain depth position in the well, the oil flow temperature and pressure are reduced, so that the wax dissolving capacity of the oil is reduced, the wax in the oil is precipitated and adhered to the inner wall of the well pipe and the sucker rod, the more the wax is bound, the smaller the section of the oil passing space of the well pipe is, the oil flow is influenced, and the oil output is reduced. For normal oil production, the well pipe must be cleaned of paraffin. The higher the wax content of crude oil, the more serious the wax deposition of the oil well, and the more frequent the wax removal operation, for example, the area with 15 to 5 percent of wax content is removed once in two to three days, and even the area needs to be removed twice a day.
The accumulated paraffin removal adhered to the sucker rod on the wall of the oil well pipe is removed by thermal paraffin removal, mechanical paraffin removal and other methods. The thermal paraffin removal comprises hot oil circulation paraffin removal, electric heating paraffin removal and the like, but the energy consumption is high and the cost is high; the mechanical paraffin removal adopts winch paraffin scraping sheets, nylon paraffin scraping blocks and the like, has limited use effect, is not popularized and used, and has to remove paraffin in a well pipe in order to be capable of normally extracting oil.
Disclosure of Invention
In order to overcome the defects in the prior art, the utility model aims to provide the oil well paraffin scraper, which solves the problems that the conventional paraffin scraper blocks a scraping edge when scraping paraffin and reduces paraffin scraping efficiency.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
the utility model provides an oil well wax scraper, includes joint (1), its characterized in that connects (1) rigid connection adapter (2), and adapter (2) rigid connection scraper part (3), scraper part (3) are connected scraper (5) by supporter (4) that adapter (2) connect.
The scrapers (5) are distributed at different angles, and the number of the scrapers is not limited.
The scrapers (5) are distributed at 90 degrees, and the number of the scrapers is 4.
The two ends of the scraper (5) are slightly tilted upwards.
The beneficial effects of the utility model are as follows:
this structure can effectually scrape wax, and under the condition that one scrape the mouth and have the jam, other scrape mouthful still can work.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Fig. 2 is a partial cross-sectional view of a doctor blade of the utility model.
Description of the embodiments
The utility model will be further described with reference to the accompanying drawings and the working principle.
As shown in fig. 1, the oil well paraffin scraper comprises a connector (1), and is characterized in that the connector (1) is rigidly connected with an adapter (2), the adapter (2) is rigidly connected with a scraper part (3), and the scraper part (3) is connected with a scraper (5) through a supporting body (4) connected with the adapter (2).
The scrapers (5) are distributed at different angles, and the number of the scrapers is not limited.
The scrapers (5) are distributed at 90 degrees, and the number of the scrapers is 4.
The two ends of the scraper (5) are slightly tilted upwards.
The working principle of the utility model is as follows:
after the oil well paraffin scraper of the utility model is descended to a preset depth and an opening is opened in the paraffin in the area by the scraper, the oil well paraffin scraper can be driven to rotate by the rotary driving device, so that the paraffin adhered on the inner wall of the oil pipe is removed along the circumferential direction of the oil pipe. The plurality of groups of scrapers can prevent that gaps among one group of scrapers cannot work after being blocked.
The rotation driving device may specifically include: the driving motor and the transmission device can be in transmission connection with the connector and can drive the oil well paraffin scraper to synchronously rotate. The specific structure of the transmission device is not particularly limited in this embodiment, and only the rotational motion output by the driving motor can be transmitted to the oil well paraffin scraper.
Claims (4)
1. The utility model provides an oil well wax scraper, includes joint (1), its characterized in that connects (1) rigid connection adapter (2), and adapter (2) rigid connection scraper part (3), scraper part (3) are connected scraper (5) by supporter (4) that adapter (2) connect.
2. An oil well wax scraper according to claim 1, characterized in that the scrapers (5) are arranged at different angles, the number of which is not limited.
