Abstract
The utility model discloses an oil tube scraper for steel wire operation, which is applied to scraping the residual sundries on the inner wall of a downhole oil tube in an oil field. The oil tube scraper mainly consists of a fishing neck, a scraping body and scraping teeth. The fishing neck is arranged at the upper end of the cylindrical scraping body. The scraping teeth are uniformly distributed on the outer wall of the scraping body. Scraping slots are arranged between the scraping teeth. The oil tube scraper for steel wire operation has the effects that the scraper can clean the sundries which are residual on the wall of the downhole oil tube and hinder the construction operation; and the scraping body is cast by an integrated steel body, so that the oil tube scraper is firm to operate, and the safety problem of running tools is effectively solved. The scraping body is designed into the cone structure and is convenient for the running oil tube to operate.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly the down-hole oil tube inwall is scraped residual foreign material, is a kind of oil pipe scraper that is applicable to steel wire operation.
Background technology
At present, oil well has the residual foreign material of one deck at tube inner wall after recovering the oil through the long period, and as wax deposition, influence is normally recovered the oil.Conventional injection well tubing scraper and the oil pipe scraper that is loaded with drive motors of adopting in oil field carries out the oil pipe scraping.The injection well tubing scraper comprises scrapes bits main body, skiving blade, spheroid ball seat and pin.Scraping the bits main body is the skiving blade that tubulose and bottom have bell mouth shape, and scraping in the bits main body has ball seat by dowel fixes, and the ball seat end coincide and touched spheroid mutually.The shortcoming of injection well tubing scraper is that scraping is thorough inadequately, and consumable accessory is many.The oil pipe scraper that is loaded with drive motors comprises rope socket and scraping main body, and dynamic driving tube is equipped with drive motors in the power drive tube between rope socket and scraping main body, and drive motors is connected with the scraping main body, and the scraping main body is to have the spiral fluted cone.The advantage of this scraper is not need to rely on external force, and can be self-powered, relies on from the dynamic scraping main body that drives to rotate, and tube inner wall is cleaned.But shortcoming is complex structure, complicated operation, continuous operation ability in the scraper use.
The utility model content
The purpose of this utility model is: a kind of oil pipe scraper that is used for steel wire operation is provided, is suspended on the steel wire lower end, the handling operation repeatedly in the down-hole is removed and is remained in the foreign material that hinder construction operation on the downhole oil tube wall.Scraping is thorough, operates simple and easyly, makes in the oil pipe construction operation safer.
The technical solution adopted in the utility model is: be used for the oil pipe scraper of steel wire operation, mainly be made up of fishing neck, scraping body and scraping tooth, it is characterized in that: there is fishing neck the upper end at cylinder bodily form scraping body; On the outer wall of scraping body, be evenly distributed with the scraping tooth.The scraping groove is arranged between the scraping tooth.
Described scraping tooth is a cuboid, is distributed with 3～8 rows on the outer wall of scraping body, 4～6 row scraping teeth; And the position of two adjacent row's scraping teeth is staggered.
The external surface of described scraping body is that the arc diameter of scraping tooth on circular arc and top is greater than the arc diameter of the scraping tooth of bottom.It is conical to be that scraping tooth on the external wall of scraping is.
Described fishing neck, scraping body and scraping tooth are cast as one.
In carrying out oil pipe scraping process, whole paraffin scraper is subjected to steel wire traction, and tube inner wall is carried out scraping.The scraping repeatedly of scraping tooth is removed and is remained in the foreign material that hinder construction operation on the downhole oil tube wall.The scraping groove is the passage of liquid communication, and liquid can pass through in the scraping groove in the well.Conical paraffin scraper is up big and down small, is convenient to connect the steel wire operation instrument and is lowered to oil pipe, effectively avoids down fashionable chance card.
The beneficial effects of the utility model: the utility model is used for the oil pipe scraper of steel wire operation, can remove and remain in the foreign material that hinder construction operation on the downhole oil tube wall, the scraping body adopts incorporate steel body casting, make the operation of oil pipe scraper more firm, effectively solve the safety problem of the instrument that is lowered to.The scraping body adopts the cone structure design, is convenient to be lowered to oil pipe and carries out operation.
Description of drawings
Fig. 1 is the oil pipe scraper structural representation that the utility model is used for steel wire operation.
Among the figure, 1. fishing neck, 2. scraping body, 3. scraping tooth.
The specific embodiment
Embodiment 1: with an oil pipe scraper that is used for steel wire operation is example, and the utility model is described in further detail.
Consult Fig. 1.The utility model is used for the oil pipe scraper of steel wire operation, is made up of fishing neck 1, scraping body 2 and scraping tooth 3.Fishing neck 1, scraping body 2 and scraping tooth 3 are cast as one, are processed into then.
The external diameter of cylinder bodily form scraping body 2 is 40mm, and length is 194mm.There is an energy to be connected fishing neck 1 with steel wire in the upper end of scraping body 2; On the outer wall of scraping body 2, be evenly distributed with scraping tooth 3.
Scraping tooth 3 is a cuboid, distributes to have six rows, four lines scraping tooth 3 on the outer wall of scraping body 2; The positions of adjacent two row's scraping teeth 3 are staggered and the distance of 15mm, scraping groove between the two adjacent row scraping teeth 3 are arranged.
The external surface of scraping body 2 is that the greatest circle arc dia of the scraping tooth 3 on circular arc and top is 59mm, and the smallest circle arc dia of the scraping tooth 3 of bottom is 50mm.It is conical to be that scraping tooth 3 on scraping body 2 outer walls is.
