Abstract
The utility model discloses a ferromagnetic oil pipe thread protection device applied to oilfield operation sites. The ferromagnetic oil pipe thread protection device comprises a protecting sleeve, a magnet, an oil pipe and a sliding rail, wherein the protecting sleeve is of a cylindrical body; a cylindrical wall of the protective sleeve is provided with the magnet; a cylinder of the protecting sleeve is sleeved on a threaded end of the oil pipe; the magnet is abutted against the oil pipe; the sliding rail is installed on a well site; the protecting sleeve is located on the sliding rail; the magnet is in contact with the oil pipe; the protecting sleeve and the oil pipe are assembled into a whole by using the magnetic force; when sliding on the sliding rail, the protecting sleeve does not fall off the oil pipe, so that the oil pipe thread is protected all the time; when the oil pipe descends, the traditional contact between the oil pipe thread and the sliding rail is changed into the contact between the protecting sleeve and the sliding rail, so that the thread on the oil pipe is not worn down and the protecting sleeve and the sliding rail are not worn down. Thus, the ferromagnetic oil pipe thread protection device disclosed by the utility model can achieve design purpose, is convenient to use, does not increase labor intensity and influence work progress and is remarkable in economic benefits.
Description
Technical field
The utility model is the instrument of the on-the-spot usefulness of oil field operation, is a kind of strong magnetic tubing round thread protective device.
Background technology
During oil well operation well workover, oil pipe is tripped out horizontal rows in the well and place on ground, also will the oil pipe that horizontal rows is placed on ground be lowered in the oil well again, this two procedures all will make oil pipe from vertically becoming level or level becomes vertically.Oil pipe is being become the vertical process from vertically becoming level or level, and an end of oil pipe need slide on ground rail, and in sliding process, the screw thread of easy abrasion oil pipe and track cause the screw thread blow-by, cause that oil well is not fuel-displaced.For addressing this problem; The operation team that has at present adopts the oil pipe coaster between tubing round thread end and track; But this oil pipe coaster needs operating worker to back into the other end of track to it again from track one end after being drawn to the other end of track by the power of workover rig from track one end.Therefore, when this oil pipe coaster used at the scene, the operating worker workload was big, and labour intensity is high, and job scheduling is slow, thereby this oil pipe coaster seldom uses at the scene, and operating worker would rather the wear and tear screw thread and the track of oil pipe one end do not adopt this oil pipe coaster yet.
Summary of the invention
The objective of the invention is to design a kind of strong magnetic tubing round thread protective device, when an end of its oil pipe is slided on ground rail, the screw thread and the track of the oil pipe that do not wear and tear; Guarantee that tubing round thread can seal; And easy to use, do not increase labour intensity, do not influence job scheduling.
The purpose of the utility model is achieved in that and comprises that sheath, magnetic patch, oil pipe, slide rail, sheath are cylinder, install magnetic patch on the cylindrical wall of sheath; The cylinder of sheath entangles the end of thread of oil pipe; Magnetic patch leans against on the oil pipe, and slide rail is installed on the well site, and sheath is on the slide rail.
Sheath is nonmetals.
The beneficial effect of the utility model is: magnetic patch contacts with oil pipe, and magnetic force makes sheath and oil pipe be assembled into one, can not come off from oil pipe when on slide rail, sliding; Tubing round thread is protected all the time, and oil pipe is contacted with slide rail by the tubing round thread in past and to become sheath and contact with slide rail in the process of removing; Screw thread on the oil pipe can not liked wearing and tearing, can not wear and tear between sheath and the slide rail, therefore yet; The utility model can reach purpose of design, and is easy to use, do not increase labour intensity; Do not influence job scheduling, have remarkable economic efficiency.
Description of drawings
Fig. 1 is the installation drawing of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described.
Can know that by figure the embodiment of the utility model comprises sheath 1, magnetic patch 2, oil pipe 3, slide rail 4, sheath 1 is a cylinder; Magnetic patch 2 is installed on the cylindrical wall of sheath 1, and the cylinder of sheath 1 entangles the end of thread of oil pipe 3, and magnetic patch 2 leans against on the oil pipe 3; Magnetic patch 2 is a strong magnet; The magnetic force of magnetic patch 2 is combined into one sheath 1 and oil pipe 3, and slide rail 4 is installed on the well site, and sheath 1 is on the slide rail 4.During operation, sheath 1, magnetic patch 2, oil pipe 3 are 4 up of slide rails, and sheath 1 is nonmetals, and slide rail can not wear and tear when on slide rail 4, sliding.
Claims (2)
1. one kind strong magnetic tubing round thread protective device; Comprise sheath (1), magnetic patch (2), oil pipe (3), slide rail (4), it is characterized in that: sheath (1) is a cylinder, and magnetic patch (2) is installed on the cylindrical wall of sheath (1); The cylinder of sheath (1) entangles the end of thread of oil pipe (3); Magnetic patch (2) leans against on the oil pipe (3), and slide rail (4) is installed on the well site, and sheath (1) is on the slide rail (4).
