The underground magnetic positioning device is characterized in that a shell (1) is connected below an upper connector (4); the shell (1) is internally provided with a coil (6) and an upper magnet (5) from bottom to top; the coil (6) is connected with a ground intelligent testing and controlling meter through a cable; a tester main body (2) is connected below the shell (1); a lower magnet (7) is connected below the tester main body (2); a centering device (3) is connected below the lower magnet (7); a weighted rod (8) is connected below the centering device (3). The underground magnetic positioning device of the steel pipe cable disclosed by the utility model has the characteristic of high positioning accuracy.
Description
Technical field
The utility model relates to the down-hole magnetic orientation device of oil-water well down-hole, oil recovery field, oil field used positioner, especially steel pipe cable.
Background technology
In the oilfield test technology, adopt positioner to obtain the magnetic orientation curve.And there is the low problem of setting accuracy in existing positioner owing to reasons in structure, and then influences testing efficiency and quality.
Summary of the invention
In order to solve the existing low problem of positioner setting accuracy.The utility model provides a kind of down-hole magnetic orientation device of steel pipe cable.The down-hole magnetic orientation device of this steel pipe cable has the high characteristics of setting accuracy.
The technical solution of the utility model is: the down-hole magnetic orientation device of this steel pipe cable comprises shell, tester main body, centralizer, top connection, goes up magnet, coil, lower magnet and weighted lever.Be connected with shell under the top connection, be equipped with coil and last magnet in the shell from the bottom to top successively, coil links to each other with the ground intelligent measurement and adjustment instrument by cable, be connected with the tester main body under the shell, be connected with lower magnet under the tester main body, be connected with centralizer under the lower magnet, be connected with weighted lever under the centralizer.
Centralizer in the such scheme comprises arc steel plate and around bar, and 3 above arc steel plate upper and lower sides are fixed in the last change and following change around bar.
The utlity model has following beneficial effect: the down-hole magnetic orientation device of this steel pipe cable is owing to be connected with shell under the employing top connection, be equipped with coil and last magnet in the shell from the bottom to top successively, coil links to each other with the ground intelligent measurement and adjustment instrument by cable, be connected with the tester main body under the shell, be connected with lower magnet under the tester main body, be connected with centralizer under the lower magnet, be connected with the structure of weighted lever under the centralizer.Utilize magnet and coil to constitute a complete magnetic field environment, when trade pipe thickness changed on the down-hole magnetic orientation device of this steel pipe cable, the magnetic line of force that is cut changed, thereby produced different curve ripples, thereby improved setting accuracy.The down-hole magnetic orientation device of this steel pipe cable has the high characteristics of setting accuracy thus.
