in preceding method, described displacement measurement wheel is uniformly distributed with one group of magnet pair along the circumference, the polarity cross-distribution that one group of magnet is right, by being located at the alternately change frequency n of the hall device identification magnet polarities of displacement measurement wheel side, thus draw the number of turns that wheel rotates forward or backwards, and calculate the displacement L of flexible rod as follows:
L=2（R+r）nπ÷z
in formula: R is the radius of displacement measurement wheel,
r is the radius of flexible rod,
n is the alternately change frequency of magnet polarities,
z is that magnet is to quantity.
according to of the present invention a kind of bailing formula oil pumper displacement tester that said method is formed be, this device comprises derrick panel, derrick panel one end is provided with large pulley, on large pulley, cover has flexible rod, flexible rod one end is connected with down-hole relevant device, and the flexible rod other end and reel are intertwined and connected; Described derrick panel is provided with mounting bracket, and mounting bracket end face is provided with displacement measurement wheel, and displacement measurement wheel both sides are respectively equipped with contact roller; Displacement measurement wheel is positioned to roll below flexible rod and with flexible rod and is connected, and contact roller is positioned to roll above flexible rod and with flexible rod and is connected.
in aforementioned means, the outer rim of described displacement measurement wheel is uniformly distributed with one group of magnet pair along the circumference, the polarity cross-distribution that one group of magnet is right; Displacement measurement wheel side is provided with hall device.
in aforementioned means, described displacement measurement wheel is connected with mounting bracket end face with contact roller, the race peak that the race minimum point of contact roller is taken turns lower than displacement measurement.
in aforementioned means, the axis being parallel of described mounting bracket end face and flexible rod.
owing to have employed technique scheme, compared with prior art, the present invention successfully solves because bailing formula oil pumper does not have polished rod eye cannot install the technical problem of displacement testing equipment, can facilitate the analysis of oil well condition in the present invention.The present invention without the need to changing existing bailing formula oil pumper, therefore can not produce any adverse effect to the work of existing bailing formula oil pumper to the improvement of bailing formula oil pumper.Only need to install a set of checkout gear on existing derrick panel, checkout gear is not by the impact of large pulley both sides flexible rod angle; Need not unclamp flexible rod two during installation, flexible rod only need be allowed to be in relaxed state can be clamp-oned flexible rod in the displacement measurement wheel of checkout gear and the race of contact roller, installs very convenient, can construct at the scene.Apparatus structure of the present invention is simple, and improvement cost is low.During if do not needed, only checkout gear need be removed, restorative good, can widely use on bailing formula oil pumper, there is dissemination.
