Description
Technical field
the utility model relates to a kind of bailing formula oil pumper displacement tester, belongs to oilfield well testing device technique field.
Background technology
bailing formula oil pumper is a kind of novel oil pumper, have employed the displacement artificial lifting way different from traditional oil pumper.Bailing formula oil pumper adopts flexible rod to be connected with down-hole relevant device, and during upstroke, motor drives spool turns by transmission device, is wrapped on reel by flexible rod, thus drive plunger to move upward, and oil well pump is given rise to predetermined altitude.Motor reversion during down stroke, relies on the deadweight of the down-hole such as oil well pump, flexible rod relevant device to drop to the precalculated position of down-hole, completes an oil pumping circulation.A rear situation about recovering according to downhole crude that circulated of pumping, carries out next one oil pumping circulation after waiting for a period of time.Compared with traditional oil pumper, there is stroke large, the feature that the cycle of operation is long.But bailing formula oil pumper eliminates traditional polished rod eye, therefore traditional displacement measurement equipment cannot be installed.Because displacement testing equipment do not installed by bailing formula oil pumper, oil well condition analysis is very restricted.
Utility model content
the purpose of this utility model is, provides a kind of bailing formula oil pumper displacement tester, can not carry out the technical problem of oil well condition analysis, thus overcome the deficiencies in the prior art during to solve and to adopt the work of bailing formula oil pumper.
the technical solution of the utility model is achieved in that
a kind of bailing formula oil pumper displacement tester of the present utility model is, this device comprises derrick panel, and derrick panel one end is provided with large pulley, and 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 utility model successfully solves because bailing formula oil pumper does not have polished rod eye cannot install the technical problem of displacement testing equipment the utility model, can facilitate the analysis of oil well condition.The utility model 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 utility model 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.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model;
fig. 2 is the structural representation of displacement measurement wheel.
being labeled as in accompanying drawing: 1-derrick panel, 2-large pulley, 3-flexible rod, 4-mounting bracket, 5-displacement measurement is taken turns, 6-contact roller, 7-magnet pair, 8-hall device.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to any restriction of the present utility model.
Embodiment
the utility model is constructed by a kind of following method of installing displacement tester on bailing formula oil pumper, as shown in Figure 1, the method is on the derrick panel 1 of bailing formula oil pumper, fix a mounting bracket 4, mounting bracket 4 end face is parallel with flexible rod 3, then a displacement measurement wheel 5 is fixed at mounting bracket 4 end face, and in displacement testing wheel 5 both sides, contact roller 6 is installed, and flexible rod 3 is taken turns bottom 5 tops and contact roller 6 through being wrapped in the cylinder that is connected with motor (cylinder does not draw) from displacement measurement; Drive displacement measurement to take turns 5 by flexible rod 3 to rotate, record displacement testing wheel 5 rotates the displacement L that the number of turns calculates flexible rod.Displacement measurement wheel 5 is uniformly distributed with one group of magnet along the circumference as shown in Figure 2 to 7, one group of magnet to 7 polarity cross-distribution, the hall device 8 of taking turns 5 sides by being located at displacement measurement identifies the alternately change frequency n of magnet polarities, thus draw the number of turns that displacement measurement wheel 5 rotates forward or backwards, and calculate the displacement L of flexible rod 3 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 utility model a kind of bailing formula oil pumper displacement tester that said method is formed be, this device comprises derrick panel 1, derrick panel 1 one end is provided with large pulley 2, on large pulley 2, cover has flexible rod 3, flexible rod 3 one end is connected with down-hole relevant device, and flexible rod 3 other end and reel are intertwined and connected; Described derrick panel 1 is provided with mounting bracket 4, and mounting bracket 4 end face is provided with displacement measurement wheel 5, and displacement measurement is taken turns 5 both sides and is respectively equipped with contact roller 6; Displacement measurement wheel 5 is positioned to roll below flexible rod 3 and with flexible rod 3 and is connected, and contact roller 6 is positioned to roll above flexible rod 3 and with flexible rod 3 and is connected.Can increase by contact roller 6 contact length that flexible rod 3 and displacement measurement take turns 5 and increase frictional force, prevent flexible rod 3 and displacement measurement and take turns slip between 5, raising certainty of measurement.The outer rim of displacement measurement wheel 5 is uniformly distributed with one group of magnet along the circumference to 7, one group of magnet to 7 polarity cross-distribution; Displacement measurement wheel side is provided with hall device 8.Displacement measurement wheel 5 is connected with mounting bracket 4 end face with contact roller 6, and the race minimum point of contact roller 6 takes turns the race peak of 5 lower than displacement measurement.The axis being parallel of mounting bracket 4 end face and flexible rod 3.
