Abstract
The utility model discloses a kind of oil well failure judgment means, comprise connecting rod, connecting rod is connected successively with upper clasp, upper junction plate, mechanical type draw-bar donamometer, lower connecting plate and lower clasp, the latter half of lower clasp is bolted in linkage, the interior bottom of linkage is provided with polished rod side card, also comprise polished rod, the first half of polished rod is stuck in linkage inside by polished rod side card, and the latter half of polished rod is exposed to outside linkage.This device can be seen the situation of change of producing well load intuitively, thereby the reason of judgement oil well failure, does not need professional test personnel to carry tester and reaches the spot, and has reduced tester's labour intensity, shorten the processing time of oil well failure, guaranteed the oil recovery efficiency of oil well simultaneously.
Description
Technical field
The utility model belongs to oil field equipment technical field, is specifically related to a kind of oil well failure judgment means.
Background technology
Oil is one of most important energy in the world, be also many chemical industry products as chemical fertilizer, pesticide and plastics etc. raw material.Due to the important function of oil, oil exploration industry has also stepped into a peak in recent years.China is oil big country, and oil area is large, is recover petroleum, and the quantity of oil well is also more and more, but because the situation of down-hole cannot be predicted, so oil well can often break down.The method of existing judgement oil well failure is generally that professional test personnel carry tester and test to scene, but because the remote oil well of China is more, oil district road is complicated, to tester, bring a lot of inconvenience like this, in addition due to China tester shortage, tester can not reach the spot in time, will make like this processing time of oil well failure extend, and has reduced the tar productivity of oil well.
Utility model content
The purpose of this utility model is to provide a kind of oil well failure judgment means, and this device has shortened the processing time of oil well failure, has reduced tester's labour intensity.
The technical scheme that the utility model adopts is: a kind of oil well failure judgment means, comprise connecting rod, connecting rod is connected successively with upper clasp, upper junction plate, mechanical type draw-bar donamometer, lower connecting plate and lower clasp, the latter half of lower clasp is bolted in linkage, the interior bottom of linkage is provided with polished rod side card, also comprise polished rod, the first half of polished rod is stuck in linkage inside by polished rod side card, and the latter half of polished rod is exposed to outside linkage.
Feature of the present utility model is also:
Between connecting rod, upper clasp, upper junction plate, be by welding mode connect.
Between lower connecting plate and lower clasp, be by welding mode connect.
Linkage is tubular.
The range of mechanical type draw-bar donamometer is 0-120kN
The beneficial effects of the utility model are: a kind of oil well failure judgment means, can see intuitively the situation of change of producing well load, thereby the reason of judgement oil well failure, not needing professional test personnel to carry tester reaches the spot, reduced tester's labour intensity, shorten the processing time of oil well failure, guaranteed the oil recovery efficiency of oil well simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of oil well failure judgment means of the utility model;
Fig. 2 is the lateral view of a kind of oil well failure judgment means of the utility model.
In figure, 1. connecting rod, 2. goes up clasp, 3. upper junction plate, and 4. mechanical type draw-bar donamometer, 5. lower connecting plate, 6. plays clasp, 7. bolt, 8. linkage, 9. polished rod side card, 10. polished rod.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
A kind of oil well failure judgment means of the utility model, as depicted in figs. 1 and 2, comprise connecting rod 1, connecting rod 1 is connected successively with upper clasp 2, upper junction plate 3, mechanical type draw-bar donamometer 4, lower connecting plate 5 and lower clasp 6, the latter half of lower clasp 6 is fixed in the linkage 8 of tubular by bolt 7, the interior bottom of linkage 8 is provided with polished rod side card 9, also comprise polished rod 10, the first half of polished rod 10 is stuck in linkage 8 inside by polished rod side card 9, and the latter half of polished rod 10 is exposed to outside linkage 8.Between lower connecting plate 5 and lower clasp 6, be by welding mode connect,, the range of mechanical type draw-bar donamometer 4 is 0-120kN.
During use, first check whether connection is tight everywhere, then determine the length of polished rod 10, polished rod 10 is stretched in oil well, be connected with the beam hanger in well, start oil pumper, polished rod 10 is passed to mechanical type draw-bar donamometer 4 by the pulling force of beam hanger in oil well by linkage 8, by observing the digital situation of change of determining load on mechanical type draw-bar donamometer 4, finally according to load, judge the fault that oil well occurs.
Table 1 is oil well failure judgement table, and according to the load range in table, we can judge the fault that oil well occurs.
Table 1 oil well failure judgement table
A kind of oil well failure judgment means of the utility model, that mechanical draw-bar donamometer in this device has advantages of is easy to use, clear reading, stable performance and safe and reliable, tubular linkage has attractive in appearance, the advantage of safety, while normally working by load shown on mechanical type draw-bar donamometer and oil well, the difference of load judges the reason of oil well failure, this has not only saved and by oil-well test gauge, had judged the link of oil well failure in the past, can also reduce tester's workload, guarantee personal security, improved operating efficiency.
