Abstract
The utility model belongs to the technical field of the test of the mechanics of machinery. An axial tension and pressure tester is designed for exactly and quantitatively measuring the stress value of an oil pumping rod post in the process of pumping oil and simultaneously can also measure any axial tensile load and pressure load. The utility model is mainly composed of an upper cover joint 1, a battery 2, an intelligent sensing memory 3, a signal wire 4, a strain gauge 5, a deformable body 8 and a lower joint 7, wherein, the strain gauge 5 is fixedly connected to the deformable body 6, and the intelligent sensing memory 3 is fixedly connected to the deformable body 6 by the signal wire 4 and the strain gauge 5. The axial tension and pressure tester is suitable for carrying out the axial tension and pressure test of all objects where tension and pressure are exerted in the axial direction. The utility model has the advantages of small size, light weight, easy operation, etc.
Description
Technical field: the utility model belongs to the Mechanics of Machinery technical field of measurement and test.
Background technology: oil pumper-ram pump is in oil pumping process, the rubbing action of friction force between plunger and the pump barrel and sucker rod string system, make sucker rod when upper and lower stroke, be subjected to the pressure effect, particularly behind the polymer injection of oil field, the effect of axial push-pull power alternate load, it is stressed complicated more that sucker rod is lived.How determining the stressing conditions of roofbolt in oil pumping process, so that take measures, overcome these load, prolong the serviceable life of sucker rod string, reduce the cost of oil extraction, is present problem extremely to be solved.Also there is not to determine the axial push-pull force tester of roofbolt stressing conditions in oil pumping process in the prior art.
Summary of the invention: the purpose of this utility model is in order accurately quantitatively to measure the stress value of sucker rod string in oil pumping process, can also measure any axial push-pull power load simultaneously and the axial push-pull force tester that designs.The utility model is made up of loam cake joint, battery, intelligent sensing memory, signal wire, foil gauge, deformable body, lower sub, wherein the screw thread screw thread identical with sucker rod of loam cake joint and lower sub.Loam cake joint and deformable body are screwed connections, foil gauge is fixedly connected on the deformable body, the intelligent sensing memory is fixedly connected on the deformable body, and link to each other with foil gauge by signal wire, lower sub and deformable body screwed connection, battery and intelligent sensing memory adopt pegs graft, and it has, and volume is little, in light weight, the characteristics of easy operating.
Description of drawings: Fig. 1 is the utility model apparatus subject structure diagram;
When Fig. 2 is this instrument test and the sucker rod connection diagram;
Fig. 3 unloads instrument replayed section figure after testing.
Embodiment: the utility model is made up of loam cake joint 1, battery 2, intelligent sensing memory 3, signal wire 4, foil gauge 5, deformable body 6, lower sub 7, wherein loam cake joint 1 screw thread identical with sucker rod with the screw thread of lower sub 7.Loam cake joint 1 and deformable body 6 are screwed connections, foil gauge 5 is fixedly connected on the deformable body 6, and intelligent sensing memory 3 is fixedly connected on the deformable body 6, and is linked to each other with foil gauge 5 by signal wire 4, lower sub 7 and deformable body 6 screwed connections, battery 2 and intelligent sensing memory 3 adopt pegs graft.
As long as during work this instrument is connected in the middle of two sucker rods, when sucker rod moves up and down when stressed foil gauge 5 along with deformable body 6 produces distortion, signal wire passes to intelligent sensing memory 3 with this distortion, and intelligent sensing memory 3 is just noted this stress value.When the roofbolt of a bite rod-pumped well needs multi-point sampler, this tester can be installed in the multiple spot position, just can one record sucker rod string 10 is subjected to pressure at the down-hole diverse location size and Orientation simultaneously.When end of test (EOT),, the proposition sucker rod carries out the stressing conditions that playback has just obtained roofbolt as long as linking to each other with lead 8 instrument with playback apparatus 9.
With the sucker rod test is example, as shown in Figure 3, at first the battery in the apparatus subject 2 is unloaded during test, connects playback apparatus 9 and testing tool main bodys with lead 8, by designing requirement tester is set, and has connected battery 2 then and loam cake joint 1 is standby.By the time lower sucker rod of setting, and instrument is connected in the position of designing requirement, under the sucker rod lower going-into-well, when sucker rod moved up and down, testing tool was started working.Test finishes and trips out sucker rod and unload instrument, instrument is linked to each other with playback apparatus 9 with lead 8 carry out the stressing conditions that playback has just obtained roofbolt.
