Embodiment Construction

[0021] Such as figure 1 Shown is one embodiment of the present disclosure. The power unit is driven by the motor cycloid pinwheel reducer 25 through the coupling 26, the transmission shaft 27, and the eccentric wheel 23 is driven to rotate, and the eccentric wheel 23 drives the connecting rod 21 through the crank pin 22 to perform plane movement (see figure 2 ). The other end of the connecting rod 21 is connected with a guide block connector 20 to make it move linearly on the guide rail 19 . The connecting rod 21 drives the pull bar 17 and the carrying slide 15 to reciprocate on the roller 12 through the slider pin 18 on the guide block connector 20 (see image 3 ). Wherein, guide rail 19 links to each other with support 49 by screw, and linear slide block 47 and support 46 are installed on the support 49, and is connected by screw, and connecting rod 21 links to each other with support 46 by bearing and bearing pin 44 (see Figure 6 ). Because the roller 12 sits on the ...

Abstract

The invention belongs to the technical field of friction and wear testing of petroleum machinery, in particular to a device for performing friction and wear tests of centralizers of various sizes by using a mechanical radial load application method. It is characterized in that: the power device (24) and the eccentric wheel (23) are connected with the connecting rod (21) through the crank pin (22), and the connecting rod (21) drives the pull rod (17) and the bearing slide plate (15) to roll The shaft (12) performs reciprocating motion, and the upper part of the bearing slide (15) is fixed with a half oil pipe (14); the centralizer (11) is fixed on the centralizer clamp (10), and the centralizer clamp (10) passes through the horizontal pin shaft ( 9) Connected with the support column (8), the support column (8) is guided by the guide sleeve (7), and the loading device (1) passes the load through the support column (8) and the centralizer clamp (10) through the loading lever (5) Add between centralizer (11) and half oil pipe (14). This scheme has a simple structure, is easy to operate, low in cost, easy to popularize, and can be equipped in a laboratory as a rapid evaluation means in the development process of the centralizer.

Description

technical field [0001] The invention belongs to the technical field of friction and wear testing of petroleum machinery, in particular to a device and method for performing friction and wear tests of centralizers of various sizes by applying a mechanical radial load application method and equipment. technical background [0002] As the major oilfields in eastern my country have successively entered the medium-high water-cut development period, oilfield exploitation is becoming more and more difficult. In order to improve oil recovery, polymer flooding technology has been rapidly developed in my country's oilfields in recent years. Practices over the past few years have shown that polymer flooding has achieved significant oil-increasing and water-increasing effects, but the non-Newtonian nature of the produced fluid causes severe eccentric wear of the sucker rod string and tubing, and the phenomenon of rod breakage increases significantly. Significantly shortened. In order t...
