Description

The curable proppant friction test device of one kind coating class
Technical field
The present invention relates to technical field of oil production engineering, belongs to a kind of curable of class of coating used in oil field compression fracture field Support agent friction test device.
Background technology
In oil field compression fracture field, to guarantee pressing crack construction effect, evaluation experimental need to be done to fracturing propping agents.Friction rate is tested After being the curable proppant solidification of simulation coating class, between face coat and tube inner wall, stratum, curable of class of coating is evaluated Support agent coating material friction resistant degree.Currently without corresponding assay device, therefore a kind of friction test device is have developed, it can be with Friction feelings during test block surface coating is moved back and forth under pressure after for simulating the curable proppant consolidation of coating class Condition.
The content of the invention
It is an object of the invention to provide can coat the curable proppant of class and consolidate under the conditions of laboratory simulation certain pressure The curable proppant friction test device of a kind of coating class of friction condition of the test block in reciprocating motion after knot.
The technical scheme is that:It is by soleplate, accurate proportional spring, guiding feed rod, linear bearing, proportional spring Precommpression limiting block, positive screw rod, forward and reverse differential nut, counterscrew, standard friction head, sample installing plate, spherical guide Slide block, spherical guide and loadmeter composition;Wherein soleplate is fixedly connected with feed rod is oriented to, accurate proportional spring by soleplate and Linear bearing is fixed, and is oriented to feed rod and is slidably connected with linear bearing, is oriented to feed rod and is connected with proportional spring precommpression limiting block bolt Connect, positive screw rod and counterscrew are fixed with forward and reverse differential nut's screw thread, standard friction head and linear bearing bolt connection, examination Sample installing plate and spherical guide slide block bolt connection, spherical guide slide block is slidably connected with spherical guide, and spherical guide is fixed on On soleplate, loadmeter be oriented to feed rod, linear bearing bolt connection.
Soleplate, accurate proportional spring, be oriented to feed rod, linear bearing, proportional spring precommpression limiting block, positive screw rod, Forward and reverse differential nut, counterscrew, sample installing plate, spherical guide slide block, spherical guide adopt T10 carbon tool steels, mark Quasi-friction head adopts the low-alloy super-strength steels of AISI 4340.
The present invention has the advantages that:
The present invention does standard friction head using the low-alloy super-strength steels of AISI 4340 so that the device can be born because reciprocal The high temperature that motion is produced, and have higher wear resistence.Simultaneously eccentric rotating disk, connecting rod are done from 4A01 aluminum alloy materials, because of material Can gentlier reduce and move back and forth the loss for producing.It is forward and reverse differential nut, makes sample installing plate using T10 carbon tool steel It is more accurate when downward pressure is controlled, and install convenient and swift during test block, the device can simulate maximum strata pressure 50MPa。
Description of the drawings:Fig. 1 is the structural representation of the present invention.
Specific embodiment:Below in conjunction with accompanying drawing, the invention will be further described, and it is by soleplate 1, accurate ratio bullet Spring 2, it is oriented to feed rod 3, linear bearing 4, proportional spring precommpression limiting block 5, positive screw rod 6, forward and reverse differential nut 7, reversely Screw rod 8, standard friction head 9, sample installing plate 10, spherical guide slide block 11, spherical guide 12 and loadmeter 13 are constituted;Wherein base Plinth plate 1 be oriented to feed rod 3 be fixedly connected, accurate proportional spring 2 is fixed by soleplate 1 and linear bearing 4, be oriented to feed rod 3 with it is straight Bobbin holds 4 and is slidably connected, and is oriented to feed rod 3 and the bolt connection of proportional spring precommpression limiting block 5, positive screw rod 6 and counterscrew 8 Fix with the screw thread of forward and reverse differential nut 7, standard friction head 9 and the bolt connection of linear bearing 4, sample installing plate 10 is led with ball The bolt connection of rail slide block 11, spherical guide slide block 11 is slidably connected with spherical guide 12, and spherical guide 12 is fixed on soleplate 1 On, loadmeter 13 be oriented to feed rod 3, the bolt connection of linear bearing 4.
Soleplate 1, accurate proportional spring 2, guiding feed rod 3, linear bearing 4, proportional spring precommpression limiting block 5, forward direction Screw rod 6, forward and reverse differential nut 7, counterscrew 8, sample installing plate 10, spherical guide slide block 11, spherical guide 12 adopt T10 Carbon tool steel, standard friction head 9 adopts the low-alloy super-strength steels of AISI 4340.
When laboratory is used, first sample is fixed on sample installing plate 10, after sample is installed, adjusts forward and reverse differential spiral shell Female 7 make standard friction head 9 contact with test block.Continue the forward and reverse differential nut 7 of adjustment makes accurate proportional spring by linear bearing 4 2 produce compression, and the pointer of loadmeter 13 starts finger and moves, and the forward and reverse differential nut 7 of regulation reaches the pressure value required for test, tests Afterwards, forward and reverse differential nut 7 is adjusted, loosens accurate proportional spring 2, the straight limit bearing of proportional spring precommpression limiting block 5 4, under certain clossing pressure, the oscillation cycle number of experiment is recorded, weigh the difference of weight after the weight before test and test Percentage rate be wear rate.
