Abstract

The invention relates to the technical field of oil production engineering, belongs to a coating type curable proppant friction test device used in the field of oil field fracturing, and is used for mainly solving the problem that conventional testing methods cannot meet testing requirements of coating type curable proppants. The coating type curable proppant friction test device comprises a base plate (1), a precise proportion spring (2), a guide feed rod (3), a linear bearing (4), a proportion spring pre-compression limit stop (5), a forward screw (6), forward and reverse differential nuts (7), a reverse screw (8), a standard friction head (9), a sample mounting plate (10), a rolling ball guide rail slide block (11), a rolling ball guide rail (12) and a load meter (13); the base plate (1) and the guide feed rod (3) are fixedly connected; the forward screw (6) and the reverse screw (8) are fixed with the forward and reverse differential nuts (7) in a screw thread manner; the standard friction head (9) is in bolted connection with the linear bearing (4); the sample mounting plate (10) is in bolted connection with the rolling ball guide rail slide block (11). The coating type curable proppant friction test device can simulate loss situations after caking and friction of a coating type curable proppant and has the advantages of easy opening, easy cleaning, simple and convenient operation and the like.

Description

technical field [0001] The invention relates to the technical field of oil production engineering, and belongs to a coating type curable proppant friction test device used in the field of oil field fracturing. Background technique [0002] In the field of oilfield fracturing, in order to ensure the effect of fracturing, it is necessary to conduct evaluation experiments on fracturing proppants. The friction rate test is to simulate the surface coating, the inner wall of the tubing and the formation after the coating-type curable proppant is cured, and evaluate the anti-friction degree of the coating-type curable proppant coating material. There is no corresponding test device at present, so a friction test device was developed, which can be used to simulate the friction of the surface coating of the test block under a certain pressure during the reciprocating motion after the coating curable proppant is consolidated. Contents of the invention [0003] The purpose of the pr...
