Fracturing fluid proppant volume density tester

Abstract

The invention discloses a fracturing fluid proppant volume density tester. The tester comprises support pins, a baseplate, a sweeping plate, a sleeve, a first joint pin, a groove, a top plate, a hopper, a first discharge pipe, a rotating disc, a connecting bended lever, a second discharge pipe, a second joint pin, a neck, a testing bucket and discharge holes; the discharge holes in the first discharge pipe, the rotating disc and the second discharge pipe can be mutually aligned when the rotation of the rotating disc is realized through the mutual cooperation of the first discharge pipe, the rotating disc and the second discharge pipe, thereby realizing the internal communication of the hopper and the second discharge pipe, and the discharge speed of the hopper can be regulated by regulating the rotating disc; when the testing bucket is clamped into the neck, the testing bucket can be located just below the second discharge pipe; after the internal of the testing bucket is covered withthe proppant, the sweeping plate is rotated again; since the bottom end of the sweeping plate is aligned with an upper surface of the testing bucket, the sweeping plate can flatly sweep the proppant in the testing bucket and the tester is comparatively simple in the use.

Description

technical field [0001] The invention relates to a tester, in particular to a fracturing fluid proppant volume density tester, which belongs to the technical field of oil field chemicals. Background technique [0002] When the oil well production layer has low permeability or is seriously polluted by mud, it is necessary to carry out stimulation operations such as fracturing and acidification to improve the production capacity of oil and gas wells and the water absorption capacity of water injection wells; Water-based, oil-based, and acid-based fracturing fluids are selected according to reservoir conditions; river water was first used for fracturing fluids, and then thickened water was used for fracturing fluids, and gel has been developed to be used. Jelly fracturing fluid is made of thickened water with a thickener and further thickened with a crosslinking agent, which can improve the sand-carrying ability; the fracturing fluid contains enzymes and ammonium persulfate and ...

AI Technical Summary

Problems solved by technology

[0003] In oilfield work, the function of fracturing fluid is to fill the formation fractures with proppant and high-pressure solution into the formation, and play a role in supporting the fractures from closing due to stress release, so as to maintain high conductivity. To test it, the existing tester has a relatively simple structure, and the bottom of the hopper is generally sealed with a rubber ball, which is troublesome to use, difficult to control the feeding speed, and easily causes waste of resources
