Abstract

A device for evaluating gel properties includes a left liquid inlet bottle and a right liquid inlet bottle, and a liquid inlet is connected with the left liquid inlet bottle; the left liquid inlet bottle is internally provided with a pump; the left liquid inlet bottle is connected with a nitrogen gas cylinder; a microscope is arranged between the left liquid inlet bottle and the right liquid inlet bottle, and an industrial camera is arranged above the microscope; the industrial camera is connected with a computer; a capillary is placed between a first pneumatic valve and a second pneumatic valve; a light source is arranged below the microscope; a rotating shaft is arranged between the left liquid inlet bottle and the right liquid inlet bottle and is provided with a rotary gear, and the rotating shaft is connected with a motor in the left liquid inlet bottle; the motor is connected with a speed regulating valve on the side wall of the left liquid inlet bottle; a liquid outlet is formed in the lower part of the left side wall of the right liquid inlet bottle. Evaluation comprises the steps: 1) preparing gel, and setting parameters; 2) opening the nitrogen gas cylinder, switching on a power supply, and setting the pump speed; 3) arranging the gel on the rotary gear, to obtain a gel image; 4) capturing the image; and 5) treating image data by software to obtain evaluation parameters.

Description

technical field [0001] The invention belongs to the technical field of gel mechanics evaluation, and in particular relates to a device for evaluating gel performance and an evaluation method thereof. Background technique [0002] Oil well water production is a common phenomenon encountered in the middle and late stages of oilfield development. In view of thick and numerous oil layers, large differences between layers, and high water content, it is necessary to control the layers with serious water production. Gel has become more and more widely used in chemical water plugging. application. At present, the general gel performance testing methods mainly include: core test method, viscoelasticity meter, texture analyzer, test tube method, etc. The existing gel performance detection method requires a lot of manual time to detect related parameters, and the cycle is long; due to the use of different instruments, the error is large. Contents of the invention [0003] In order ...
