Fracturing fluid friction tester

1、 Overview:

Fracturing fluid friction testerIt is used to test the fluid flow in pipelinesParameters such as pressure drop, friction gradient, shear rate, shear stress, fluid dynamic viscosity, etc，Simulate using the principle of similarity with on-site oil pipe and pump injection parametersThis is used to simulate the flow state of liquids during on-site construction, determine pipeline friction, and thus determine the quality of drag reducing agents.

Measure the friction between clean water and different fracturing fluids at different shear rates through pipelines, and obtain the ratio of the friction between clean water and different fracturing fluids at different shear ratesB.

At the same time, corresponding curve graphs can be drawn based on the computer acquisition system.

To evaluate the friction reduction performance of fracturing fluid, further understand the variation laws of friction with different fracturing fluids, different displacements, and different well depths, and provide a basis for optimizing fracturing fluid selection and fracturing optimization, this pipeline friction meter has the following functions:

1Can correspond to simulated on-site construction displacement;

2The experimental liquid includes clear water, base liquid, and drag reducer, and can be used for experiments with high liquid viscosity;

3、The equipment design scheme adopts a circulating circuit and uses multiple specifications of pipelines to simulate the flow of fracturing fluid in the pipeline on site;

2、 Characteristics:

1. Adopting advanced closed-loop process system for continuous testing;
2. Multiple test results can be obtained in one experiment, saving time and requiring less test liquid;
3. The experimental liquid circulates in a straight line in the pipeline, and the liquid structure will not be damaged;
4. Install over temperature and over pressure alarm and shutdown devices on the test pipeline to ensure safe testing;
5 High precision differential pressure transmitters, pressure sensors, electronic flow meters, precision temperature controllers, etc. are used for parameter measurement and control to ensure reliable test results;

3、 Function:

1、Measure the friction of clean water with different displacements to compare with the friction of the test liquid and provide a basis for construction design.
2、Measure the friction resistance of oil test liquids and evaluate oil resistance reducers.
3、The data collection and processing are all automatically completed by the computer, making the operation easy and effortless.
