Introduction

It can be used to study scaling extent of water injection well and production well under downhole condition, which overcome the shortages of not evaluating scaling extent under downhole condition. The experimental data including temperature, pressure and flow rate can be acquired, calculated and plotted by computer.

Key Performance Indicators

1. operating temperature: ambient temperature～150℃;
2. operating pressure: 0～20MPa, 0～50MPa;
3. accuracy of pressure measurement: 0.25%;
4. core size: Φ25×25～100mm;
5. tester error: <5%.

Main Structure

1. dynamic displacement part, including two displacement pumps and intermediary containers;
2. pressure metering part at intake and output, including six-way valve travel and vernier gauge;
3. core holder controlled by temperature after being reformed;
4. casing pressure pump and flow metering part at output.
