★ Technical parameters(four parameters)
→ Temperature test :0-350 ℃ Accuracy: 1%
→ Pressure Test :0-35MPa Accuracy: 0.1%
→ Flow Test :0-200r / s Accuracy: 3%
→ Dryness test :0-90% Accuracy: 5%
★ Application
→Steam absorption profile test for high temperature steam injection wells;
→Wellbore heat loss test for high temperature steam injection wells;
★ Principle of flow part
When the instrument go through the insulating tube (φ62), the centralizer and collecting umbrella are closed. Centralizer controls collecting umbrella open. When the instrument reaches the test section – oil layer casing (φ160), the centralizer is open, as well as collecting umbrella.The fluid is forced to flow into flowmeter under the control of collecting umbrella, then the high-temperature steam entirely adhere to the meter,which improves steam flow measurement accuracy.
★ Feature
Structure:centralizer +collecting umbrella + turbine flowmeter
5-10 times higher resolution of steam absorption cross section
