The YLхх-4602 Series electronic downhole memory gauge belongs to the high-precision electronic pressure gauge. The gauge adapts the silicon-sapphire sensor and is easy to operate and maintain, allowing you to log various kinds of gas well, oil well and water well under high temperature and pressure environment with high sensitivity and data-acquisition precision. The “xx” stands for the external diameter of the gauge.
Applications
Pressure Build-up & Drawdown Tests
Uniform or Non-uniform Production Tests
Interference/Pulse Tests & Limit Tests
Static Pressure, Flowing Pressure & Pressure Gradients
Formation Damage Evaluation Tests
