Electronic Cartridge for Downhole Probes | Specifications & Verification

Product Specifications

Technical details and manufacturing context for Electronic Cartridge

Definition

The Electronic Cartridge is a critical component of a Downhole Probe (Survey Tool) designed for oil and gas well logging. It houses the core electronic systems responsible for measuring downhole parameters (e.g., pressure, temperature, gamma radiation), processing the sensor data, and transmitting it to surface equipment via telemetry. It is engineered to withstand extreme downhole environments, including high pressure, high temperature, and vibration.

This cartridge integrates sensors that convert physical parameters into electrical signals, which are then conditioned, digitized, and processed by onboard microprocessors. The processed data is formatted and transmitted uphole via a wired or wireless telemetry system integrated within the downhole tool string. The housing is typically made of stainless steel (316L) for corrosion resistance, with ceramic insulators, silicon semiconductors, and high-temperature epoxy for encapsulation.

Key parameters include an operating pressure of 1.0–1.6 MPa, operating temperature range of -40 to 85 °C, supply voltage of 9–36 V DC, power consumption of 0.5–2.0 W, data rate of 10–100 kbps (UART or CAN), sampling rate of 1–100 Hz, measurement accuracy of ±0.1% FS, ingress protection IP68 (IEC 60529), shock resistance of 1000 g (IEC 60068-2-27), vibration resistance of 20 g RMS (IEC 60068-2-6), and dimensions of Ø25×120 mm. Weight ranges from 0.5 to 1.5 kg depending on connector type.

These values are reference ranges and must be verified with the legal manufacturer or supplier for the specific model and application. The cartridge is a component, not a standalone product, and its performance depends on integration with the downhole tool. Always confirm model-specific specifications and standards compliance before procurement.

Working Principle

The cartridge contains sensors that convert physical downhole parameters into electrical signals. These signals are conditioned, digitized, and processed by onboard microprocessors. The processed data is then formatted and transmitted uphole via a wired or wireless telemetry system integrated within the downhole tool string. The system is designed to operate reliably under high pressure, high temperature, and vibration, with protective encapsulation and robust housing.

Frequently Asked Questions

What is the operating pressure range of the Electronic Cartridge?

The reference operating pressure range is 1.0–1.6 MPa. However, this is a directory reference; the actual range for a specific model must be confirmed with the manufacturer or supplier.

What communication interfaces does the cartridge support?

The cartridge supports UART or CAN interfaces with a data rate of 10–100 kbps. The exact interface and protocol should be verified with the manufacturer for the specific model.

What is the ingress protection rating?

The cartridge is rated IP68 per IEC 60529, indicating it is sealed against dust and prolonged immersion. This rating is a reference and should be verified for the specific model.

Can the cartridge withstand high shock and vibration?

The reference shock resistance is 1000 g (half-sine 1 ms) per IEC 60068-2-27, and vibration resistance is 20 g RMS (5–500 Hz) per IEC 60068-2-6. These values are indicative and must be confirmed for the actual model.
