Core Product Portfolio & Key Applications

Our product lineup is tailored to the specific needs of oilfield drilling, well logging, fluid management, and industrial control systems, with each component serving as a critical link in ensuring operational precision. Below is a structured breakdown of core products, their functions, and value propositions:

1. CPS-KQ-VI Series Pressure & Torque Sensors

The CPS-KQ-VI series is the backbone of our fluid pressure and torque measurement solutions, encompassing models for riser pressure, casing pressure, and suspension monitoring. These sensors are engineered to eliminate signal noise and drift, a common pain point in oilfield operations where fluctuating temperatures and mechanical vibration can compromise data integrity.

Function & Value

• Riser Pressure Sensor (SK-8Y34A/SK-8Y24A): Monitors downhole riser pressure in real time, with a measurement range of 0–100MPa and an accuracy of ±0.1% FS. Prevents overpressure risks that can lead to riser damage, a leading cause of non-productive time (NPT) in offshore drilling.

• Casing Pressure Sensor (SK-8Y36A): Tracks casing pressure during well completion, with a response time of <10ms to capture rapid pressure changes. Critical for maintaining wellbore stability and preventing casing collapse.

• Tongs Torque Sensor (SK-8N09/SK-8N10): Measures torque during drill pipe makeup and breakout, with a load capacity of up to 10,000 N·m. Ensures consistent torque application to avoid thread damage or pipe sticking, reducing maintenance costs by up to 40% compared to standard sensors.

Structure & Features

• Built-in stainless steel 316L diaphragm with anti-corrosion coating, resistant to H2S and corrosive drilling fluids.

• IP68 waterproof rating, suitable for subsea and outdoor oilfield installations.

• Integrated CAN bus interface (compatible with MODBUS and DeviceNet protocols) for seamless integration with CPS2000 logging systems.

Applicable Working Conditions

• Onshore oilfields with high temperature fluctuations (-40°C to 125°C)

• Offshore deep-water drilling platforms (depth up to 3,000m)

• Well logging operations with high vibration and mechanical shock (up to 50g)

Maintenance & Operational Tips

• Calibrate the sensor every 6 months using a standard pressure calibrator; avoid direct exposure to drilling fluid during calibration.

• Inspect the cable connector (15m CAN cable with plug, model CPS-KQ-VI) for wear and replace if insulation damage is detected—prevent water intrusion to avoid signal loss.

• Store spare sensors in a dry, temperature-controlled environment; avoid stacking heavy components on top to prevent diaphragm deformation.

2. SK-Series Ultrasonic & Float Level Sensors

Our SK-series level sensors (SK-8C05L, SK-8C06AG) are designed for accurate liquid level measurement in mud tanks, hydrogen generators, and fluid storage systems, addressing the pain point of inaccurate level detection that can lead to fluid overflow or dry running of pumps.

Function & Value

• Ultrasonic Level Sensor (SK-8C05L): Uses non-contact ultrasonic technology to measure liquid level from 0.5m to 10m, with an accuracy of ±2mm. Ideal for measuring corrosive and viscous fluids (e.g., drilling mud, hydrogenated oil) without physical contact.

• Float Level Sensor (SK-8C06AG): Equipped with a copper float (φ3/φ4) for high-density liquid measurement, with a response time of <50ms. Suitable for static and low-flow liquid storage tanks.

Structure & Features

• Ultrasonic sensor: Built-in temperature compensation algorithm to eliminate errors caused by ambient temperature changes.

• Float sensor: Stainless steel float with anti-fouling coating to prevent adhesion of drilling mud residues.

• Explosion-proof design (EX marks) for use in Zone 1 hazardous areas.

Applicable Working Conditions

• Mud circulation systems in onshore oilfields

• Hydrogen generator fluid tanks (model 500 CPS-KQ-VI)

• Chemical injection systems for well stimulation

3. CPS2000 Logging Tool & Control System Components

The CPS2000 comprehensive logging tool (INSITE system) and its supporting components (e.g., multi-serial card, temperature sensors) form a complete data acquisition and control solution for well logging operations.

Core Components & Functions

• CPS2000 Data Acquisition Interface (SJK-2): Central hub for connecting multiple sensors (pressure, torque, level) to the logging system, supporting 8-channel serial communication and real-time data storage.

• Temperature Sensor (SK-8W01A): Measures drilling fluid temperature at the inlet and outlet, with a range of -50°C to 200°C and accuracy of ±0.5°C. Critical for monitoring downhole heat generation and optimizing drilling parameters.

• Solid State Relay Circuit Board (PC08): Controls the on/off of high-power components (e.g., xenon lamp power supply, CPS-2000-024) with zero-crossing switching, reducing electromagnetic interference (EMI) and extending component life.

On-Site Fault Repair Cases (Oilfield Scenarios)

To demonstrate the practical value of our products, we share three real-world repair cases from major oilfield projects, highlighting how our components resolve critical operational issues:

Case 1: Onshore Oilfield in Daqing, China

• Location: Daqing Oilfield, No. 3 Drilling Platform

• Fault Model: SK-8N07G Point Torque Sensor (original sensor failed)

• Fault Description: During drill pipe makeup, the torque sensor displayed erratic signals (fluctuation range: ±500 N·m), leading to incorrect torque application and a risk of thread damage. The original sensor had been in use for 18 months, exposed to high vibration and drilling fluid splashes.

• Load & Data: Drilling torque during makeup: 3,500 N·m; vibration intensity: 30g; original sensor signal stability: ±8% FS.

• Repair & Result: Replaced the faulty sensor with our SK-8N07G electric torque sensor (equipped with anti-vibration damping structure and IP67 protection). Post-repair signal stability: ±0.1% FS; torque measurement accuracy maintained within ±0.2% FS.

• Customer Feedback: "The new sensor eliminated signal drift completely. We reduced thread replacement frequency by 60% and cut NPT time by 12 hours in the first month."

Case 2: Offshore Oilfield in the South China Sea

• Location: South China Sea Deep-Water Drilling Platform (Block A)

• Fault Model: CPS-KQ-VI Riser Pressure Sensor (SK-8Y34A)

• Fault Description: The riser pressure sensor lost communication with the CPS2000 logging system during a storm, with wind speed reaching 40 knots and wave height 8m. The original cable had poor waterproofing, leading to water intrusion.

• Load & Data: Riser pressure during normal operation: 25MPa; communication loss duration: 2 hours; original cable insulation resistance: <1MΩ.

• Repair & Result: Replaced the original cable with our 15m CPS-KQ-VI CAN cable with plug (IP68 waterproof) and reinstalled the SK-8Y34A sensor with a reinforced mounting bracket. Post-repair communication stability: 100% signal retention; pressure measurement accuracy remained ±0.1% FS.

• Location: Ordos Shale Oilfield, Mud Circulation System

• Fault Model: SK-8C06AG Float Level Sensor

• Fault Description: The float level sensor in the mud tank failed to detect liquid level, causing the mud pump to run dry and resulting in pump damage. The original float was made of ordinary stainless steel, which adhered to mud residues.

• Load & Data: Mud density: 1.8g/cm³; liquid level range: 2–6m; original sensor response time: >500ms.

• Repair & Result: Installed our SK-8C06AG float level sensor with a copper anti-fouling float. Post-repair response time: <50ms; level measurement accuracy: ±2mm; pump dry running was completely eliminated.

Frequently Asked Questions (FAQ)

Engineering Best Practices & Avoidance Tips

1. Sensor Installation: When mounting pressure sensors, avoid direct alignment with fluid flow paths to prevent impulse damage. Use a 3-way assembly (SK-TY-02) to buffer pressure surges, especially in high-flow fluid systems.

2. Cable Routing: Route CAN bus cables and sensor cables separately from high-voltage power cables (≥1kV) to minimize EMI. Use cable clips to secure cables and avoid sharp bends that can damage the insulation.

3. Component Replacement: When replacing sensors or control boards, power down the entire CPS2000 system first to avoid electrical surge damage. Keep a record of replacement time and model for traceability, a key requirement for E-E-A-T compliance.

4. Environmental Protection: For sensors installed in outdoor oilfield areas, use explosion-proof enclosures (e.g., Type 2000 explosion-proof box 9N02X) to protect against dust, rain, and UV radiation.
