High-Reliability Crude Oil Mud and High-Viscosity Solid-Containing Medium Pressure Measurement

Core technology

　　In oil and gas exploration and development, the mud circulation system is often referred to as the “blood” of drilling operations. The precise, reliable, and continuous monitoring of its pressure parameters directly affects well control safety, drilling efficiency, and resource protection. However, traditional pressure measurement methods frequently encounter industry-wide challenges when dealing with mud media that are high in solids content, highly viscous, strongly corrosive, or prone to crystallization. These challenges include clogging of pressure-measuring ports, erosion of diaphragms, signal drift, and even complete sensor failure. Such pain points not only lead to data interruptions and a sharp increase in maintenance frequency but also—more critically—in key stages such as drilling, fracturing, and cementing—can trigger safety risks due to distorted pressure sensing, severely hindering the advancement of process optimization and intelligent decision-making.

　　To systematically address the challenges mentioned above, Sensor Nobleman has launched a highly reliable pressure measurement solution tailored for the entire lifecycle of oilfield drilling mud. At the heart of this solution is a robust flat-diaphragm anti-clogging design coupled with an all-welded, dynamic-seal-free architecture. The solution covers critical measurement points—from the drilling fluid inlet and mud pumps, through high-pressure manifold systems, to vibrating screens and fracturing-acidizing processes—and supports customized corrosion-resistant configurations. Leveraging sputtered thin-film sensing technology and intrinsically safe explosion-proof certification, this solution ensures millimeter-level accuracy and long-term maintenance-free operation even under extreme conditions: temperatures exceeding 300°C, pressures reaching hundreds of megapascals, and continuous vibration. We are committed to building a continuously online “industrial sensing nerve” for mud systems, making pressure data a solid foundation for well-control safety and process intelligence.

Core technology

　　The core nanofilm technology independently developed by Sensor Nobleman serves as the fundamental guarantee for achieving high reliability and long service life in oilfield mud pressure measurement. This technology integrates, in a deep and synergistic manner, specialized metallic elastomers, novel sensing materials, and vacuum atomic thin-film deposition processes, enabling end-to-end, fully independent design and manufacturing—from the sensing chip all the way to the finished sensor. The dedicated sensors built on this technology not only ensure high precision and low-temperature drift but also significantly enhance their long-term stability and operational adaptability in mud environments, thanks to their solid-state, flat-diaphragm anti-clogging structure and outstanding vibration- and shock-resistant properties. These sensors can precisely handle complex conditions such as high viscosity, easy crystallization, and fluctuating solid content, providing continuous and reliable data support for critical applications including drilling pump stroke monitoring, wellhead pressure monitoring, and fracturing-acidizing operations. As a result, they empower the development of intelligent and safe oilfield systems.
