Tubing Defects

W3S开发了一项用于测量油气井液位的专利技术。该传感器系统利用微波雷达信号的反射来测量单个和多个流体界面，在静态和动态条件下都具有很高的精度。这项技术的突出特点是完全非侵入性；该系统可以永久安装在井口，并提供连续的、接近实时的反馈，无需进行油井干预。目前的项目旨在扩展系统的功能，以检测（并在可能的情况下量化）油管壁上不同类型缺陷的存在。在程序中要考虑的缺陷类型包括侵蚀、腐蚀和结垢。该项目的成功将提供一种能够提供液位信息和生产管道状态监测的传感器。由于传感器可以永久安装在井口上，因此可以记录缺陷形成的速率。

W3S has developed a patented technology for measuring fluid levels in oil and gas wells. The sensor system uses the reflection of microwave radar signals to measure both single and multiple fluid interfaces to a high degree of accuracy in both static and dynamic conditions. The outstanding feature of this technology is that it is wholly non-intrusive; the system can be permanently fitted to the wellhead and provide continuous, near real time feedback negating the need for a well intervention. The current project aims to extend the capabilities of the system to detect (and, where possible, quantify) the presence of different types of defects in the tubing wall. Types of defects to be considered within the programme include erosion, corrosion and scaling. The success of the project will deliver a sensor capable of providing both fluid level information and condition monitoring of the production conduits. Since the sensor may be installed permanently on the wellhead, the rate of defect formation may be recorded.
