In the exploration and development process of oil and gas wells, production personnel need to continuously conduct dynamic testing of various oil and gas reservoirs, monitor and measure the formation pressure parameters of oil and gas reservoirs in real time, accurately evaluate oilfield productivity based on these parameters, optimize the evaluation methods of oilfield productivity, determine reasonable development plans, and ensure safe production. The process of China’s petroleum industry has developed rapidly. In order to increase oil production, various large and small oil fields have started research on the re exploitation of old oil fields. Some of these process measures, such as fracturing, acidification, and downhole water injection, need to accurately measure the pressure data of oil and gas reservoirs during the process of petroleum development to determine the specific situation of improving production wells. في نفس الوقت, in daily related oil production work, the data of downhole formation pressure also provides data support for determining development indicators for the oilfield.

الألياف الضوئية sensors have attracted widespread attention due to their advantages such as insensitivity to electromagnetic interference, ability to withstand extreme harsh conditions, absence of electronic components at the sensing end, high-precision measurement of wellbore and wellsite environmental parameters, small device size, relatively easy installation, and ease of networking.

في الوقت الحالي, commonly used fiber optic sensors mainly include micro bent fiber optic sensors, interferometric fiber optic sensors, Bragg grating fiber optic sensors, أجهزة استشعار الألياف الضوئية الموزعة, إلخ. The micro bent fiber optic sensor is susceptible to measurement accuracy issues such as light source fluctuations, خسائر ثني الألياف, connection losses, and detector noise; Interference type sensors require high consistency in the optical path, which limits the flexibility of the system; أجهزة استشعار لشبك الألياف Bragg have problems such as relatively low measurement accuracy and resolution, complex system structure, and difficulty in demodulation.
Underground fiber optic pressure gauge is used to solve the problems of complex structure, difficult construction, low accuracy, ضعف الاستقرار, live operation, large fluctuation of light source, and inability to use conventional pressure gauges in high temperature, high pressure and high corrosion environments of existing pressure monitoring instruments.
