摘要
Abstract
Temperature and pressure are two significant reasons directly affecting oil production rate. This paper presents a new Fiber Bragg Grating (FBG) based pressure sensor for oil well application. This sensor breaks through domestic laboratory limitations for the oil well application of a pressure sensor and is quite significant for the increase of oil production rate. Its performance parameters are measurement range of greater than 50 MPa, working temperature of -20～170℃,measurement accuracy of 0. 5％FS, and pressure coefficient of up to 41.92 pm/MPa after encapsulation. This sensor has such positives as online, real-time and long-term detection for the temperature and pressure in an oil well, simple structure, high measurement accuracy, intrinsic safety and easy networking. It has been applied to the Tianjin experimental well of China National Offshore Oil Corporation (CNOOC).关键词
