多点式光纤压力、温度监测系统在水平井的成功应用

Successful application of multipoint optical fiber pressure and temperature monitoring system in horizontal wells

为了增加井下温度压力测试仪的耐高温、抗干扰性以及使用寿命,研制了多点式光纤式压力、温度监测系统,可以在一根1/4″的钢管内最多连接16支压力计,实现多点测试功能。该系统已在渤海油田成功应用,可以满足生产井动态监测的实际应用要求。

In this paper,multipoint optical fiber pressure and temperature monitoring system is developed to improve the hightemperature resistant,interference immunity and service life of downhole pressure and temperature testers.The function of multipoint testing can be realized by connecting pressure gauge inside the steel pipe and the number of pressure gauge can reach to 16 at most.This system which has been successfully applied in Bohai oilfield can fulfill the practical requirement of dynamic monitoring of production well.
