Application and Prospect of Distributed Temperature Sensor in Oil-Gas Exploration Development

Obtaining temperature information is of great significance to distinguish borehole conditions, monitor oil-field performance, and optimize working system after hydrocarbon exploration and production started. Distributed temperature sensor is developed successively at home and abroad on the issue of gaining continuous temperature profile, which enables the obtainment of wellbore temperature profile over a certain period of time thus ensuring good reliability and accuracy. Fundamental ideas and characteristics of distributed temperature sensor measurement system are introduced in this paper, especially its application status in the process of hydrocarbon exploration and production both at home and abroad. Solutions are presented based on the current deficiency analysis and application prospects are also predicted.
