Applications of Distributed Optical-Fiber Monitoring Technology in Leak Monitoring of Injection Wells

Wellbore integrity is an important guarantee of safe and efficient production in oilfield. The pipeline leakage in injection wells will not only impact the normal production of oil wells, but also reduce oilfield development efficiency and oilfield recovery rate. Through pipeline leakage monitoring,...

description Wellbore integrity is an important guarantee of safe and efficient production in oilfield. The pipeline leakage in injection wells will not only impact the normal production of oil wells, but also reduce oilfield development efficiency and oilfield recovery rate. Through pipeline leakage monitoring, the location and type of pipeline leakage can be found. Accordingly, appropriate governance can be adopted timely to reduce losses. The distributed optical-fiber monitoring technology can real-time continuously monitor downhole temperatures and acoustic profiles. The distributed optical-fiber monitoring technology is applied to monitor pipeline leakages in injection wells to increase the well-logging efficiency and monitoring success rate. The measuring principle of pipeline leakage monitoring based on distributed optical-fiber monitoring technology is introduced in this paper. Taking the leakage of injection wells as examples, the data response characteristics of the instrument under different conditions of tubing leakage, casing leakage and bottom hole channeling are analyzed. Field applications have shown that the application of distributed optical-fiber monitoring technology can monitor the leakage position of injection wells in real time, to locate the situations of casing leakage, tubing leakage, and bottom hole channeling. The technology can provide technical support for formulating solution of pipeline leakage monitoring.
