Application Research of A New Technology of Shifting Sleeves
This paper introduces a new sliding sleeve switch tool.By connecting downhole tool string with coiled tubing and optical fiber device,it can accurately locate the position of sliding sleeve and monitor downhole load,pressure,temperature and other parameters in real time.By processing and interpreting the measured data on the ground,it can accurately judge the downhole situation and realize reliable switching operation of sliding sleeve.And through the change of CCL curve to determine whether the sliding sleeve operation is in place,saving a lot of later operation cost and time caused by operation errors.
