Abstract:A carbonate reservoir in the Tarim oilfield has a deep burial depth (5000 to 7000 m), high temperature (130 to 150°C), and long horizontal section (600 to 1600 m). It is a heterogeneous formation with obvious interlayer physical differences. The requirements for using a multistage acid fracturing process (5 to 12 stages) in the stimulation program for this complex horizontal well completion highlight the challenges associated with ensuring tubing string integrity.
