Fluid Production from Damaged Wells in Changqing Oilfield

With the continuous advancement of oilfield development, the number of oil and water Wells damaged by casing corrosion has been increasing year by year, seriously affecting the balance between injection and production and significantly reducing the potential for recovering the remaining oil. Because the water content trend of casing damage Wells is similar to that of injection Wells, identifying casing damage Wells has always been a challenge. This study compared the differences in the production fluid communities between normal Wells and casing loss Wells.
