    Abstract
  • In wellbore reconstruction operations such as repairing damaged casings and remedial cementing, oil and/or gas zones need to be temporarily plugged off. To perform this job, a degradable compound core-shell structure gel temporary plugging agent was designed and developed with raw materials AM and PLA. The core-shell structure uses PLA as the core and PAM as the shell. The temporary plugging agent is synthesized through inverse suspension polymerization, with MBA being the crosslinking agent. The temporary plugging agent was molecularly analyzed with FT-IR and TGA, and its performance was compared with polyacrylamide-type temporary plugging agents used in field operations. The results of the experiments show that the degradable temporary plugging agent has good thermal stability, and at temperatures up to 206℃, there is no thermal degradation of the temporary plugging agent taking place. The degradable temporary plugging agent can be used in wellbore reconstruction in these formation conditions: 60℃-90℃, pH≤11 and salinity≤50 g/L. The field operation has proved that the degradable temporary plugging agent is equivalent in performance to polyacrylamide-type temporary plugging agents in plugging formations and removing formation blockage, but has better high temperature stability, causes lower formation damage and is more cost effective, and water injection into wells operated with this degradable temporary plugging agent can be earlier restored.
