Abstract

During CO2 flooding and storage, influenced by mechanical factors, wellbore integrity may be compromised, leading to gas channeling and leakage. In response to this problem, a low-temperature (30-45 ℃) curable methyl methacrylate (MMA) resin wellbore repair system was developed using methyl methacrylate as the main agent, with the addition of redox initiators and cross-linking agents. Performance evaluation of the system was subsequently conducted. The study shows that at 40 ℃, the initial setting time of this resin repair system is 8.2 hours, and the curing time is 10.4 hours; the repair system has good injection performance and adhesion performance, with a surface tension of 27.1 mN/m, and contact angles with sandstone, N80 steel sheet, and oil well cement are all less than 30°. The bonding strength at the cement-steel pipe interface is increased by 13.15 times compared to before repair. The repair system has good CO2 channeling sealing performance and CO2 aging resistance. After repairing the cement-steel pipe interface, the CO2 breakthrough pressure is 26.78 MPa; under CO2 aging conditions, the compressive strength and CO2 permeability of the quartz sand consolidated body change by less than 5.0% within 30 days; this resin repair system can enter micro-pores with sizes of 20-100 μm and tightly fill them after curing. This wellbore repair system has important application value for CO2 flooding and storage in low-temperature reservoirs.

Key words： CO2 flooding and storage; wellbore integrity; wellbore repair; methyl methacrylate; resin
