Abstract: The compatibility between crude oil stored in underground water-sealed cavern and epoxy resin grouting material used for anti-seepage is defined as follows: the quality of crude oil and the mechanical properties of epoxy resin grouting material may change after long-term contact between the two organic materials. Static immersion test in crude oil was designed under simulated conditions to compare the changes of characteristic element content of crude oil and the quality, strength, molecular structure and surface morphology of epoxy resin cured materials before and after the immersion test. Results show that the composition of crude oil did not change significantly, nor did it adversely affect the mechanical properties and structural morphology of epoxy resin cured materials at 40 ℃. No chemical reaction occurred. It is concluded that the crude oil has good compatibility with epoxy resin grouting material under normal operating conditions.

Key words: underground water-sealed caverns, anti-seepage, crude oil, epoxy resin grouting material, compatibility
