Abstract:

Based on the temporary plugging balls and temporary plugging agents used in fracturing of oil and gas fields in China, this paper systematically summarized the temporary plugging mechanism, performance characteristics, and application status of temporary plugging products synthesized through different processes and formulas. The dissolution characteristics of each product were introduced, and the existing problems in the water?soluble temporary plugging balls and temporary plugging agents were pointed out through a combination with the requirements for the development of green environmental protection of oil and gas fields. Finally, the future development direction of temporary plugging products was prospected.

Key words: water soluble polymer, staged fracturing, temporary plugging and steering fracturing, degradation
