▎ 摘　　要

NOVELTY - A non-metal degradable self-adaptive temporary blocking ball comprises rigid degradable ball core, and degradable shell layer coated outside degradable ball core. The degradable ball core comprises glycolic acid polymer. The degradable shell layer comprises flexible degradable resin. USE - The ball is used for non-metal degradable self-adaptive temporary blocking. ADVANTAGE - The ball can form good sealing and sealing of perforating gun hole. The initial stage of pressing can realize fast and effective plugging which improves plugging success rate which is good for reducing loss of fracturing fluid.
