Abstract: There are two constraints for a temporary plugging agent.One is the diverting effect，the other is oil-soluble，the oil soluble，acid soluble and suspension stability of the YRC-1.A new oil soluble temporary plugging agent is studied，and the influence of different factors on the temporary slugging rate and plug removal rate of the YRC-1 is investigated with the core flow experiment.At last，the YRC-1 is applied in oil field.The results show that，the YRC-1 has good oil-soluble and acid insoluble properties，better suspension stability and good diverting effect.In addition，the YRC-1 has many advantages such as high temporary slugging rate，releasing temporary，slugging automatically after operation and operating easily in-situ.

Key words: oil soluble, acid soluble, suspension stability, temporary plugging agent, temporary slugging rate, blocking removal rate
