Polymer temporary plugging agent is mainly used for oil and gas well reservoir reconstruction (such as fracturing, acidification, water shutoff, etc.) to temporarily block the target layer that does not need to be modified. After it stays in the reservoir for a certain period of time, it can gradually dissolve in the reservoir fluid and then be discharged. The temporary plugging agent is non-toxic and harmless, and has good compatibility with other additives. It has the characteristics of water swelling, high initial strength and good plugging effect. At the same time, it has good medium and low temperature delayed dissolution and salt resistance. It is easy to mix liquid during construction, convenient to construct, and has little pollution to the temporary plugging layer.
Storage and transportation conditions
1. The polymer temporary plugging agent should be stored in a cool and ventilated place, and should be kept away from heat and fire sources.
2.The polymer temporary plugging agent should be protected from impact during transportation. It is strictly forbidden to mix with food for transportation.
