More Information
Summary:The invention relates to a viscoelastic well cementation packing material. The viscoelastic well cementation packing material comprises the following components in percentage by mass: 20-82.5 percent of high molecular polymer main agent, 3-9 percent of cross-linking agent, 5-9 percent of flow state regulator, 0.5-1 percent of suspending agent, 0-49.5 percent of weighter and 0-22 percent of water. According to the viscoelastic well cementation packing material, the viscoelastic well cementation packing material can be formed underground to enhance the well cementation annular water channeling resistance capacity and improve the well cementation packing quality of oil and gas wells.
