The synthesis and evaluation of clay stabilizer for invisible acid completion fluid is a complex and important process,which is directly related to the completion effect and reservoir protection of oil and gas wells.The following is a comprehensive overview of the synthesis and evaluation of clay stabilizers for completion fluids.The PDADMAC24 synthesis process is simple,the types of chemical raw materials used are few,and the production pro-cess is simple and easy.The laboratory test results show that PDADMAC24 is a very effec-tive clay stabilizer for completion fluid.It has good compatibility with corrosion inhibitors and additives,high temperature resistance,strong stabilizing effect,and high anti-swelling rate of more than 91.00%.It can obviously improve the effect of completion and reservoir protection,and the construction is simple.
