The invention relates to a neutral blocking remover composition for oilfield oil extraction, which is prepared from the following components in parts by weight: 30-35 parts of acrylic acid-methyl acrylate copolymer, 44-50 parts of diethylene triamine pentaacetic acid, 30-35 parts of sodium polyepoxysuccinate, 30-35 parts of amine malate, 10-14 parts of sodium alkyl sulfonate, 5-8 parts of amine hydroxy ethylidene diphosphate, 10-14 parts of hydrolyzed polyacrylamide, 12-17 parts of atlapulgite, 20-25 parts of sodium persulfate, 7-10 parts of sodium lignosulfonate, 5-8 parts of tannin, 12-16 parts of sodium malate, 5-8 parts of sodium sulfosuccinate, 5-8 parts of starch, 9-12 parts of methyl lactate, 0.2-0.3 part of vanadium pentoxide and 0.1-0.3 part of diisobutyl carbinol. The neutral blocking remover composition for oilfield oil extraction has the advantages of high blocking removal speed, no corrosivity due to neutrality and no dead area, can quickly dissolve the material scales, clean the oilfield stratum and remove blocking, and does not generate the phenomenon of precipitation or secondary blocking; and the cleaning waste liquid does not need to be subjected to sewage treatment after returning to the ground.
