Oil extraction method for salt-containing oil well

The invention discloses an oil extraction method for a salt-containing oil well, and belongs to the technical field of oil extraction. The method comprises the following steps of continuously doping clean water or a salt inhibitor solution into a shaft of the target salt-containing oil well, wherein the clean water or the salt inhibitor solution enters the shaft as salt removal and prevention liquid to carry out salt removal and prevention operation; and performing oil extraction operation in cooperation with oil extraction equipment while the salt removal and prevention operation is carried out, wherein the oil extraction equipment adopts a gap bridge pump to deepen a tail pipe. The amount of the doped clean water or salt inhibitor solution is obtained through the following formula, wherein V is the liquid doping amount with the unit of m /day, Qw is the water yield with the unit of m /day, Gamma w is the specific gravity of produced water and the dimensionless amount, Cs is the salt concentration of initial
