Method for producing solid catalyst component for olefin polymerization, olefin polymerization catalyst, method for producing olefin polymerization catalyst, and method for producing olefin polymer

A method for producing a solid catalyst component for olefin polymerization comprising:

• bringing a magnesium compound, a titanium halide compound, and one or more internal electron donor compounds into contact with each other to effect a reaction;
• washing the resulting product with a first inert organic wash solvent that does not have reactivity with the titanium halide compound, and has a solubility parameter (SP) of 8.0 to 9.0;
• washing the resulting intermediate product one or more times in the absence of the titanium halide compound with a second inert organic wash solvent that comprises a hydrocarbon compound and does not have reactivity with the titanium halide compound, but has a solubility parameter (SP) of more than 9.0;
• and
• washing the resulting product one or more times in the absence of the titanium halide compound with a third inert organic wash solvent that does not have reactivity with the titanium halide compound, and has a solubility parameter (SP) of less than 8.0.
