description The invention relates to an in-situ wet viscous landing oil sludge pretreatment method suitable for a heat treatment technology. The invention mainly solves the problems of adhesion, wall hanging, poor air permeability, low reactivity, aggravated particulate matter emission and the like in a heat treatment process of wet viscous oil sludge. The method is characterized by comprising the following six steps: analyzing and testing original oil sludge, cutting and stripping the oil sludge, performing in-situ conditioning on the oil sludge, screening out large impurities, performing extruding and granulating, and airing the granulated oil sludge. The method has the advantages of saving a large amount of cost for oil sludge transportation and storage, simplifying a process system, remarkably enhancing plasticity, overall binding force, compressive strength, air permeability and reactivity of the oil sludge, improving heat treatment efficiency and effect of the wet viscous oil sludge, reducing equipment operation co
