The invention relates to a crude oil transportation technics method, in particular to an oil-gas mixture transportation technics method for processing the slug flow at big segment during transporting crude oil, which is characterized in that: an input oil-gas (1) enters into an oil-gas separating cavity (3) of a separating cushioning device (2); part of associated gas separated can serve as the technics self-using fuel (4); the oil-gas can assemble at a liquid collecting cavity (5) of the separating cushioning device (2) and can flow out from an overflow outlet pipe (6) when the liquid level raising to certain height and then can enter into an oil-gas transportation screw pump (7) for adding pressure; then the liquid oil can pass through a pipeline separator (8) to complete the transportation of the external transported oil-gas. Under the condition that flow is plugged at large segment, the invention ensures the normal and effective operation of the oil-gas multiphase flow screw pump,thereby radically prevent
