REVIEW OF OIL CRACKED GAS FORMATION,IDENTIFICATION AND MIGRATION
原油裂解气的形成、鉴别与运移研究综述

On the basis of the researches of oil cracked gases at home and abroad, this paper reviews the cracked gases formation models, the generation mechanism and kinetic process, the catalytic effects of metals for oil cracked gases, the migration fractions of natural gases, and the identification indexes of cracked gases. The formation of the oil cracked gas pools in some basins of China are also discussed by combining the previous studies and the recent progress on the study and exploration of oil cracked gases.
