Triassic is the most promising target for oil/gas exploration in block A, Algeria. The research on its hydrocarbon accumulation conditions and enrichment controlling factors is of great significance for oil/gas exploration within the block. Based on the comprehensive study on evaluation of Silurian source rock, characteristics of Triassic reservoir and such basic petroleum geologic conditions as trap condition, cap rock as well as preservation condition and time and space conditions of hydrocarbon accumulation, it is pointed out that the factors controlling hydrocarbon accumulation in block A, Algeria are hydrocarbon source conditions, the difference in the quality of reservoirs and the effectiveness of gas migration. Oil/gas exploration in block A, Algeria should adhere to the principle of near hydrocarbon source and deal with the two key factors of reservoirs and traps on the basis of fine logging interpretation, reservoir inversion and micro-fracture prediction.
