Abstract: Through studies on a series of features in the Jigesen structural zonesuch as structural, sedimentary, reservoir property,predictive evaluation, genetic features of the reservoir beds, and control distributive trends of oil, water and gas accumulations,as well as factors, it is realized the zone is the main oil entrapment region in the Erennaor depression for its advantageous lo-
cation with respect to the oil source trough in the depression and well developed sand bodies coupled well with structural heights of the traps. Successive exploration and development indicated this zone being of great oil reserves, and the structure group was discovered as a large scale oil field with up to 10 million tons of geological oil reserve.

Key words: distribution of hydrocarbon, accumulation, lithology, exploration, Erlian basin
