On the east terrace - fault slope of the depression, the sedimentary mode of fan - shaped delta - slump turbid fan - deep lake facies are developed. on the long axial direction of fula depression, the southeastern groove was filled with a large scale delta which was the main sources, the other little delta limited by the 3 syndepositional fault was distributed down the slope edge of the northern sub - depression. this stage developed a favorable oil sources, reservoir and regional seal which formed the good matching relations of generation, reservoir and seal in the time - space zone

With the tectonic uplift of the source area and the climate turning dry, the coal forming period was over, the fluvial system and fluvial - delta system became to play a major role. based on the study of former researchers and the theory of deep basin gas reservoir forming, the deep basin gas trap in the ordos basin is analyzed and is supposed to form in the ramp of the basin. it is supposed that the hydrocarbon of the deep basin gas trap is mainly composed of coal, carbonate and carbonaceous shale and with the " upper water seal " in the north of the study area the g
根據深盆氣成藏理論和前人的研究成果，分析了深盆氣藏的分佈類型，認為鄂爾多斯盆地深盆氣藏屬于盆地斜坡成藏類型；認為深盆氣的源巖以煤、炭質泥巖、暗色泥巖和碳酸鹽巖為主；北部氣水倒置、東部露頭區有天然氣逸出；氣藏具有多重壓力系統；成藏機理主要是氣體動態的運移與聚集，穩定的構造背景有利於氣藏的大面積保存。
