coal forming period
解釋
聚煤期-
Through research, the organic matter of source rocks in carboniferous - permian coal measure strata began first hydrocarbon - generating in mesozoic, and the first hydrocarbon - filling took place. but, because of yanshan movement later, the carboniferous - permian strata rose, as a result, the first hydrocarbon - generating and reservoir - forming paused ; in early tertiary period, because carboniferous - permian strata dipping forward east originally turned into dipping forward west, the prototype of faulted block began to form gradually ; by the end of sha - 3 period of early tertiary, the paleogeotherm of carboniferous - permian strata exceed the mesozoic ' s temperature again, and accordingly, abundant hydrocarbon was generated and expulsed secondly. the trap continued to develop ; from the end of late tertiary to quaternary, the second hydrocarbon - generating and expulsing got to its peak, and the second reservoir - forming was over
研究表明，本區石炭?二疊紀烴源巖在中生代發生一次生烴和排烴，並有油氣充注，后因燕山運動導致地層抬升，一次生烴和成藏過程中止；在早第三紀，原來東傾的地層變為西傾，斷塊圈閉開始具雛形；至早第三紀沙二末期，石炭?二疊系的大部分地層古地溫再次超過中生代一次生烴的溫度，開始二次生烴和排烴，圈閉持續發育；晚第三紀末?第四紀，二次生烴、排烴達到高峰，二次成藏完成。 -
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。 -
