  1. 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。
