在鸭子河构造深层油气勘探现状分析的基础上,提出了川鸭126井须家河组分层以及 油气是否能规模成藏等存在的问题。通过鸭子河构造须二段的沉积相带、砂体展布,以及鸭 子河地区构造演化分析,认为不仅鸭子河地区须二段沉积环境向西存在着相变,而且该 区因不存在印支及燕山期适时古构造,也就不存在油气规模聚集成藏的条件;同时指出鸭子 河地区深层油气的有限规模成藏实为由构造裂缝系统控制的小规模油气藏,属于构造裂缝和 岩性复合圈闭成藏类型。因此认为对鸭子河地区深层的油气勘探应持谨慎态度。
在鴨子河構造深層油氣勘探現狀分析的基礎上,提齣瞭川鴨126井鬚傢河組分層以及 油氣是否能規模成藏等存在的問題。通過鴨子河構造鬚二段的沉積相帶、砂體展佈,以及鴨 子河地區構造縯化分析,認為不僅鴨子河地區鬚二段沉積環境嚮西存在著相變,而且該 區因不存在印支及燕山期適時古構造,也就不存在油氣規模聚集成藏的條件;同時指齣鴨子 河地區深層油氣的有限規模成藏實為由構造裂縫繫統控製的小規模油氣藏,屬于構造裂縫和 巖性複閤圈閉成藏類型。因此認為對鴨子河地區深層的油氣勘探應持謹慎態度。

Based on the exploration analysis of the Yazi Rive r Structure, the authors put forward the questions how to divide the layers of Well CY-126, and if it can for m a large scale reservoir formation in the Xujiahe Group. Through the analysis of se dimentary facies, the distribution of sandstone and the tectonic evolution in th e second m ember of the Xujiahe Group in the Yazi River, the authors think that the sedimen tary facies change does not only exist from east to west in the second member of the Xujiahe Group, but als o it does not exist a large scale reservoir formation because the palaeouplift did not exi st in Indo-China and Yanshan structure movememt period. Meanwhile, the a uthors also point out that the small scale reservoir formation is controlled by tectonic fractures , it belongs to tectonic fracture and lithology complex trap types. So the oil and gas exploration will be carried out cautionsly in the deep layer of the Yazi River area.
