4 、採用烴源巖生烴史、油氣成熟度、流體包裹體、儲層自生伊利石同位素年代學和圈閉演化史綜合方法，確認焉耆盆地侏羅系油氣藏具有三期成藏的特點，第一期發生在侏羅紀晚期，是盆地的主要成藏期，第二期為侏羅紀末至白堊紀的油氣藏破壞、調整和再分配期，第三期發生在第三紀，是盆地的次要成藏期。The basement of the basin is consist of precambrian crystal basement and paleozoic folding basement, while the cover has undergone the evolution of intra - continental rife in permian, down warped basin in triassic - cretaceous period and inter - mountains basin in tertiary. the main sediments are huge - thick volcanic rock, shallow intrusive rock and tuff in early permian, dark mudstone, marl and muddy dolostone in lucaogou formation in middle permian, huge thick volcanic rock, intruder in tiaohu formation in middle permian, miscellaneous sandy gravel, sandstone and gray mudstone in triassic ( the red is under the gray, and huge - thick dark gray, gray sandy gravel, sandstone, mudstone with coal layer in jurassic
盆地基底由前寒武紀結晶基底和古生代褶皺基底組成，盆地蓋層則經歷了二疊紀的裂谷盆地、三疊紀?白堊紀的坳陷盆地和第三紀后的山間盆地的演化過程。盆地主要沉積了下二疊統巨厚火山巖、淺成侵入巖和凝灰巖；中二疊統蘆草溝組的暗色泥巖、泥灰巖、白雲質巖石以及條湖組的巨厚層火山巖、侵入巖；三疊系雜色砂礫巖、砂巖及灰色泥巖（下紅上灰） ；以及侏羅紀厚層深灰、灰色砂礫巖、砂巖、泥巖夾煤層。This paper studies cretaceous volcanics distribution, rock types, tectonic setting and reservoir characteristics in the western depression of liaohe fault depression through statistics of compound logging data, core observation, thin section identification, cathodeluiminescence, scanning electron microscope, x - ray diffraction analysis, image analysis, rock chemical analysis, isotope age testing, and inclusions temperature testing
摘要通過全區綜合錄井資料的統計、大量的巖心觀察，並利用薄片鑒定、陰極發光、掃描電鏡、 x衍射分析、圖像分析、巖石化學分析、同位素年齡測定、包裹體溫度測定等10餘種方法，對遼河斷陷西部凹陷白堊紀火山巖分佈、巖石類型、巖石系列、形成的構造背景及儲層特徵進行了研究。This clam fossil is from the cretaceous period, approximately 100 million years ago
這個蛤化石來自大約一億年以前的白堊紀時期Under the guide of dynamic system for pool - forming and petroleum system, this research has fully taken advantage of every kinds of data from the area, applied the new idea, new technology, new methods to study tectonic, sedimentary and resource rock. the results suggest that the source rock of permo - carboniferous has undergone three evolution periods. the first gas generation occurs at the end of triassic and the generation stopped during jurassic - cretaceous
該文以成藏動力學系統和含油氣系統理論為指導，充分利用工區以及鄰區的各種資料，運用新思路、新技術、新方法，在構造、沉積、烴源巖評價等基礎地質研究的基礎上，認為石炭?二疊系烴源巖經歷了三疊紀末期以前的一次生氣階段、侏羅紀?白堊紀時期的演化停止階段和早第三紀至今的二次生氣階段等三個階段。分享友人
