迷宮密封是一種通過曲折通道增大流動阻力來實現封嚴的非接觸密封,通常用於密封氣體,廣泛應用於航空、能源、流體等領域的動力機械中。The regularity of accumulation distribution is ascertained and directs the exploration orientation. the main results obtained in this paper are : 1. the analyses of hydrocarbon - bearing rock, reservoir, caprock and oil & gas reservoir indicate the source of oil & gas, the space for reservoir, requirement for preservation, reservoir type and its basic characters. 2. it is realized by the analyses of sealing up capability of caprock and faults, and fault ' slatter stability from microcosmic and macroscopic that the wide - spread regional caprock of nm t prevented oil & gas of neogene from diffusing fault movement in neogene less violated and fault displacement decreased, which are advantageous for the preservation of oil & gas reservoir. and latter structure movement usually formed the accunulation of oil & gas in neogene. 3. the research of history of hydrocarbon generation and expulsion of main hydrocarbon - bearing rock in qikou depression reveals the threshold depth and the fime of hydrocarbon generation and expulsion
項目研究取得了如下認識: 1 、對烴源巖、儲集層、蓋層及油氣藏展開分析,明確了歧口凹陷上第三系油氣藏的油氣來源、儲集場所、保存條件和油氣藏類型及其基本特徵; 2 、從微觀和宏觀上對蓋層的封蓋能力以及斷層封堵和後期穩定性進行分析,認識到明下段區域蓋層的廣泛分佈阻止了上第三系油氣藏的油氣逸散,同時上第三系斷層活動減弱,斷距較小,對油氣藏的保存較為有利。
