Tectonic movements formed several unconfor- mities in the north-west margin of the Junggar basin. Based on data of outcrop, core, and samples, the unconformity is a structural body whose formation associates with weath- ering, leaching, and onlap. At the same time, the structural body may be divided into three layers, including upper layer, mid layer, and lower layer. The upper layer with good primary porosity serves as the hydrocarbon migration system, and also accumulates the hydrocarbon. The mid layer with compactness and ductility can play a role as cap rock, the strength of which increases with depth. The lower layer with good secondary porosity due to weathering and leaching can form the stratigraphic truncation traps. A typical stratigraphie reservoir lying in the unconformity between the Jurassic and Triassic in the north-west margin of the Junggar basin was meticulously analyzed in order to reveal the key controlling factors. The results showed that the hydrocarbon distribution in the stratigraphic onlap reservoirs was controlled by the onlap line, the hydro- carbon distribution in the stratigraphic truncation reser- voirs was confined by the truncation line, and the mid layer acted as the key sealing rock. So a conclusion was drawn that ＂two lines （onlap line and truncation line） and a body （unconformity structural body）＂ control the formation and distribution of stratigraphic reservoirs.

The Hanjiang Formation of Langhian age （middle Miocene） in the Pearl River Mouth Basin （PRMB）, South China Sea consists of deltaic siliciclastic and neritic shelf carbonate rhythmic alternations, which form one of the potential reservoirs of the basin. To improve stratigraphic resolutions for hydrocarbon prospecting and exploration in the basin, the present study undertakes spectral analysis of high-resolution natural gamma-ray （NGR） well-logging record to determine the dominant frequency components and test whether Milankovitch orbital signals are recorded in rhythmic successions. Analytical results indicate the orbital cycles of precession （~19 ka and ~23 ka）, obliquity （-41 ka）, and eccentricity （~100 ka and --405 ka）, which provide the strong evidence for astronomically driven climate changes in the rhythmic alternation successions. Within biochronological constraint, a high-resolution astronomical timescale was constructed through the astronomical tuning of the NGR record to recent astronomically calculated variation of Earth＇s orbit. The astronomically tuned timescale can be applied to calculate astronomical ages for the geological events and bioevents recognized throughout the period. The first downhole occurrences of foraminifers Globorotalia peripheroronda and Globigerinoides sicanus are dated at 14.546 Ma and 14.919 Ma, respectively, which are slightly different from earlier estimates in the South China Sea. When compared with the global sea-level change chart, the astronomical estimate for the sequences recognized based on microfossil distributions have the same end time but the different initiation time. This is probably due to the local or regional tectonic activities superimposed on eustatic rise which postponed the effect of global sea-level rising. Astronomical timescale also resolves the depositional evolution history for the Langhian Stage （middle Miocene） with a variation that strongly resembles that of Earth＇s orbital eccentricity predicted from

Fifty samples from the source rocks in Member 3 and Member 4 of the Paleogene Shahejie Formation in the Bohai Bay Basin, East China, were analyzed to investigate the distribution, evolution of the molecular maturity ratios C29ββ/（ββ＋αα） and C2920S/（20S＋20R） and their control factors in the natural geological profile and sequence. The results showed that progressive changes in molecular maturity parameters are associated with major changes in thermal evolution of related biomarkers. Increases in the C29ββ/（ββ＋αα） and C2920S/（20S＋20R） ratios result from the difference in the relative rate between generation and thermal degradation of isomers involved. The samples from a hyper-saline environment below 3.5 km in which evaporitic rocks deposited shows high response of Sr/Ba, Sr/Ca, Fe/ Mn, Pr/n-C17, Ph/n-C18 and gammacerane and low response of Pr/Ph. There presents negative reversal of biomarker maturity C29ββ/（ββ＋αα, C29ββ/（ββ＋αα） and Ts/（Ts＋Ym） in the samples from hypersaline environment, reflecting that the gypsum- halite have negative effect on the isomerization of biomarker and thermal evolution of organic matter. The minerals in evaporites also retard the conventional thermal indicators including vitrinite reflectance （Ro） and pyrolysis peak temperature Tmax at the depth below 3.4 km （i.e. 〉3.4 km）, and these parameters also show the inhibition from overpressure in the range of 2.4-3.4 kin. This result will be helpful in the interpretation and application of molecular maturity parameters for similar saline lacustrine basins.

拉曼微探针分析法对单个气液包裹体的化学成分和相态的无破坏性测量来说,目前几乎是唯一最好的方法。但是由于众多因素的影响,特别是主矿物具有较强荧光时,提高信噪比的问题急待解决。本工作对碳酸盐岩储层包裹体样品制成的薄片进行了显微观察、荧光测试及拉曼分析,并进行了空间上横向XY扫描、纵向上深度剖析(Z扫描)和冷热台上变温的流体包裹体差分拉曼光谱测量方法的研究。结果表明,所得到的差谱揭示了包裹体更真实的光谱曲线,消除了主矿物对包裹体的干扰,以较高的信噪比显现出包裹体中流体(-170℃温度下的冰)位于位移波数3 098 cm-1附近的宽拉曼散射峰,明显的改善了信噪比。

柴达木盆地北部块断带断层对油气成藏有控制作用。在剖面上,该区发育3套断层系统,即下部冲断层系统、上部滑脱断层系统和顶部正断层系统。下部冲断层控制烃源岩的分布及深层原生油气藏的形成,上部滑脱断层控制中浅层圈闭和次生油气藏的形成,而顶部正断层对油气藏具有一定的破坏作用。定性分析和定量评价表明,在研究区断层静止期,侧向封闭性由深到浅变好,垂向封闭性由西向东增强;在活动期,断层构成油气垂向运移的关键通道。油气沿断层垂向运移具有上下连通、归一和分隔3种模式,其中上下连通和归一模式的输导能力强,分隔模式的输导能力差。这是造成该区主要构造油气富集程度差异的主要因素。

准噶尔盆地乌尔禾—夏子街地区二叠系至侏罗系发育多期不整合,包括削截及多期削截不整合、超覆不整合、褶曲不整合、断褶不整合和平行不整合。风化剥蚀程度的不均一性使不整合有3种典型岩石组合:底砾岩-风化壳-淋滤带型,主要分布在断裂带北部,呈条带状分布,底砾岩滞留原地,风化壳保存较好,淋滤带发育;水进砂体-风化壳(风化黏土)-淋滤带型,因湖侵导致的远物源搬运,砂层分选、磨圆度都很好;砂泥层-风化泥岩型或砂泥岩叠合型,是多次水进水退形成的。构造部位不同、构造变形强度不同、沉积物源不同是造成不整合结构差异的主要因素。在此基础上,分析了不整合成因模式。乌尔禾—夏子街地区与不整合有关的油藏众多,主要有削截不整合、断褶不整合形成的不整合面遮挡油气藏和超覆不整合形成的地层超覆油气藏。
