Reservoir quality varies greatly in the Shahejie Formation in the Dongying Sag. It is essential to analyze the variation and mechanisms of reservoir quality for determining the controlling factors based on cores, porosity measurements and fluid inclusion techniques and so on. The sandstones in the fluvial, （fan） delta-front have the best reservoir quality due to the depositional conditions mechanically controlling the petrology configuration and the primary porosity, and chemically influencing the diagenesis and development of secondary pores. The activity of the boundary faults and the sedimentary facies dominate the variation of reservoir quality in different areas and intervals. The reservoir quality varies with the position of sandstone beds in different vertical models of sandstone and mudstone. This mainly arose from the strong cementation or strong dissolution in the sandstone caused by the diagenesis evolution of adjacent mudstone. With higher oil saturation reservoir quality is better because the hydrocarbon charge favors dissolution and restricts cementation. Diagenesis, depositional conditions and tectonic setting are the key controls of reservoir quality in the Shahejie Formation of the Dongying Sag.

由于认识到深水储层中富存烃类,碎屑岩深水扇引起了地质学家的兴趣。近年来,碎屑岩深水扇的研究取得了相当大的新进展,回顾和总结近年来该领域取得的进步和提出的新观点,总的来说,这些新的观点包括:碎屑岩深水扇不仅在低位体系域时产生,在沉积供给充足的高位体系域时也能够出现,但有时即使低位体系域时也不能形成深水扇;碎屑岩深水扇通常为浊流成因,但也有一些为碎屑流引起,其内部向上变粗或变厚的反韵律不明显。基于这些新观点,一些新的深水扇模式被提出,这些新的碎屑岩深水扇的模式对其形成和性质的因素,如海平面变化、构造、沉积速率、深水扇类型和性质等,考虑更加全面。结合这些新的认识,提出的深水扇模式包括:富砾、富砂、泥砂混合和富泥型模式,而每种又根据物源的性质分为点物源,线物源和多物源、这些模式考虑因素更加全面、精确,更能反映深水扇的实质,它是深水烃类勘探预测砂体分布有效的工具。

潮汐沉积不仅是重建古地理沉积环境和古气候的重要依据,而且同时也是油气勘探的重要储集层类型。在月球和太阳的引力作用下,地球上海平面发生周期性涨落形成潮流。潮流的方向和流速具有周期性变化的特征,这决定潮流在沉积物的搬运和沉积过程中与其他类型的流体有所不同。潮汐作用过程可形成多种沉积构造或沉积特征,例如潮汐韵律层、过渡性层理、潮汐束、再作用面、复合交错层理、双向交错层理、双黏土层、浮泥沉积等。这些沉积构造或沉积特征发育在不同的潮汐沉积环境中,受到复杂的潮汐沉积过程的控制,使得沉积体系的内部构型和空间分布相对复杂。在油气勘探实践中,需要对沉积微相进行精细刻画,通过岩石记录反推沉积过程,进而预测相应的沉积微相和砂体展布规律。作者通对潮汐形成机制和影响因素、潮汐搬运和沉积过程、潮汐作用相关的沉积构造或特征以及相应的沉积环境进行梳理和总结,旨在加深国内学者对潮汐沉积的认识,了解潮汐沉积的研究进展,并为相关油气勘探和开发提供一定的科学指导。

澳大利亚西北大陆架卡那封盆地北部晚-中中新世到上新世发育硅质碎屑岩的三角洲沉积。部分三角洲朵叶体在陆架坡折附近沉积（陆架边缘三角洲），而其他朵叶体在向陆后退或夭折前并没有延伸到同时代的陆架坡折处。陆架边缘三角洲主要集中在研究区北部，陆架边缘坡折的平面形态是从线性变化为向海一侧凸出的形态。陆架边缘三角洲的位置和特征也对边缘进积走向的变化和陆架边缘轨迹产生显著影响。中中新世晚期-晚中新世，南部陆架边缘坡折，总进积距离为13km，不发育陆架边缘三角洲；在陆架边缘三角洲发育区域的北部坡折进积约34km；中部地区的三角洲进积距离没有北部大，以加积特征为主，分布在陆架坡折向陆数千米的范围。这表明陆架边缘轨迹分析的适用条件只有在陆架边缘三角洲发育的地方沉积物供给充足，陆架边缘轨迹特征与相对海平面波动的响应才可靠。在同时代陆坡上发育典型的小规模侵蚀（约400m宽），甚至在三角洲达到陆架坡折前也能看到此侵蚀现象。然而，就在活动陆架边缘三角洲下倾方向的陆坡沟槽显示对下伏地层更大的侵蚀，陆坡沟槽（宽大于1km，深度约100m）比侧向上偏移三角洲沉积中心的同时代侵蚀水道（宽0．7km，深约25m）更宽、更深。本研究表明陆坡沟槽尺寸的变化是由于紧邻陆架边缘三角洲地区沉积重力流产生更大侵蚀的结果。同时，沟槽也进一步侵蚀（达6km）到活动陆架边缘三角洲地区的外陆架。

A high strength structure steel plate --brand jG785E, which with more than 690MPa yield strength ,more than 47 joules toughness at minus 40℃ has been developed by jigang of Shandong steel Group P. R. China. The steel plates can be easily welded in engineering structure due to its lower carbon equivalent value. The maximum thickness of heavy plate is 50.88mm (2 inch), the yield strength is 710-860MPa, the toughness of steel plate is 139~336j at the temperature of - 40℃ . The microstructure of steel plate is lower carbon Bainite. The main solid dissolve elements are silicon and manganese. All parameters of reheating, rolling and accelerating cooling are controlled strictly. This TMCP procedure can ensure to get better mechanical properties of steel plates, and to keep the market competitive power and lower cost of manufacture. The cleanness of steel is high by refined in ladle furnace (LF), the contents of P and S is lower. It is the low carbon Bainite microstructure that possesses the high strength, excellent lower temperature toughness and better weld-ability without preheat process. The jG785E is typical brand of the jigang’s high strength steel brands as the S690QL conforms to EN10025-6 and as the ASTM A514M conforms to USA quenching and tempering steel specification.
