通过对衰减方程进行求导,然后再积分的方法,推导得到了衰减方程参数之间的关系:6=dc。由此提出了一种求解方程参数的新方法。该方法克服了传统采用近似法确定衰减方程参数的不足,具有简单、方便、快速、精确的特点。经实际算例验证表明,方法是有效、可靠的,易于被油气藏工作者掌握和使用。 相似文献

南京地区金子运动与黄马青群底部石灰岩质角砾岩的成因 总被引:3,自引:0,他引:3
1935年朱森[1]等研究宁镇山脉地质时,首先提出中三叠世末期这里发生过重要的地壳运动,称金子运动,上三叠统黄马青群底部有石灰岩质角砾岩不整合在下中三叠统青龙群之上。1945年喻德渊[2]研究了安庆地区的同一地壳运动,黄马青群底部角砾岩同样不整合在青龙群之上,称淮阳运动,并强调淮阳运动结束了古生代以来下扬子地区长期海侵的历史,在地质发展中具有重要的变革作用。李四光[3]从区域的角度肯定了金子运动(淮阳运动)在华南和东南亚地区的地质意义。1962年以来,不少单位和个人[4,5,6]对此期运动作了研究,并肯定了它的存在。 相似文献

THE CONFIGURATION OF THE BASEMENT BENEATH THE ZAGROS BASIN 总被引:4,自引:0,他引:4
It has long been recognised that the deposition and deformation of the Phanerozoic cover in the Zagros Basin (mountains plus foreland) was strongly influenced by the reactivation of old tectonic fabrics in its basement. Facies boundaries and structures trending north-south and NW-SE can be attributed to the reactivation of Pan-African sutures and Najd faults which are exposed in the Nubian-Arabian Shield. However, to the east of a projection of the Oman line SWwards into the Rhub Al Khali Basin, cover structures have a NE-SW trend which is not seen in Arabia. This boundary may overlie a Pan-African suture between Arabia and India (Somalia or Pakistan).
Data including magnetic intensities, geothermal gradients and isopach maps are used here to distinguish old faults which were reactivated in the basement from more recent faults formed in the cover by Zagros shortening. Old faults trending NW-SE are interpreted as having reactivated episodically since the Permo-Triassic opening of Neo-Tethys; perhaps more significantly, the basement faults that reactivated in the East Arabian Block since then trend north-south. The basement configuration is clarified by extending a modified East Arabian Block across the Zagros to an "East Arabian-Zagros block" in which the NW trend of the Zagros lies between two syntaxes. This suggests a new tectonic framework for the region. The repeated reactivation of basement faults throughout the East Arabian-Zagros Block controlled source rocks, traps and seals for the supergiant and giant oil and gas reserves which are present at various stratigraphic levels in different areas. 相似文献

大别山东南缘前陆盆地经历了由海相—海陆过渡相—陆相的演化历程,具有复合叠合盆地特征。从盆地层序上看,早中生代陆相前陆沉积体系下伏晚古生代海相被动陆缘沉积体系;从烃源岩系和含油气系统特征上看,具有陆相和海相两大套烃源岩系和成油气体系。其中,前陆盆地下伏海相被动陆缘烃源岩的优劣和保存条件是能否形成油气藏的关键。研究证明,晚古生代海相被动陆缘沉积发育优质烃源层系,热演化中等偏高,油气兼生;海相和陆相碎屑岩具有良好储集条件;海相和陆相蒸发相含膏岩系为优质盖层,生储盖配置关系良好,具有形成油气赋存的基本石油地质条件。 相似文献
