Archie's electrical parameters of complex pore texture in sandstone reservoir.;2. Based on methods of core analyses,petrographic images,capillary pressure curves and T2 relaxation time curves of nuclear magnetic resonance,the microscopic characteristics of pore texture and evaluation for the Fu-Yang oil reservoirs are comprehensively studied.

根据岩心、岩石图像、毛细管压力曲线分析和核磁共振测量T2弛豫时间曲线等方法，对三肇地区白垩系泉头组扶、杨油层低渗透储集层的孔隙结构进行评价及综合研究，讨论3个问题：(1)储层中孔隙度和渗透率的关系；(2)孔隙结构的微观特征及其对渗透率的影响；(3)储层的渗滤能力、可动流体饱和度及储层评价。

Two carriers are likely to be used in paleotemperature reconstruction: carbonate and iron oxides.

在白垩系陆相红层古温度恢复过程中可能普遍使用两种载体：碳酸盐岩及三价铁氧化物。

No mere sea, though, could accomplish anything with this solid iron-riveted wall — which, at 50 feet from high-water mark, is four feet thick, if one inch ........

尽管单凭巨浪不可能有损于这用铁板加固的塔墙一这墙至高潮标以上五十英尺有四英尺厚，如果一英寸……灯塔所坐落于其上的基石在我看来似乎是白垩

The results show that the organic matter in the dark limestones of the lower Cretaceous is of medium abundance, good type and proper maturity. The limestones have hydrocarbon-generating potential.

研究结果表明，该盆地下白垩统暗色碳酸盐岩的有机质丰度中等、类型较好、成熟度适中，具备了形成油气的条件。

The results show that: 1 the globally distributed CORBs were mainly present in late Cretaceous; 2the paleoenvironment of the CORBs is deep water of low latitude area in general; 3the lithologies are mainly consisted of red shale, red limestone, red marlstone, red mudstone and red siliciclastic shale; 4 the content of organic carbon is quite low.

通过对比，认为：1这些全球分布的大洋红层主要出现在晚白垩世，2一般分布在深水环境、低纬地区，3在岩性上，主要由红色页岩、红色灰岩、红色泥灰岩、红色泥岩、红色硅质页岩几种岩性组成，4有机碳含量普遍较低。

Marlstone samples from the Early Cretaceous Shangkuh Formation in the Jianzishan section and geological pits in Dawu＇ergen were analyzed systematically using the polarizing microscope, fluorescence microscope and freezing-heating stage.

利用偏光显微镜、荧光显微镜和冷热台对大乌尔根尖子山剖面和地质浅井早白垩世上库力组的泥灰岩样品进行了系统研究。

In practical study, the essential flow is""on the basis of the study of the faults, strata denuded thickness and original thickness, analyzing the controlling effect of the faults to the sedimentation and denudation, and combined with the areal geology background, reconstructing the basin prototype of each stage"". 2. As the basic theories and methods of the calculation of the denuded thickness, such as, the methods of cosmogenic nuclides, wave equation, apatite fission track, structural sections, acoustic wave, vitrinite reflection, etc, were argued detailedly , and their applicable ranges were analyzed , the denuded strata thickness of each structural layer layer of pre-Tertiary was reconstructed.

对宇宙成因核素法、波动方程法、裂变径迹分析法、构造横剖面法、声波时差法、镜质体反射率法等计算剥蚀量方法的基本原理进行充分论证、改进，分析了各方法的适用范围，在此基础上，综合充分运用上述方法，计算了济阳坳陷前第三系各构造层在不同时期的剥蚀量，绘制了中生代时期古生界顶面的地层剥蚀量等值线图、新生代时期古生界顶面的地层剥蚀量等值线图、白垩纪沉积时侏罗系剥蚀等值线图、新生代沉积期白垩系剥蚀等值线图、新生代沉积期侏罗系剥蚀等值线图等图件，并通过对古生界地层的热变质程度分析，确定了有1500～2000m的早、中三叠世的原始沉积地层在晚三叠世被剥蚀殆尽。3。
