     The greater the grinding depth, the larger the hardness when using 400# belt, but the hardness stress using 36# belt is larger than the hardness using 400# belt. ⑤The micro-organization of 0Cr17Ni4Cu4Nb steel do not change after grinding .
     细粒度砂带磨削0Cr17Ni4Cu4Nb钢时随着磨削深度增加,硬度值不断增大,由于粒度变细,其硬度值较粗粒度砂带砂带磨削0Cr17Ni4Cu4Nb钢时要小,同时它并不存在粗粒度砂带磨削0Cr17Ni4Cu4Nb钢在增加磨削深度后,硬度值变小的情况。

In May 1981 in Paipu commune of the county of Zuan, Hainan Island, Guangdong province, late Pleistocene dolomite has been discovered in the intertidal regine on the abrasion flat. It was confirmed as a sandy dolomite by the identifications of thin section, scanning electron microscopy, staining techniques, X-ray diffraction techniques and thermocouple analysis. This dolomite is euhedral rhombic form of very finely crystalline(6-18μ)with zonal texture. More iron substitutes for magnesium in the dolomite lattice...

In May 1981 in Paipu commune of the county of Zuan, Hainan Island, Guangdong province, late Pleistocene dolomite has been discovered in the intertidal regine on the abrasion flat. It was confirmed as a sandy dolomite by the identifications of thin section, scanning electron microscopy, staining techniques, X-ray diffraction techniques and thermocouple analysis. This dolomite is euhedral rhombic form of very finely crystalline(6-18μ)with zonal texture. More iron substitutes for magnesium in the dolomite lattice to form solid-solution; the clastic grains in the rock consist of 20-25%.Pleistocene dolomite of Paipu, Hainam Island is of replacement origin. It occurs in Pleistocene sandy and rubbly sediments as a abrasion terrace in the intertidal zone and in environments of mixture of subsurface water with marine salty water and with intermittent subaerial exposure resulting from tides. The discovery of intertidal sandy dolomite would enrich the types and diagenesis of Quaternary dolomite. It has important role in the interpretation of formation of old dolomite.

1981年5月于广东省海南岛儋县排浦公社首次发现珊瑚岸礁海蚀坪潮间带的更新世白云岩.经薄片、扫描电镜、染色、差热和X光衍射等分析鉴定,确认它是砂质白云岩.白云石为菱形极细晶,具环带构造;有较多的Fe~(++)取代Mg~(++)形成类质同象.岩石中石英和岩屑约占20—25%. 海南岛排浦更新世白云岩是在海蚀坪潮间带,更新世砂砾质沉积物中,由海水蒸发,渗透回流,以及淡水与海水或粒间水混合的变盐度的局部还原环境中形成的交代白云岩。这种潮间带的砂质白云岩的发现,丰富了第四纪白云岩的类型和成岩环境,对古代白云岩成因的解释具有重要意义.

Abstract

本文通过分析姚一段北安-杏树岗三角洲,提出湖进三角洲的概念,其沉积层序为三层结构的正旋回组合,在湖进过程中,三角洲体随湖岸线向陆地方向迁移,层位由老变新。湖进三角洲的骨架砂体呈指状展布,砂体的分布模式是:河口堆积砂体——水下分流河道条带砂体——分流间透镜砂体——席状砂体,而主骨架砂体是分流条带砂体。

ABSTRACT

本文综合了近年来对松辽盆地(重点是北部地区)石油地质研究的成果,将主要的认识进行了总结,包括白垩系为陆相沉积的论证、盆地的性质和演化阶段、中新生界的构造特征、陆相生油的主要特征和油气形成阶段、大型湖盆的沉积特征和各种相带的砂体形态、粘土矿物的纵向演化规律和成岩阶段等,最后总结了控制油气聚集的基本规律,指出松辽盆地不仅存在着比较简单的背斜构造油气藏,而且也存在着多种比较复杂的油气藏。
