【摘要】：油页岩作为一种非常规能源,储量巨大,其综合开发利用日益受到重视。铜川马泉地区位于鄂尔多斯盆地陕北斜坡东南部,铜川矿区之北部,油页岩位于铜川组顶部,埋藏较浅,厚度变化较大。本文主要通过分析研究地质、测井、化验分析等资料进行基础研究,得到如下认识:(1)通过钻探、测井等资料多方法对比分析,将区内5层油页岩分别编号为0、1上、1、2、3号。其中,1号油页岩厚度较大,分布广泛,较为稳定。(2)研究区测井资料分析对比得到,油页岩测井曲线组合识别特征为“三高一低”,即高电阻率(GR01)、高自然伽马(NG01)、高声波时差(SON2)、低密度(DENB)。对电阻率、自然伽马等物性参数分别与含油率进行相关性分析,结果表明,各参数与含油率关系密切,具有一定的地球物理意义。(3)研究区油页岩灰分含量高,低挥发分,发热量低,含油率4-7%,属中品级油页岩,其干酪根类型为Ⅰ型和Ⅱ1型,且以Ⅱ1为主。(4)根据一般工业指标(参照《矿产资源工业要求手册》),对含油率≥4%的油页岩进行资源量估算,共获得资源量12736万吨。通过本次研究,查明铜川马泉地区油页岩区域构造、物性特征、分布规律,并估算资源量等,为研究区油页岩的进一步勘探开发提供可靠的依据。
[Abstract]:As a kind of unconventional energy, oil shale has huge reserves, and its comprehensive development and utilization are paid more and more attention. The Maquan area of Tongchuan is located in the southeast of Shanbei slope in Ordos Basin, the northern part of Tongchuan mining area, and the oil shale is located at the top of Tongchuan formation. This article mainly through the analysis and research geology, the logging, the laboratory analysis and so on data carries on the basic research, obtains the following understanding: 1) through the drilling, the logging and so on data many methods contrast analysis, The five layers of oil shale in this area are numbered 0 1, 1, 1, 2, 3 respectively. Among them, 1 oil shale is relatively thick, widely distributed and relatively stable. 2) the well logging data of the study area are analyzed and compared. The recognition characteristics of oil shale logging curve combination are "three high and one low", that is, high resistivity gr 01g, high natural gamma NG01g, high sonic time difference so N 2, low density DENBN. The correlation analysis between resistivity, natural gamma and other physical parameters and oil content is carried out, and the results show that, Each parameter is closely related to oil content and has a certain geophysical significance.) the oil shale has high ash content, low volatilization, low calorific value and oil content 4-7. It belongs to middle grade oil shale and its kerogen types are type 鈪，
