此文介绍了华北台型永夏煤田石炭系、二叠系的含煤建造特点;论述了物探测井在煤田地质工作中的作用:分析了不同沉积环境的测井曲线形态标志。该区石炭系含煤1—3层,均不可采;二叠系二煤组二。煤为本区主要可采煤层,平均厚度达2米以上,属中厚层煤;三煤组主要可采煤层3—5层,可采厚度达5米以上。区内天然焦变质强,茴村以北二煤组常变为半焦、天然焦;以南二煤组稳定、发育。对白炭(?)二叠纪沉积环境的分析,主要是根据测井曲线形态及岩性组合特征来进行的。不同时期不同的沉积环境的沉积岩系其测井参数是不同的,二叠(?)区内以松塔型、箱型曲线形态为主要特征而不同于石炭纪的沉积环境。由于早二叠世处于平原三角洲地带,在二_2煤形成时物源较丰富,具有得天独厚的优越条件,因而二_2煤在本区较为发育。总之,据本区的沉积特点,所选测井曲线形态标志是易于判别出不同时期的沉积环境的;对沉积环境的分析依据是可靠的。 This paper introduces the coal-bearing features of Carboniferous and Permian coalfields in the Yongxia coalfield, North China, and discusses the role of geophysical logging in the geological work of coalfields. The logarithmic signs of different logging environments are analyzed. Carboniferous coal-bearing areas in the area 1-3, are not allowed to take; Permian II coal two. Coal is the main recoverable coal seam in this area, with an average thickness of over 2 meters, which belongs to middle-thick coal. The main coal seam of the third coal seam is 3-5 stories and the recoverable thickness is more than 5 meters. The natural coking metamorphism is strong in the area, and the second coal group in Fenghuang Village often changes into semi-coke and natural coke; the second coal group in South China is stable and developed. The Permian sedimentary environment analysis of the white carbon (?) Is mainly based on the well logging curve morphology and lithology combination characteristics. Sedimentary parameters of sedimentary rocks with different depositional environments are different in different periods. In the Permian (?) Region, there are pine towers and box-shaped curves, which are different from the sedimentary environment of Carboniferous. As the Early Permian in the plain delta, in the two _2 coal formation is rich in resources, with unique advantages, so two _2 coal in this area more developed. In short, according to the sedimentary characteristics of this area, the selected logging curve shape sign is easy to distinguish the sedimentary environment of different periods; the analysis of sedimentary environment is reliable.
