摘要

    摘要
  • 摘要: 为了评价豫东地区煤系烃源岩生烃潜力，基于有机碳含量（TOC）、镜质体反射率、干酪根类型及显微组成等测试分析结果，探讨了豫东地区不同区块煤系烃源岩的有机地球化学特征，对比分析了不同区块煤系气资源潜力，提出煤系气勘探有利区块。结果表明：区内煤系烃源岩的有机碳含量偏低（小于1.5%）；干酪根类型以Ⅲ型为主，偶见Ⅱ2型干酪根，利于生气；煤系经历了中二叠-中晚三叠世和晚侏罗-早白垩世2个大量生烃阶段，烃源岩热演化程度较高，镜质体反射率（Rran）为1.44%~3.80%，平均2.83%，有机质进入高成熟-过高成熟阶段，生烃量较充足。总体上，区内烃源岩生烃潜力属于差-中级别，砂泥岩储集性能相对较好，含气量高。煤系盖层主要为封盖性好的细砂岩、煤层、泥质岩类，煤系烃源岩气体保存条件好。研究认为研究区的睢西区块烃源岩具有埋藏深度较浅、有效厚度大、孔隙度高、含气量和含气饱和度高、有机质成熟度高的特点，为豫东煤系气勘探的有利区块。
    Abstract: In order to evaluate the hydrocarbon generation potential of coal-measure source rocks in eastern Henan Province, based on the measurement results of organic carbon content, vitrinite reflectance and the identification of maceral and type of kerogen in source rocks, the organic geochemical characteristics and the resource potential of coal-measure gas in different blocks of eastern Henan Province were comprehensively analyzed, and favorable blocks for coal-measure gas exploration were designated. The results show that the organic carbon mass fraction of coal-measure source rocks presents low as a whole(less than 1.5%). Kerogen in coal-measures source rocks is mainly of type Ⅲ and Ⅱ2 can be locally seen in the source rocks, so it can be concluded the source rocks are favorable for hydrocarbon generation. The coal-measure strata has undergone twice mass hydrocarbon generation stage(Middle Permian to Middle-Late Triassic and Late Jurassic to Early Cretaceous), the thermal evolution extent of source rocks is relatively high. The vitrinite reflectance ranges from 1.44% to 3.80% and 2.83% in average, so the organic matter is classified form the high mature to over high mature stage, hydrocarbon generation is adequate. As a whole, the hydrocarbon generation potential of source rocks in the area belongs to bad-medium standard, sandstone and mudstone reservoir property is relatively good, gas content is high. The coal measures are mainly fine sandstone, coal seam, mudstone with good sealing property, which have good preservation conditions. The study shows that the hydrocarbon source rocks in Suixi block are characterized by shallow burial depth, large effective thickness, high porosity, high gas content and high gas saturation, high maturity of organic matter, are favorable blocks for the exploration of coal-measure gas in eastern Henan Province.
