摘要:
中扬子地区上奥陶统-下志留统五峰组-龙马溪组页岩在纵向上具有较强的非均质性, 影响着页岩储层含气性以及后期的可压裂性。本研究综合测井曲线、钻井岩心、薄片观察、有机碳测试、X衍射矿物测试以及主微量元素测试, 在建立研究区页岩等时地层层序格架的基础上, 剖析该套页岩在有机质丰度、矿物组分、页岩岩相等方面的非均质性特征, 结合恢复的古气候和古环境信息, 揭示控制非均质性的主控因素。研究结果表明: 五峰组-龙马溪组一段页岩识别出2个三级层序, 其中五峰组划分出海侵体系域(TST1)和高位体系域(HST), 龙马溪组一段划分出海侵体系域(TST2)和早期高位体系域(EHST)。海侵期页岩硅质含量高, 黏土含量较低, 有机碳含量高, 主要发育硅质页岩相和含黏土硅质页岩相; 早期高位域期, 页岩发育粉砂质条带和透镜状层理, 黏土含量较高, 有机碳含量较低, 主要发育含硅黏土质页岩相。古气候指标(CIA、Rb/Sr)、古生产力指标(Cu/Al、P/Al)、氧化还原条件指标(MoEF、UEF)以及陆源输入(Ti)指标在垂向上的变化表明研究区在海侵期具有较高古生产力, 缺氧的沉积环境、低陆源输入以及相对干燥寒冷的气候条件, 而高位体系域期, 研究区表现为古生产力较低、弱还原-氧化的沉积环境、高陆源输入以及相对温暖潮湿的气候条件。火山活动、底流作用、古气候、古生产力、氧化还原条件以及陆源输入是研究区五峰组-龙马溪一段页岩纵向非均质性的主控因素。最后通过与上扬子地区页岩层段参数对比, 发现研究区主要具有埋藏深度较深、富机质页岩层段明显偏薄、含气量偏低, 脆性矿物含量偏多等特征。
Abstract:The Upper Ordovician-Lower Silurian Wufeng-Longmaxi shales in the Middle Yangtze area have strong vertical heterogeneity, affecting the gas-bearing capacity of shale reservoirs and the fracturing ability.This study integrates wire-line logs, drilling cores, thin section observations, total organic carbon content, X-ray diffraction mineralogy measurement, and major, trace elements measurement.Under the stratigraphic sequence framework in the study area, the vertical variation of TOC content, mineralogical composition and shale lithofacies were studied.Combined with geochemical proxies for paleoclimate and paleoenvironmental conditions, the main factors controlling vertical heterogeneity were discussed.The results show that the Wufeng-Longmaxi shales have two 3rd-order sequences.The Wufeng Formation is divided into the transgressive systems tract(TST1) and high stand systems tract(HST), and the Longmaxi Formation is divided into the transgressive systems tract(TST2) and the early high stand systems tract(EHST).During the transgression period, the shale has high silica content, low clay content, and high organic carbon content, and mainly developed siliceous shale facies and clay-bearing siliceous shale facies.In the early high-stand systems tract period, shale developed silty bands and lenticular bedding, with high clay content, and low organic carbon content, and mainly developed siliceous-clay mixed shale lithofacies.The vertical changes of paleoclimate indicators(CIA, Rb/Sr), paleo-productivity indicators(Cu/Al, P/Al), redox environmental indicators(MoEF, UEF), and terrestrial input(Ti, Zr) indicators indicate a high productivity, anoxic sedimentary environment, low terrestrial input and relatively dry and cold climate conditions for the transgression period, while during the high-stand systems tract deposition, the study area has low productivity, oxic-dysoxic environment, high terrestrial input and relatively warm and humid climateconditions.The paleo climate, paleo productivity, redox conditions, volcanic activity, terrestrial input and bottom currents are the main factors controlling the stratigraphic heterogeneity of the Wufeng-Longmaxi shales in the study area.Finally, by comparing with some parameters of the shale in the Upper Yangtze region, it is found that the study area shows the differences in deeper burial depth, thinner organic shale, lower gas content and more brittle mineral content.
