中文摘要: 页岩气是一种潜力巨大的非常规油气资源,受到世界各国越来越多的关注,页岩气研究成为热点课题。岩石物理学作为地震、测井等油气勘探手段的基础,在页岩气研究中必然起到非常关键的作用。本项目拟收集中国西南地区页岩气钻探的岩样、测井等资料,以页岩气储层岩样为主要研究对象,开展声学性质、电性、核磁共振和自然伽马能谱等岩石物理实验测量,获取页岩纵横波速度、密度、电阻率、阳离子交换容量、核磁共振、伽马能谱等各种参数,辅以孔渗、铸体薄片、X-衍射等实验结果,考察储层岩性及其所含流体性质与各种岩石物理性质的关系,探索含气页岩储层的岩石物理特性规律;基于岩石弹性理论和介质模型,研究储层参数与地震属性参数的关系,为页岩气储层地震识别提供依据;开展页岩导电机理研究、核磁共振和伽马能谱特征研究,为页岩气储层测井解释模型的建立奠定基础。本项研究既能满足目前中国页岩气潜力调查的实际需要,也能促进岩石物理学应用领域的发展。

英文摘要: Shale gas is an unconventional gas resource of great potential, and it draws more and more attention all over the world. Therefore, the research of shale gas has become a hot spot. As the basic of seismics, well logging and other hydrocarbon exploration techniques, petrophysics is the key in the research of shale gas.In this project, samples and well logging data of shale gas drilling explorations in the Southwest China will be collected, and the samples of shale gas reservoirs will be the main research object. The petrophysical experiments including acoustical properties, electrical properties, Nuclear Magnetic Resonance (NMR), Natural Gamma-ray Spectral (NGS) will be developed, through which we can obtain the parameters such as P/S wave velocities, density, resistivity, Caion Exchange Capacity (CEC), NMR, NGS. Additional experimental results including porosity and permeability, casting thin section, X-diffraction will be obtained. All the experimental results will be used to invesigate the petrophysical properties' law of shale, and the influence of lithology, porosity and permeability. How the variations of reservoirs' physical properties effect the P/S wave velocities and wave impedance will be analyzed to provide evidences for seismic identifications of shale gas reservoirs. The study on the characters of e
