摘要:

天然气水合物是一种新的非常规清洁能源,一直受到各国的重视.近期我国在南海天然气水合物地质调查和开采中取得突破性进展,使得天然气水合物在国际能源中的重要性更加突出.为促进我国天然气水合物测井评价的发展,本文在前人研究的基础上,通过对南海神狐海域的天然气水合物资料进行调研,结合国内外对天然气水合物的研究,从三个方面展开对天然气水合物的论述:首先介绍了天然气水合物三种常见的晶格结构、四种宏观分布形式及六种赋存模型;然后根据南海神狐海域地质特征,总结了南海神狐海域含天然气水合物层的测井响应规律特征;最后基于不同的岩石物理模型、测井数据和模拟实验,对天然气水合物储层的孔隙度和饱和度等物性参数进行定量评价.本文详细地综述了天然气水合物及其储层参数的地球物理测井方法,为天然气水合物的深入研究提供帮助.

Abstract:

Natural gas hydrate, as a new unconventional energy source, has been paid much attention all over the world. Recently, China has made a breakthrough in the geological survey and exploitation of natural gas hydrate in the South China Sea, making natural gas hydrate more important in international energy. In order to promote the development of Chinese natural gas hydrate logging evaluation, based on the previous studies, this paper studies the natural gas hydrate data of Shenhu area in the South China Sea, and discusses the natural gas hydrate from three aspects in combination with domestic and foreign research on gas hydrate. Firstly, this paper introduces three common lattice structures, and four macroscopic distributions, and six occurrence models of natural gas hydrate. Then, the logging response characteristics of natural gas hydrate formation are conducted resulting from the geological characteristics of Shenhu area in the South China Sea. And last, based on different petrophysical models, logging data and simulation experiments, the physical parameters such as porosity and saturation of natural gas hydrate reservoirs are quantitatively evaluated. In this paper, geophysical logging methods for natural gas hydrate and its reservoir parameters are reviewed in detail, which is helpful for the further study of natural gas hydrate.

Key words: natural gas hydrate, geophysical well logging, reservoir parameters evaluation, petrophysical models
