摘要
近年大量的勘探与研究成果表明,中国南海海域具有良好的水合物资源前景。根据所掌握的勘探资料,尝试利用“概率统计法”对南海海域水合物资源前景进行了初步预测,在50%概率的条件下,南海海域的水合物资源量约为649.68×1011m3,与众多学者对全球天然气水合物资源量的估算相似。由于目前勘探程度较低和很多评价参数不能准确给定,因此对南海海域天然气水合物资源量的估算是初步的。该项研究旨在探索天然气水合物资源量的评估方法,随着勘探、研究程度的深入和评价资料的增多,水合物资源量的评价精度将会得到进一步的提高。
A great deal of recent exploration and research data show that the South China Sea has good prospects of gas hydrate resources. According to the exploration data available, an attempt has been made to use the probability statistic method to estimate the resources of gas hydrates in the sea area. The resource of gas hydrates in the South China Sea is approximately 649.68×10^11m^3 at a 50% probability, which is similar to the estimate of the global resource of gas hydrates. As the area is underexplored and many appraisal parameters cannot be given accurately at present, the figure is only a preliminary estimate. The main purpose of this study is to explore the estimate method of gas hydrates. With the deepening of exploration and research and increase of the appraisal data, the estimate precision of gas hydrate resources will be further improved.
