摘　　要：柴达木盆地西部发育着储集物性好、分布广泛、储量规模较大的生物礁储层。根据国内外生物礁的分类标准,对野外勘查、岩心和测井资料的分析表明,柴达木盆地西部生物礁主要为藻礁、叠层石礁和凝块石礁。根据目前国内外生物礁研究的最新成果及柴达木盆地的区域构造和沉积特点,揭示了柴达木盆地西部影响生物礁生长的构造、沉积和环境因素,总结了生物礁在柴达木盆地西部的分布规律,提出了下步生物礁储层勘探时应该遵循的原则和方法,为油田类似储层的勘探和开发提供了参考资料。Abundant and widely distributed reef reservoirs with extraordinary property and conspicuous reserves were found in the western Qaidam Basin, According to the reef classification criteria at home and abroad, the reef in Qaidam Basin can be classified into three main types including algal, stromatoliteand thrombolite reefs by means of the field survey, core and logging analyses, According to the present reef study at home and abroad, the tectonic, depositional and environmental factors influencing the reef development were revealed. The vertical and lateral distribution of the reef and depositional characteristics in Qaidam Basin was furthermore analyzed, The methods and principles that should be followed in the exploration of reef reservoir were proposed.
