| 摘 要： | 在充分调研国内外沥青质沉积资料的基础上，对沥青质的物理化学沉积机理、沥青质堵塞储层孔喉的机理进行了总结。在对比分析的基础上，将沥青沉积模型划分为基于相劈分的沥青质沉积模型及基于胶体不稳定性的沥青质沉积理论模型，指出了各模型的局限性及其存在根源。通过分析原油中沥青质发生絮凝的温度、压力、组分，可以找出发生沥青质沉积的主要影响因素，从而搞清沥青质对储层渗透率的影响，为油藏注气开发方案设计提供依据，对防止储层损害,确保稳产、高产具有重要意义。

| Abstract: | Based on the investigation of comprehensive literatures about asphaltene deposition, the physical and chemical deposition mechanism of asphaltene and its plug to pore and throat are summarized. After being compared and analyzed, asphaltene deposition models can be classified as the ones based on phase splitting and colloid instability. Their limitedness and the cause are pointed out. It is indicated that it is necessary to analyze the temperature, pressure and components of asphaltene flocculation, to find out the main reason of asphaltene deposition and then clarify the influence of asphaltene on reservoir permeability, which can provide the basis of reservoir development plan, prevent formation damage and insure steady and high yield. |
