摘要
沥青垫是富含沥青质的石油带。它的存在使得孔渗性较好的储集层成为油气藏中的有机隔层,降低油藏质量与油藏规模,增大了油藏的开发难度。本文通过采用储层热解分析技术手段认清了沥青垫的组分特征,并采用重轻比与PI_3指数将沥青垫、高阻层及油层的技术界限进行划分。证明储层热解分析能够在沥青垫的识别中提供重要的技术保证。
Tar mat is rich in the asphaltenes of oil zone. It makes good reservoir pore permeability reservoirs of the organic interlayer. Therefore, tar mat can lower the quality of reservoir and increase the reservoir development difficulty. In this paper, through the adoption of reservoir pyrolysis analysis technology to identify the composition characteristics of the tar mat. Using the weight of light ratio and PI3 index to divide tar mat, high resistance layer and the oil layer. Proving that reservoir pyrolysis analysis can provide important technical guarantee for the identification of tar mat.
