| 摘 要： | 通过岩心流动等实验，分析了杏南开发区表外储层的敏感性及产生敏感性的原因。结果表明，表外储层呈中等偏弱～中等偏强水敏；对HCI呈中等偏弱酸敏；中等偏弱速敏，临界流速大于11．95m／d；中等偏弱碱敏，临界pH值为7．5。储层泥质含量高是造成敏感性的主要原因，建议注水开发及作业时进行工作液的筛选研究。

| Abstract: | Through experiments, such as core flow, the sensitivities of the Biaowai reservoir in Xing- nan development zone and its causes are studied. The results show that the sensitivity properties of Biaowaireservoir are medium water sensitivity, medium or slightly low acid sensitivity to HC1, medium or slightly low velocity sensitivity with a critical velocity of over 11.95m/d, medium or slightly low alkali sensitivity with a critical pH value of 7.5. The high content of shale in the reservoir is the main cause leading to the sensitivities, and it is advised that the working fluid should be selected when water injection development and operation are carried out. |
