摘要
针对锦45断块注水压力高、油井出砂严重、酸化短期效应等现状,通过对该区块四个油层组的地质资料分析,利用室内配伍性评价手段,评价该区块储层自身的敏感性及蒸汽冷凝水对储层的损害类型和损害程度,认为该储层是一个弱速敏、水敏中等、弱碱敏的储层;通过岩心损害率实验发现,蒸汽冷凝水对该储层的损害较大。根据以上结论提出了有针对性的措施和建议。
In view of current situation in block Jin 45, that is high water injection pressure, serious sand production, and short validity of acidizing, this paper analyzes geologic data of four oil zones, and evaluates compatibility, reservoir sensitivity, and damage of vapor condensed water to reservoir. It is thought that this reservoir is slightly velocity sensitive, moderate water sensitive, and slightly alkali sensitive. Test of core damage rate shows that, vapor condensed water is very harmful to this reservoir. Corresponding measures and suggestions are provided.
