摘要
应用岩心流动实验评价了中原油田沙二储层的敏感性,分析了储层潜在伤害因素、伤害机理及伤害程度。结果表明,该油藏的速敏损害程度弱,水敏损害程度弱,同时具有弱至中等偏弱碱敏和弱酸敏效应。并根据评价结果对油田开发工作提出了具体建议。
Core flaw test is applied to evaluate reservoir sensitivity in the shaer reservoir on zhongyuan field,the factors, mechanism and degree of potential reservoir damage are studied. And the results show that the damage degree of velocity sensitivity is weak in this reservoir, and its damage degree of water sensitivity is weak, and at the same time this reservoir is damaged owing to the low acid sensitivity and the middling weak arkali sensitivity. Based on the evaluation results,some special suggestions have been proposed for development of the field.
