摘要
利用渤中25-1油田的油层取心岩样,按照我国石油天然气行业有关标准,试验研究了渤中25-1油田储层岩石的流速敏感性、水敏性、盐敏性、碱敏性和酸敏性。研究结果表明,渤中25-1油田储层岩样速敏损害指数为0.176～0.206,速敏损害程度弱;岩样的水敏损害指数为0.665～0.723,水敏损害程度中等偏强至强水敏,岩样的碱敏损害指数为0.248～0.263,碱敏损害程度弱,岩样的盐酸酸敏损害指数为0.250～0.293,具有弱酸敏。为油田的合理开采提供了依据。
According to the standard concerning oil and gas industry in China, the flow velocity sensitivity, water sensitivity, salt sensitivity, alkaline sensitivity and acid sensitivity of Bozhong 25-1 Oilfield were tested by using core sample of Bozhong 25-1 Oilfield. The result shows the damage coefficient of rock sample velocity sensitivity was 0.176~0.206, velocity sensitivity damage was weak. Water sensitivity coefficient was 0.665~0.723, its damage level was from mid-high to strong. Alkaline sensitivity coefficient was 0.248~0.263, its damage was weak. Salt and acid sensitivity coefficient was 0.250~0.293, its acid sensitivity was weak. A basis is provided for rational oilfield development.
