渤中25-1油田储层敏感性试验研究

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。

Experimental Study on Reservoir Sensitivity of Bozhong25-1 Oilfield

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 coeff...
