摘　　要：采用室内岩心实验的方法,对西非G断块进行了储层速敏、水敏、碱敏、酸敏等敏感性评价。实验结果表明,该储层的速敏损害程度弱,水敏损害程度中等偏弱,具有中等偏弱碱敏和强酸敏效应。储层敏感性实验研究结果对西非G断块合理制定开发技术及作业等提供参考。By using the method of indoor core experiment,the reservoir velocity sensitivity,water sensitivity,alkali sensitivity and acid sensitivity of G fault block in West Africa are evaluated.The experimental results show that the degree of velocity-sensitive damage of the reservoir is weak,the degree of water-sensitive damage is moderately weak,and it has moderately weak alkali-sensitive and strong acid-sensitive effects.The experimental results of reservoir sensitivity provide a reference for the reasonable formulation of development technology and operation of G fault block in West Africa.
