摘要
本文重点讨论了松辽盆地三肇地区低渗透油层损害的评价指标,提出了油层的速敏、水敏、酸敏及泥浆损害的分类评价标准。在此基础上评价了三肇地区扶、杨油层的敏感性矿物分布特征及油层损害的潜在影响因素,为防止油层损害,制定合理的施工方案提供了地质依据。
This paper mainly discussea the evaluation index of low permeability reservoir damge of Sanzhao area in Songliao basin. The classifica-tion evaluation criteria of speed, water and acid sensitivity and mud damage to the reservoir are put forward. Based on the above, the distribution char-ecteristics of sensitive minerals of Fuyu, Yangdachengzi reservoirs in Sanzhao area and the potential effecting factors are evaluated. Geologic basis is porvided in designing a reasonable operation project for preventing the reservoir from being damaged.
