| 摘 要： | 根据对涠洲11-1-A1井的油层物性、储层特征及敏感性分析，采用醇基酸作为酸化施工主处理液，这样既减少了对开发层位的损害，又保证了处理液对地层有适宜的、较高的溶蚀率，对解除钻井液和固井水泥浆造成的污染堵塞具有明显效果。经过酸液类型及浓度的确定、添加剂的筛选、流动模拟及残酸分析等室内试验研究，确定了适用于该井海上酸化的酸液配方。

| Abstract: | Based on the reservoir characteristics and sensibility analysis of Weizhou11-1-A1 well, alcoholbase acid is used in accordance with the practical condition of pay zone in the offshore oilfield. The compound acid has less damage and better suitable dissolving capacity to formation. It has remarkable effects on plug removing induced by drilling fluid and cement liquid. The alcohol-base acid for Weizhou11-1-A1 well is developed after experiment of selecting the type, concentration of acid and additives and analyzing reacted acid. |
