| 摘 要： | 吉林油田在储层敏感性评价的基础上,室内进行了现场二开钻井液体系的损害评价实验。结果表明,现场二开钻井液体系对乾安地区低渗透砂岩储层的损害程度为34.52%,以液相损害为主,并且存在严重的水锁损害。因此,减轻低渗透砂岩储层的损害程度重点是控制钻井液滤液侵入。根据d90暂堵理论及防水锁技术对现场二开钻井液体系进行了优化,加入屏蔽暂堵剂后的钻井液对岩心的损害程度降低了16.25%,优选的新型防水锁剂可使钻井液对岩心损害程度减少5%左右,能够有效保护低渗透砂岩储层。

| Abstract: | Impairment evaluation of drilling fluid system for the second spud in Jilin Oilfield has been conducted through laboratory experiment based on reservoir sensitivity evaluation.Experiment result indicates that the damage degree of the second spud drilling fluid system to the low permeability sandstone reservoirs in the Qian'an area is 34.52%,with liquid phase damage being the dominant and there is also severe water blocking damage.The key to reducing the damage is to control the invasion of drilling fluid fi... |
