| 摘 要： | 在系统分析油基钻井液对致密储层损害机理后,以西北A区致密低渗透砂岩为研究对象,确定了固相颗粒堵塞和水锁是油基钻井液对储层主要的损害,在此基础上,提出了储层保护钻井液的优化措施。

| Abstract: | After systematically analyzing the damage mechanism of oil-based drilling fluid to tight reservoir,it is determined that solid-phase particle plugging and water lock are the main damages of oil-based drilling fluid to reservoir in A block. On this basis,the optimization measures for reservoir protection drilling fluid are proposed. |
