摘　　要：石油是全球最主要的化石能源之一,其被称为工业的血液。在石油钻井开采过程中可能发生各种井下复杂情况,其中井漏则是一种常见的井下事故。统计川东北地区,油田处理井漏所花去时间占到总钻井时间的10%左右^([1]),严重影响了钻井安全和钻井速度,严重增加了钻井成本。化学堵漏剂在石油钻井中的应用有效降低了井漏事故和井漏处理成本。本文介绍了化学堵漏剂的研发历史以及目前化学堵漏剂的研发方向和重点,总结了目前化学堵漏剂的应用范围,对化学堵漏剂的研发提出几点意见。Oil is one of the world＇s most important fossil energy, which is called the blood of industry. It may occurs all the complicated downhole conditions during drilling, such as leakage. According to the statistics in the northeast of Sichuan, the time of preventing and dealing with lost circulation is wasted and makes uplO% of the total drilling time. It seriously affected the safety drilling and the drilling speed, at the same time increased the cost of drilling. Chemical plugging agent can effectively leak stoppage and prevent to leak in the petroleum drilling, The paper presents the application effect of various chemical LCM in different regions and different oil fields. It will help that the leakage successfully is prevented.
