摘　　要：YLD-1油水井堵漏剂是在胶结界面微观结构研究的基础上,依据界面胶结强度的增强机理和方法开发出的一种新型油水井化学堵剂。与常规堵剂相比,YLD-1化学堵剂具有3个突出的特点:1)进入封堵目标层后能快速形成牢固的网架结构而有效地驻留在漏失层中;2)能在目标封堵层形成抗窜强度高、耐冲蚀的封堵层;3)在井筒内的YLD-1化学堵剂在较长时间内能保证有良好的流动性,不会沉淀和凝固,而堵浆一旦进入封堵目标层就能快速形成结构和强度。重点分析了YLD-1油水井化学堵剂的特点,并介绍了其在现场各种复杂井中的推广应用情况。The new type of chemical sealing agent named YLD-1 suited for oil and water injection wells is developed based on the mechanisms and method of strengthening the interface bonding strength on conditions of fluid seeping. Compared with routine additives, this material is able to: form web structure rapidly after entering target zones for blocking and stay in the target zone effectively; establish firm sealing zone resistant to erosions in aim formations; maintain good fluidity without sediments and solidifications. This paper analyses principally the properties of the new additive, and presents its field popularizations in complex wells.
