摘　　要：在固井施工过程中,受到井眼自身形状以及所采用的水泥浆和钻井液性能差异的影响,常常会出现水泥浆和钻井液混合的情况,从而造成严重的接触污染问题。在复杂的井下水泥浆施工环境中,这类接触污染作用会给实际操作带来十分不利的影响,因此相关部门必须要对这类问题引起重视,不仅要明确水泥浆和钻井液接触污染的具体表现,也需要采取有效的处理策略,降低给生产和施工所带来的危害。In the process of cementing construction,due to the different shape of the well eye and the difference between the cement slurry and drilling fluid,often appear,resulting in serious contact pollution problems. In the complex underground cement slurry construction environment,this kind of contact pollution will bring very adverse effects to the actual operation,so the relevant departments must pay attention to this kind of problem,not only to clarify the concrete performance of cement slurry and drilling fluid contact pollution,also need to take effective treatment strategy,reduce the harm brought to the production and construction.
