摘要
为了解决塔河油田三开固井质量不理想的难题 ,开发出以硅藻土—微硅为复合减轻剂 ,SY为高温稳定早强剂的LDHS水泥浆体系。该体系具有密度低、强度高、流变性好、与外加剂配伍好、地面与井下密度一致、施工简便等优点。在塔河油田S70井进行现场应用 ,固井质量达到了优良标准 ,实现了低密度水泥浆在塔河油田固井质量的突破。
In order to solve the knotty problem of poor cementing quality in Tahe Oilfield,LDHS cement slurry system is developed.The system has many features,such as low density,high strength,good rheology,good compatibility with other additive and simple construction etc..Through field application of LDHS cement slurry system in well S70 of Tahe Oilfield,good cementing quality is got.
