根据大量的实验,筛选出一种新型的油井水泥降失水剂,其失水量、流变性、稠化时间、强度等性能较好,能满足固井要求。在大港油田固井2口,取得较好的固井效果。 According to a large number of experiments, a new type of oil well cement fluid loss agent was screened out. Its performance of fluid loss, rheology, thickening time and strength is good, which can meet the cementing requirements. In Dagang oilfield cementing 2, get better cementing effect.
