摘　　要：为解决深层高温固井施工中水泥浆与钻井液相互接触污染,以及高温对隔离液及配套处理剂的影响问题,从而研制出一种相容性良好、抗180℃高温的固井水基隔离液体系,并对其性能进行了评价。室内实验结果及现场应用效果表明,该水基隔离液体系在180℃下具有良好的高温稳定性、流变性稳定,确保了深层油气井的固井施工安全。A new kind of water based spacer fluid that can be used at 180℃ is optimized and synthesized,aiming at providing a solution to the mutual pollution of drilling fluids and cement slurries in deep and high temperature cementing operation.Laboratory evaluation and field application of 7 wells show that this spacer fluid has good stability,anti-pollution and rheology performances at temperature 180℃,and improves the quality of cementing operation.
