摘　　要：通过室内试验研究的新型海水水泥浆在渤海油田油层套管固井中得到成功应用。应用结果表明,新型海水水泥浆能够满足中深部地层(2000m左右)固井作业的要求,作业安全可靠,固井质量优良,对储层的伤害低于淡水水泥浆。新型海水水泥浆的成功应用,打破了以往海上技术套管和油层套管固井作业只能依赖淡水的限制。在海上钻井作业中广泛应用新型海水水泥浆,能够取得良好的社会效益和经济效益。A new kind of seawater cement slurry has been studied through Lab test and has been used in pay zone casing cementing in Bohai oilfield success fully. The application results indicate that this kind of cement slurry can meet the cementing requirements in mid-deep formation （about 2000 m）, providing safe operation, good cement bond and lower formation damage than fresh water cement slurry. The successful application of new seawater cement slurry breaks the restriction of mixing slurry with fresh water for offshore cementing of intermediate and oil casings. In addition, a wide application of such new slurry will have very considerable social and economic profit.
