摘　　要：为了提高浅井低温油层(即延安组油层)固井质量,通过对水泥添加剂和水泥浆体系反复筛选与评价,固井方案的研究与论证,在原来使用的水泥浆体系的基础上,研究出了适合于靖安油田、安塞油田浅油层的水泥浆体系和固井工艺技术,通过现场应用,固井质量达到优质,为靖安油田、安塞油田浅油层进一步开发提供了有力的技术支持。In order to improve the cement job quality at the cryogenic oil reservoir of shallow wells,cement additive and cement slurry system is selected and evaluated repeatedly while cementing scheme is studied and proved.Then based on the cement slurry system used in the past,the cement slurry system and cementing technology have been worked out,which are suitable for shallow oil reservoir of Jingan oilfield and Ansai oilfiled.By the practical use of them at worksites,cement job quality become excellent.And this provides strong technical support for the further development of shallow oil reservoirs at Jingan and Ansai oilfields.
