摘　　要：针对低温条件下 ,水泥浆因候凝时间长 ,极易造成油、气、水侵 ,导致固井后水泥环不致密 ,固井质量差这一现象 ,研制了一种新型低温复合早强促凝剂CN - 2 ,并完善了与之配套的水泥浆体系 ,从而满足各类低温条件下的固井施工 ,为低温浅层油气井固井质量的提高提供了可靠的保证。As the cement slurry setting time is relatively longer in low temperature,oil,gas and water migration is easily happened,which results in bad annular cement bonding and bad cementing quality.In order to cope with this situation,a new kind of low temperature compound early strength promoter and related compatible cement slurry system is developed.It can meet different kinds of cementing operations and assure the cementing quality improvement for low temperature oil and gas well.
