水泥浆胶凝性质及对薄弱地层固井施工的影响

Influence of Cement Slurry Jellyfication on the Cementing Operation of Weak Formation

采用类似辽河油田浅井固井水泥浆进行胶凝性质的研究,讨论其静止一定时间后胶凝作用对重新循环时压力升高的影响。分析结果表明,由于胶凝强度的影响,在静止一定时间后重新开泵时压力升高可能导致压裂薄弱地层。

The influence of cement composition on the jellyfication of cement slurry is presented . The Jellyfication of cement slurry can be evaluated by Carri - Med CSL rheometer . It is shown that excessive jellyfication may result in the lost circulation of weak formation .
