RW水泥速凝早强剂在钻探护壁堵漏施工中的应用与研究

Application and Study on RW Cement Rapid Solidification Early Strength Agent in Wall Protection and Seepage Control for Drilling Construction

摘要:

针对复杂地层钻进水泥护壁待凝时间长、效果差的问题，通过大量室内试验，进行复合速凝早强剂的配制，作为水泥护壁堵漏外加剂，投入多个矿区不同矿种钻探施工中使用，实现候凝时间短、凝结时间可控、效果好，经济效益和社会效益明显。

Abstract:

Composite rapid solidification early strength agent was made by laboratory tests to improve the long cement curing time of wall protection for drilling in complex formation, which was applied in different mining types drilling as additive for cement wall protection and seepage control with short cement curing time, controllable setting duration and good quality.
