摘要
本实验目的在于克服现有技术的不足,提供一种用于固井过程中的防气窜前置凝胶体系,该体系具有以下特点:(1)与水泥浆具有良好的配伍性,与水泥浆任意比例混合不会污染水泥浆,具有较高的施工安全性;(2)该凝胶流变性良好、性能稳定,具有现场施工安全方便的特点;(3)该凝胶固化后具有很高的弹性,受力14k N时,压缩1cm后仍可恢复;(4)封隔性能良好,在承受13MPa压力时,未漏压。
The purpose of the experiment is to overcome the shortcomings of the prior art and to provide a gas barrier pre-gel system for the cementing process, which has the following characteristics： （1） Good compatibility with the cement slurry （2） The gel system rheological is good, the performance is stable,with the characteristics of safe and convenient on-site construction;（3） the gel after curing has a high elasticity, force 14kN, the compression can be restored after lcm; （4） Sealing perfomaance is good,when the pressure to withstand 13MPa,the instrument shows no pressure.
