井漏是川东地区钻井过程中最常见的问题.采用凝胶堵漏是一种新的技术应用.凝胶水化膨胀后具有较好的架桥作用和弹性变形能力,它能将水泥浆阻挡在井壁附近的漏失通道内直到凝固,以起到稳固的堵漏作用,提高堵漏效率.“,”Wel drain is the most common problem of the driling in East Sichuan.Gel plugging is a new technology applications.After the gel hydration expansion that has better bridging function and elastic deformability,it wil stop the grout in the wal near the leakage channel until solidified,which play a strong role in plugging and improve the plugging efficiency.
