磁化钻井液在川东地区深探井——苟西２井的现场应用试验表明，钻井液经磁化处理后，性能得到明显改善，井壁稳定性增强，井径扩大率减小，钻井液维护处理周期延长，具有明显的技术经济效果 The field application tests of magnetized drilling fluid in deep exploration well-Gengxi 2 well in eastern Sichuan show that the performance of drilling fluid is obviously improved after magnetization treatment, the stability of borehole wall is enhanced, the diameter expansion of borehole is reduced, and drilling fluid maintenance treatment Extend the cycle, with obvious technical and economic results
