MBM-GTQ盐水冲洗液体系的研究与应用

Study on MBM-GTQ Saltwater Drilling Fluid System and the Application

摘要:

盐水条件下配制出性能稳定且能维护孔壁稳定的冲洗液一直是困扰着新疆戈壁区域钻探施工的一个难题。通过冲洗液材料选型和在不同工区的试验研究，最终确定了MBM-GTQ盐水冲洗液体系配制与使用维护方案，并在新疆若羌县坡北铜镍矿强蚀变地层深孔施工和事故处理中取得了良好的应用效果。实践证明，MBM-GTQ盐水冲洗液体系是适合新疆若羌县坡北铜镍矿破碎蚀变地层的有效方案。

Abstract:

It has been a difficult problem to make up drilling fluid with stable performance under saltwater condition to keep borehole wall stability in the drilling construction in Gobi of Xinjiang. By the selection of drilling fluid materials and the test studies in different work areas, MBM-GTQ saltwater drilling fluid system was determined for use with good application effects for deep hole construction and accident treatment in intensily altered strata in Pobei Cu-Ni mine of Ruoqiang County. The practice proves that MBM-GTQ saltwater drilling fluid system is an effective scheme for the broken altered strata there.
