中文摘要:汶川地震断裂带科学钻探项目一号孔(WFSD-1)钻遇了30多米的断层泥。针对断层泥钻探的主要问题,对断层泥钻探泥浆体系进行了研究与应用,形成了具有高密度、低失水、低渗透、润滑减阻特点的泥浆体系,再加上重泥浆体系对地应力的平衡作用,成功地解决了断层泥的钻进取心问题,为顺利完成钻孔施工任务奠定了坚实的基础。

Research and Application of Drilling Fluid System for Fault Gouge Section of the Hole WFSD-1 of Wenchuan Earthquake Fault Scientific Drilling Project
Abstract:The first drilling hole of the Wenchuan earthquake fault science drilling project (WFSD-1) experienced up to more than 30 meters of the fault gouge drilling process. According to the research and application, the drilling mud system with high density, low water loss, low permeability, lubrication and resistance reducing was formed, and together with the equilibration by ground stress, coring in fault gouge was successfully made, which was the basis of the successful completion of the first hole construction in the Wenchuan earthquake fault scientific drilling.
