The particularity of high-radioactive waste fluid deposit determines the very strict requirements on the drilling construction for the location investigation of deposit site, especially in the exceptional large scaled tectonic crushed zone and complicated geological conditions. During the drilling operation of BS02 in Beishan of Gansu, many different technical measures were used, the large tectonic crushed zone and complicated formation were drilled through for Shiyuejing construction to meet the design requirements and ensure the engineering quality and hydrogeological test effect.
