Deviation Prevention and Correction for Intermediate Level Waste Liquid Disposal Field in Strong Natural Whipstocking Stratum Drilling

Abstract:

Because of very high requirements on the technique and safety, the permanent disposal of nuclear waste liquid is a worldwide difficulty, and investigation on disposal field and drilling technology is strictly demanded. The paper introduced a fracturing field in China, which is in strong natural whipstocking stratum; the field investigation and hole deviation in monitoring well drilling are important difficulties. Relative technologies of deviation prevention and correction were adopted for drilling construction in investigation of 2 disposal fields and γ monitoring well with good effect.
