中放废液处置场强自然造斜地层钻进的防斜纠斜

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

摘要:

核废液的永久性处置是一个世界性难题，其技术和安全可靠性要求极高，因此，对处置场的勘察和钻探技术质量要求极严。我国某压裂场是强自然造斜地层，其场地勘察和监测井的钻探施工孔斜是关键难题。在处置场的勘察和γ监测井的钻探施工中，通过采取相应的防斜纠斜工艺和技术方法，取得了良好的防斜纠斜措施，达到了勘察和监测井设计要求的各项质量指标，保证了勘察和钻探施工质量。

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.
