中放废液处置场强自然造斜地层钻进的防斜纠斜

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。

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

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.
