硅酸盐聚乙稀醇冲洗液在新疆砂岩性铀矿钻探中的应用

Application of Silicate Polyvinyl Alcohol Washing Fluid in Sandstone Uranium Deposit Drilling in Xinjiang

摘要:

分析并研究了硅酸盐聚合物冲洗液体系的作用机理，配制了一套专门针对砂岩性铀矿岩心钻探中复杂地层孔段长、极易引发多种孔内事故的冲洗液体系。生产实践证明，该冲洗液体系完全能够满足绳索取心钻进工艺各项性能要求，并在对付砂岩性复杂地层方面具有良好的效果。

Abstract:

Analysis was made on the mechanism of silicate polymer washing fluid system, a set of washing fluids especially for long borehole section with hidden downhole accidents in core drilling of sandstone uranium deposit. The practice shows that this washing fluid system can satisfy all requirements of wire-line coring drilling technologies and has good effects in dealing with complex sandstone formations.
