摘要
研制成功的磺化沥青复合剂(SHA),具有防塌,降失水及稀释作用等性能,是一种多功能孔壁稳定剂.通过在4个矿区10多个钻孔中应用,证明其防塌性能好,使钻进效率提高,孔内事故及材料消耗减少.SHA为粉剂,易溶于水,便于运输、储存及使用.
ABSTRACT SHA is a multi-function well wall stabilizer with properties of anti-caving, reduction water loss and thinning of mud cake. Use of SHA in over ten boreholes in four fields indicated that SHA can improve rate of penetration, decrease hole accident and reduce material consumption. As a powder product, it dissolves easily in water, thus being easy for transportation, storage, and usage.
