摘要
刘家窑井田勘探施工中,井田砂砾岩地层深厚、地层复杂、断层发育、煌斑岩侵入等地质因素的存在,导致钻探难度巨大,为此采用优质高效的低固相泥浆和套管护壁工艺来防止孔内坍塌、掉块,提高钻进效率,降低钻探成本,成效显著,为在该井田及其周边区域进行勘探施工提供了可靠依据。
In the exploration construction process of Liujiaoyao Coalfield, due to the existing geolog- ical factors of deep glutenite strata, complex strata, fault development and intrusion of lamprophyre, which increased the difficulty of drilling construction in the orefield. In order to solve the problems, by repeated practice and constant study, the high-quality and efficient low solid mud and casing pipe wall protection technique are adopted to improve the drilling efficiency, reduce drilling cost, the practice effects is signifi- cant,which provide some reliable reference for the drilling construction work in the orefield and its sur- rounding area.
