摘要
介绍了牡丹江金厂矿区金刚石岩心钻探中钻井液的使用和堵漏技术应用问题。所采用的钻井液体系具有良好的防塌效果,且适应性强、粘度适中,形成的泥饼薄而致密且有韧性,能够有效地解决金刚石岩心钻探中出现的钻井液悬浮能力差、漏失严重的问题,对充分发挥金刚石钻进特点,防止孔壁垮塌起到了良好的作用。以ZK-0003孔为例,说明所采用的堵漏技术效果明显、成本低,堵漏后钻孔孔壁稳定,可在实际生产中推广应用。
This paper introduces the drilling fluids and lost circulation control technology applied in Jinchang gold mine, and takes an example of diamond wire-line coring drilling well （ ZK - 0003 ） to illustrate the high efficiency, low cost and stable hole wall. The drilling fluid system had good effect of caving prevention and lost control with strong adaptability and suitable viscosity; the formed thin mud-cake was dense and tough, with which low carrying capability and serious water loss were solved in small diameter wire-line coring drilling.
