| 中文摘要:地层压力变化是导致孔内情况复杂化的关键因素，地层压力预测是钻探施工中泥浆设计和事故防范的重要手段，合理预知地层压力情况有助于最大限度地解决深孔钻探中的复杂问题[1]。近年来，地层应力预测技术在国内外得到了广泛探讨，而传统的水压致裂地层压力测量方法仍然是简单实用的手段之一。通过云南某矿区复杂地层深孔钻探工程中的应用实例，验证了地层压力预测在绳索取心钻探工程上的合理性和可行性。 |

| Abstract:The change of underground formation pressure is crucially related to the complexity of borehole condition. Formation pressure prediction is an important means for borehole design and drilling risk control, and rational prediction of formation pressure is furthest solving complicated difficulties in deep drilling. In recent years, modern techniques of earth stress prediction have been widely explored in academic circle and application field in the world; but the traditional water-pressure test is still the most applicable method due to its simplicity of on-site operation. In this paper, by the case of a deep drilling project in complex formations in Yunnan Province, the rationality and feasibility of formation pressure prediction in wire-line coring drilling activities are verified. |
