    摘要
  • 摘要: 钻进轨迹调控是实现安全高效复合定向钻进的关键技术之一。因孔内钻具受力状况和分析模型构成不同，现有的地面石油与天然气钻探领域复合定向钻进轨迹调控理论不能直接应用于煤矿井下。在分析煤矿井下双动力复合定向钻进技术特性的基础上，对螺杆马达结构弯角和回转离心力进行了等效处理，依据准动力学原理建立了双动力复合定向钻进轨迹调控模型，分析了螺杆马达结构弯角、钻压和钻孔孔径扩大率对钻进轨迹调控的影响规律。结果表明：增大螺杆马达结构弯角有利于提高滑动造斜的造斜率，不利于回转稳斜钻进轨迹调控；增大钻压不利于提高滑动造斜的造斜率，有助于回转稳斜钻进轨迹调控；增大钻孔孔径扩大率不利于提高滑动造斜的造斜率，对回转稳斜钻进轨迹调控影响较小。基于钻进轨迹调控影响规律分析，提出了双动力复合定向钻进轨迹调控方法，给出了不同参数设置建议：螺杆马达结构弯角一般为1.25°，钻具级配较大时可设定为1.5°；考虑钻具安全性情况下可适当提高钻压，在坚固性系数较低的煤系地层中钻进时钻压设定不宜过大；回转速度一般为40～60 r/min；钻孔孔径扩大率一般为4%～6%；回转稳斜孔段比例≥80%。在保德煤矿大盘区瓦斯抽采3 000 m以上超深定向长钻孔试验中应用双动力复合定向钻进轨迹调控方法，结果表明钻进效率高，钻进轨迹调控能力强，满足深孔高效钻进要求。

     

    Abstract: Drilling trajectory control is one of the key technologies to achieve safe and efficient composite directional drilling. Due to the different force conditions of drilling tools in the hole and the composition of the analysis model, the existing trajectory control theory of composite directional drilling in the field of surface oil and gas drilling cannot be directly applied to the coal mine. Based on the analysis of the technical characteristics of dual-power composite directional drilling in coal mines, structural bend angle of screw motor and rotary centrifugal force are treated equivalently. The dual-power composite directional drilling trajectory control model is established based on the quasi-dynamic principle to analyze the influence law of structural bend angle of screw motor, weight on bite and borehole diameter expansion rate on the trajectory control. The results show that increasing structural bend angle of screw motor is conducive to increasing the build-up rate of the sliding deflection, and is not conducive to the control of rotary angle holding trajectory. Increasing the weight on bit is not conducive to improving the build-up rate of the sliding deflection, and is conducive to the control of rotary angle holding trajectory. Increasing the expansion rate of borehole diameter is not conducive to improving the build-up rate of the sliding deflection, and has little effect on the control of rotary angle holding trajectory. Based on the analysis of the influence law of drilling trajectory control, a dual-power composite directional drilling trajectory control method is proposed, and different parameter setting suggestions are given. The structural bend angle of screw motor is generally 1.25°, and can be set to 1.5° when the drilling tool grade is large. In the context of the safety of the drilling tool, the weight on bit can be increased appropriately, and the weight on bit setting should not be too large when drilling in coal-measure strata with low consistent coefficient. The rotary speed is generally 40-60 r/min, the borehole diameter expansion rate is generally 4%-6%, and the proportion of rotary angle holding section is no less than 80%. The dual-power composite directional drilling trajectory control method is used in the test of super-deep directional long drilling for gas extraction above 3 000 m in the large area of Baode Coal Mine. The results show that the drilling efficiency is high, the drilling trajectory control capability is strong, which meet the requirements of efficient drilling in deep holes.
