碎软煤层穿层压裂的层段优选方法研究

Layer Selection Method for Translayer Fracturing of Broken and Soft Coalbed

  • 摘要: 为解决现有层段优选方法在碎软煤层穿层压裂领域的适应性问题,提出了基于指标优先级评价的层段优选原则,据此原则建立了基于指标优先级评价的层段优选方法。该方法的基本步骤是,先使各影响因素分属于几类具有优先级评价关系的指标,再利用模糊综合评判方法对各类指标按优先级次序进行评价,最后确定出符合评价标准的综合甜点层段。与碎软煤层穿层压裂数值模拟结果的对比表明,该方法选出的层段较其他层段更容易产生预期的造缝效果,因此可用于指导碎软煤层穿层压裂的工程实践。
    Abstract: In order to solve the adaptability problem of existing layer selection methods in translayer fracturing of broken and soft coalbed, a layer selection principle based on index priority evaluation is proposed, and a layer selection method based on index priority evaluation is established. The basic steps of this method are as follows. Firstly, all factors are divided into several indexes with priority. Secondly, the fuzzy comprehensive evaluation method is used to evaluate all kinds of indexes with priority. Finally, the comprehensive dessert layer in accordance with the evaluation criteria is determined. Comparison with the numerical simulation results of translayer fracturing of broken and soft coalbed, the layer selected by this method is more likely to produce the desired fracture effect than other layers, so this method can be used to guide the engineering practice of translayer fracturing of broken and soft coalbed.
