摘要
正交实验设计是一种研究多因素、多水平的、高效率、快速、经济的实验设计方法,广泛应用在工业设计、实验设计、影响因素敏感性分析等方面。本文通过分析澳大利亚煤层气A区块的前期勘探评价,在有利区域设计了一个先导试验井组,并在此基础上设计并研究了影响煤层气产能的5个因素:气量、裂缝原始渗透率、压裂有效缝长、压裂渗透率增大倍数、井距。研究表明,裂缝原始渗透率和含气量对产能的影响最大;同时预测了井组累产气量的概率分布,为该区域煤层气的开发部署提供参考。
The orthogonal experimental design is a high-efficient and economic method used to study multi-factor and multi-level experiment, which is applied widely in industrial design, experimental design and sensitivity analysis of influence factors, etc. The paper designs a pilot well group in the advantageous area based on preliminary exploration evaluation of block A in Australia, and studies the five factors affecting coalbed methane production, including gas content, original fracture permeability, effective fracture length, increased factor of fracture permeability and well space. According to research, the effect of gas content and original fracture permeability is the greatest on coalbed methane production. The proba- bility distribution of cumulative gas production is forecasted, which provide the reference for development of eoalhed methane in this area.
