| 摘 要： | 预测煤层气井的压裂难易程度是制定煤层气井压裂方案的关键问题。目前,国内外还没有形成完善的压裂预测方法。以韩城区块煤层气井的压裂为例,通过测井资料和现场压裂数据,利用SPSS统计分析软件,运用多元逐步回归分析方法进行拟合,得到了煤层气井压裂难易程度预测公式。经过检验,发现该公式预测效果较好,具有一定的参考价值。

| Abstract: | To predict the difficulty of coalbed methane(CBM) well fracturing is the most important issue in CBM well fracturing program.There is no perfect system for predicting CBM well fracturing at home and abroad.In this paper,we discuss the hydraulic fracturing of coalbed methane well in Hancheng block.Some regular patterns are concluded through the analysis of well logging data.We fit the data by SPSS software and get the estimation formula about the difficulty of hydraulic fracturing.This paper has some reference value. |
