摘要
以文献的资料为例,用量板法分析水压致裂数据,并与原方法比较,结果表明,在深度较大的情况下,新方法所得出的最大水平主应力较原方法所给出的结果系统偏大,把这个趋势与实验室结果相比,量权法所给出的应力结果可能更接近野外实际应力值。文中还讨论了确定封闭压力的方法。
In this paper,we put forward a new method-measuring scale to deal with the hydrofracturing stress data,we compared the values of maximum horizontal main stress obtained from these two methods. The results showed that the value of the new method is systematically larger than that of the old method. Compared this tendency with the laboratory results, we found that the stress value obtained from the new method is much closer to the practical value of the field observation.
