泡沫压裂设计中的敏感性分析

利用给出的泡沫压裂设计程序对影响泡沫压裂的主要参数进行了敏感性分析，着重讨论了泡沫压裂液的干度，气体密度，气体在裂缝中的膨胀体积，油层温度以及作为泡沫压裂液内相的砂子对泡沫压裂的影响。在泡沫压裂敏感性分析的基础上，得出了一些适用于泡沫压裂的规律，这些规律与适用于常规非泡沫压裂的规律是不同的。

Analysis for Sensitivity in the Foam Fracturing Design

By means of the design programme of foam fracturing, sensitivity is analysised to those major factors affecting foam fracturing. Because of the difference between foam fracturing fluid and regular non-foam fracturing fluid, the influence of such factors as quality of foam fracturing fluid, density of gas, expensive volume of gas in hydraulic fracture, formation temperature and the internal phase including sands on foam fracturing is particularly discussed.Based on the sensitivity analysis of foam fracturing, some results suitable for foam fracturing are derived, which are different from those applicable to regular non-foam fracturing.
