利用不稳定试井资料求取饱和压力

Using Unsteady Well Testing Data to Get Saturation Pressure

应用压力恢复曲线对不同类型储集层的低地饱压差的未饱和油气藏求取饱和压力,不仅弥补了高压物性分析数量有限和取样条件苛刻等缺陷,而且拓宽了压力恢复曲线的应用范围,该方法在SX油田SN区块的应用,取得了令人满意的结果。

Using build-up pressure curves to get saturation pressure of unsaturated reservoirs with low formation-saturation pressure difference in different types of reservoirs can not only make up the defects of limited PVT data and rigorous condition for sampling,but also can expand the applied range of build-up pressure curves.The application of this method to SN block in SX oilfield has obtained satisfactory result.
