克拉玛依油田相态分异试井曲线的分析与判别

ANALYSES AND IDENTIFICATIONS OF WELL TEST CURVES WITH PHASE SEGRAGATION IN KARAMAY OILFIELD

克拉玛依油田一部分复压试井曲线不同程度地反映出相态分异的现象，这不仅歪曲了试井曲线的形态，而且严重地掩盖了地层的真实特性，如果对这类资料处理不当就可能得出错误结论。为保证复压资料能正确评价油气藏，对相态分异效应进行了认真研究，以现场实际资料分析其形成机理，并找出相应的处理方法，使这一问题得到解决。

Some pressure buildup test curves in Karamay oilfield exhibit phase segragation phenomenon to various extent, which therefore distorted the shape of well test curves, and also covered the true properties of formation. If treated improperly, the erroneous conclusion is likely to occur. In order to enable pressure buildup data to correctly evaluate the reservoir, the phase segragation effect was analysed in details. Its forming mechanism was analysed by using actual data, and the corresponding solution obtained.
