| 摘 要： | 利用5次地层倾角测井资料，采用交会图和井径矢量分析技术，建立井径、井径差值、井眼横截面积、井径积分(井眼纵切面积)、井眼容积等多项参数的测井评价方法。4种交会图法显示在一定井下地质条件下，即一定的温度、应力作用下，盐岩呈现出明显的初期蠕变和二期蠕变过程，其中初期蠕变的完成大约在30 d之后，此过程的蠕变曲线斜率较大，表明蠕变速率变化较大，且蠕变速率呈衰减趋势；30 d后蠕变曲线斜率明显变小，表明蠕变速率变化较小，进入稳定的二期蠕变阶段。上述结果表明，利用测井资料可以很好地评价盐岩的蠕变特性，为金坛储气库运营的稳定性分析提供有效的参考依据。

| Abstract: | Based on five logging data,the crossplot and caliper vector techniques are introduced to build the logging evaluation method with multi-parameter,for example,caliper,caliper difference,borehole cross-sectional area,caliper integral(borehole vertical-sectional area),borehole volume.Four crossplot methods clearly show the first stage and the second stage of creep under certain underground geological conditions.The first stage of creep is after 30 days.In this period the slope of creep curve and creep velocity... |
