试井资料在某断层识别中的作用

Application of Test Data in the Identification of a Fault

某开发区井震结合研究应用成果表明断层更为破碎,新组合和核销的断层多为小断层。由于一些小断层突变不明显,可能会被认为干扰,所以结合测试资料可以准确识别小断层的存在;通过理论模型及计算公式可以计算出断层与测试井的距离;通过试井曲线并结合地质沉积相态图等静态数据,可以怀疑断层是否出现核销断层。试井资料在断层识别中的作用可为修正断层位置提供参考。

The results of a development zone combined with seismic application show that the fault is more broken, with the new combined and verified faults being small faults. As some small faults may be considered as interference without obvious mutation, the accurate identification of small fault layer should be combined with the test data. The distance between the fault and the test well can be calculated through theoretical model and the calculation formula. Whether there is a fault can be judged through well test curve and geological deposition phase diagram and other static data. The application of test data in fault identification can provide reference for correction of the fault location.
