纵向多层储层电缆地层测试解释方法

Wireline Formation Testing Interpretation Method in Multi-Layer Formation Vertically

现有的电缆地层测试还没有考虑纵向多层情况下的解释模型和解释方法,实际储层都是具有纵向非均质性,常常表现为纵向多层的地质特征。由于泵抽式电缆地层测试器具有了泵抽排功能,能够进行大排量、长时间测试,在实际测试时,压力波动在纵向上很快传播到上下相邻储层,压力数据表现出多层储层特征。为了进行测试参数解释,本文提出了利用数值模拟器模拟纵向非均质储层电缆地层测试压力曲线,与电缆地层测试实测压力曲线拟合求解储层参数的方法,是纵向非均质储层单探头电缆地层测试储层参数解释的有效方法。

interpretation model and its interpretation method of the existing wireline formation tester didn t consider the situation of multi-layer in vertical direction,but the actual formation is heterogeneity in vertical direction,and often shows multi-layer geological features.on the other hand,the bumping wierline formation tester has function of pumping and pump drainage,it can test with high volume and long time,when testing,the pressure fluctuations quickly propagate the adjacent formation in vertical directi...
