通常会对地震数据进行阻抗反演，以定量预测储集层的性质。岩石性质和阻抗之间的校准被用来进行远离井控的预测。这些预测的质量取决于许多因素，包括岩石性质的阻抗变化量、地震数据的质量和阻抗体积的可靠性。岩性阻抗的变化是由地质决定的，并且是设定的。地震数据的质量总是可以改进的，但在某些时候，我们需要处理处于当前状态的数据。
Seismic data are routinely inverted for impedances to quantitatively predict reservoir properties. Calibrations between rock properties and impedances are used to make predictions away from well control. The quality of these predictions depends on many factors, including the amount of impedance variations in rock properties, quality of the seismic data, and reliability of the impedance volume. The rock property impedance variations are dictated by geology and are set. The seismic data quality can always be improved, but at some point we are left to work with the data in their current states.
