orey

测井约束地震储层反演是一种利用测井、地震、地质等多种资料进行地层波阻抗反演的技术。 Logging-constrained seismic reservoir inversion is a technology of layer acoustic impedance inversion using many kinds of information such as logging, seismic, geology and so on.
由于井筒污染、地层压实程度以及测井条件等因素的影响，用来进行层位标定和波阻抗反演的声波测井曲线难以反映岩性变化。
The acoustic velocity logging is used to horizon calibration and acoustic impedance inversion, but it is difficult to react the change of lithologic character, because of the affection of borehole damage, formation compaction grade and logging condition and so on.
通过多曲线重构技术将SP、GR、RT的特征信息融合到声波曲线中，丰富了声波曲线的地质信息，提高了储层预测的精度。
Through the technology of multi-curve reconfiguration, interfusing the information of spontaneous potential logging , natural gamma-ray log, resistivity logs to acoustic wave, enriching the geology information of acoustic wave and advancing accuracy degree of reservoir prediction.
