摘要(Abstract)：

为了得到高品质的处理结果,对喇嘛甸油田的高密度地震资料采用了多次振幅补偿技术。应用球面扩散补偿、地表一致性振幅补偿和近地表吸收补偿方法,使地震资料的纵、横向振幅能量和频率得到较好恢复,补偿后的地震资料主频明显提高。分析认为,处理成果剖面上的地震信号能够最大幅度地反映沉积地层的变化,达到了地震资料相对保幅的目的,为解释微幅度构造和小断层识别奠定了基础。
In order to obtain high-quality processed results,multiple amplitude compensating technique is adopted for the high-density seismic data processing in Lamadian Oilfield.By means of the applications of spherical spreading compensation,surface consistence amplitude compensation and near-surface absorption compensation methods,much better recoveries are achieved for the vertical and horizontal amplitude energies and frequencies of the seismic data,the predominant frequencies of the data are obviously enhanced after the compensations.The analyses show that the seismic signals on the processed sections can maximally reflect the changes of the sedimentary strata and realize the purpose of relatively remaining the amplitudes of the seismic data,thus the high-quality seismic data are provided for the interpretation of the micro-amplitude structural characteristics and identification of the minor faults.
