摘要

随着吐哈油田勘探开发的逐步深入,有一定规模、易于发现、能落实的和可供钻探的有利构造圈闭越来越少,这就需要加强对非构造的岩性圈闭、地下储层的分布及其特征进行研究。综合利用测井资料、地震层位信息以及地震资料进行储层反演是储层预测与研究的重要手段。在反演中,利用测井和层位作为约束,由于从井得到的初始波阻抗模型包含有低频成分,它对地震资料中所缺少的低频成分作了补偿,也对储层参数解的范围作了一定的约束;另一方面,由于测井资料纵向分辨率较高、地震资料横向分辨率较高,从而提高了反演效果的稳定性和地震资料垂向分辨率,也提高了这类反演方法在储层预测研究工作中的实际应用价值。
Along with the deepgoing of exploration and development in Tuha Oil Field, the "easy " oil and gas fields have been discovered.The favorable structural traps for drilling are less and less. This is necessary to study non-structural lithologic trap, reservoir distribution and its characteristics. It is an important way to predict reservoir by using the logging data, seismic data and seismic horizon information to have reservoir inversion. In the inversion , logging and horizon can be used as restraint, as the model of first break resistance contains low - frequency compositions, it compensated them lacked in seismic data and also restrained the range of reservoir parameter solution. In addition, according to high resolutions logging and seismic data in vertical and horizon, the stability of inversion result and resolution of seismic data in vertical have been improved and also enhanced the applied value of the inversion method in predicting reservoir study.
