摘要

摘要: 为了更好地揭示崖13-1气田的泥岩夹层及剩余气分布,提高采收率,尝试了基于纵波地震和四分量地震的弹性波阻抗反演。利用常规纵波地震资料对崖13-1气田气层进行了多角度同时反演;利用四分量地震资料进行了纵波和转换横波波阻抗反演。基于常规纵波地震资料的弹性波阻抗反演剖面的分辨率较高,气层纵波波阻抗与盖层的纵波波阻抗差异大于横波,但横波波阻抗分辨率比纵波波阻抗高,对气层细节反映得更清楚。利用弹性波阻抗反演结果可以较好地发现剩余气、泥岩夹层及气水界面。转换横波地震资料的分辨率较低,基于四分量地震资料的弹性波阻抗反演的分辨率也比较低。

Abstract: Doing seismic inversion was a general task during petroleum and natural gas prospecting and developing.Inversion was a key technique for reservoir forecasting. We could forecast the transverse distribution of reservoirs, if the impedance of P-wave was in good correlation with the lithology. But, if the correlation was complicated, elasticity impedance inversion was needed to forcast reservoir and its petroleum and natural gas. The elasticity impedance inversion result from Ya13-1 gas field shows that the resolution of elasticity impedance inversion profiles was higher based on P-wave seismic data.The P-wave impedance difference was greater than S-wave impedance between the gas reservoir and the caprock of the reservoir. The elasticity impedance inversion data were used to find residual gas, mud interlayer and gas-water interface. It helps us heighten the recovery ratio. Because the resolution of conversion-wave seismic profile was lower, its resolution of the elasticity impedance inversion profile was also lower based on four components seismic data.
