摘要

塔河油田奥陶系碳酸盐岩经风化剥蚀而形成众多低幅度的风蚀残丘、裂缝及溶蚀孔洞,储层的非均层性极强。通过在S48井区开展三维高精度地震采集,提高了地震资料的频率,拓宽了频带,提高了信噪比和分辨率。利用三维高精度地震采集数据,增强了对孔洞体地层楔状尖灭体、断层和河道的识别能力,对风化面残丘和水系刻画更精细,提升了目标区目的采收率。
The Ordovician carbonate rocks of Tahe Oilfield formed many low amplitude structures such as weathering residual mound,fracture and solution hole after weathering denudation,non-uniformity of the reservoirs was extremely strong.Through 3D high precision seismic acquisition in S48 well area, frequency of seismic data was improved,frequency band was widened,signal-to-noise ratio and resolution were improved also.Using the seismic acquisitioninformation,we may increase the identification capacity towards porous body,wedge-shaped strata pinch-out,fault and river channel,describe residual mound in weathering crust and water system in more detail,and enhance the oil recovery of the target zone.
