塔河油田碳酸盐岩为古岩溶喀斯特化与受后期构造叠置改造的孔、洞、缝等组成的非均质储层,储层具有规模不同、空间形态不规则、充填性质各异的复杂组合特征以此为对象通过分解地震波场不同特征信号,开发了一系列针对不同储层目标的叠前叠后地震预测技术,不同特征地震预测结果经综合叠置验证分析,实现了残丘体上叠置的孔、洞、缝及古地貌的精细刻画及表征,展示了缝洞空间纵横交错的叠置关系,提高了复杂储层空间展布规律的认识及精确定位。
The carbonate rocks in the Tahe oilfield are heterogeneous reservoirs composed of karstification of karstification and pores, holes and seams superimposed by later structural alteration. The reservoirs have different scales, different spatial forms and different filling properties Based on this, a series of prestack and post-stack seismic prediction techniques for different reservoir targets are developed by decomposing different characteristic signals of seismic wavefields. The results of different characteristics of seismic prediction are verified by comprehensive overlay verification, The fine characterization and characterization of the overlying holes, holes, seams and palaeogeomorphology shows that the space of cracks and caves intersect alternately in a crisscross pattern and enhances the understanding and precise positioning of the spatial distribution of complex reservoirs.
