埕岛油田东部斜坡带下第三系油藏以三角洲、浊积扇隐蔽岩性油气藏为主 ,是近年在该区发现的又一含油层系。该带储层埋藏深、厚度变化大 ,油气聚集成藏复杂。本文对利用测井约束反演技术进行储层预测方法进行了探讨 ,通过合成地震记录标定、子波提取和薄层识别等技术 ,结合本区特点 ,对储层进行追踪、预测 ,查清了该地区储层的分布规律 ,落实了有利的岩性圈闭 ,获得了较好的效果。
The Tertiary reservoirs along the east slope of Chengdao Oilfield are mainly concealed lithologic reservoirs of deltaic and turbidite fans and are another oil-bearing reservoir discovered in this area in recent years. The belt buried deep, large thickness changes, hydrocarbon accumulation and accumulation of complex. In this paper, the reservoir prediction method using logging constrained inversion technique is discussed. Through synthetic seismogram calibration, wavelet extraction and thin-layer identification, combined with the characteristics of this area, the reservoir is tracked and predicted. The distribution of reservoirs in the area, the implementation of favorable lithological traps, and achieved good results.
