地震反演在潜山油藏预测中的应用——以黄骅坳陷东部为例

APPLICATION OF SEISMIC INVERSION TO THE PREDICTION OF BURIED-HILL OIL RESERVOIRS-AN EXAMPLE FROM THE EAST HUANGHUA DEPRESSION

摘要: 潜山的石油成藏过程较为复杂,使得油层的分布常常难以确定。作者在对黄骅坳陷东部潜山的研究过程中,提出一种新的油层检测方法:首先,利用油层在测井上的响应特征合成油层特征曲线;然后,进行有井约束的综合地震储层特征反演,得到油层的地震反演体;最后,经地质分析,直接在所得到的反演体上识别出油层,圈定油藏的展布范围,为油田的开发提供地质依据。

Abstract: The formation of oil reservoirs in buried hills is very complex.This makes it difficult to confirm oil-play distribution.While studying buried hills in the East Huanghua Depression,the authors suggested a new way to find out oil plays.First,the logging response characteristics of an oil play were used to synthesize the characteristic curves.Then,the comprehensive seismic reservoir characteristic inversion restrained by wells was done to obtain the seismic inversion body of the oil play.At last,by geological ana-lysis,the oil play was recognized directly from the inversion body,and the distribution range of oil pools was determined.This will provide geological bases for the development of oilfields.
