砂泥岩薄互层预测技术在东濮凹陷的应用

Prediction technology of sand shale and thin interbed in Dongpu depression

分析了在中原油田东濮凹陷开展的储层预测工作难以满足油气勘探开发需要的原因,论述了开展地震储层预测存在的主要问题:一是地质条件复杂,二是地震资料自身局限性,三是缺乏地震信息与地质信息有效沟通的桥梁,针对这些问题提出了相应的对策。指出砂泥岩薄互层地球物理研究应加强基础地质分析,强化基础测井数据分析,强化地震信息挖掘,加强地震、地质和测井的结合,加强地震资料处理解释结合力度。

The reasons why former reservoir prediction in Dongpu depression can not fulfill the requriments of oil and gas exploration in the region were analyzed. The main problems for seismic reservoir prediction were discussed too. The first one is complex geological condition and the second is the limitation of seismic data. The third one is lacking of connection between seismic information and geological information. Some measures for dealing with these problems were proposed. The basic geological analysis should be improved for geophysical study of sand shale and thin interbed. Besides that, logging data analysis, seismic information analysis, combination among seismic, geology and logging, combination between seismic data processing and interpretation should be improved.
