摘要 

渤海Y构造浅层明化镇组储层发育,但已钻井证实该区储层含油气性有较大差异。高精度的地震流体检测结果对提高目标区明下段岩性圈闭钻探成功率意义重大。为研究目标区明下段储层含油气性,对目的层进行了一系列基于振幅类和频率类的叠后含油气性检测,但都无法对储层流体进行有效识别,可靠性较低。因此,转变研究思路,应用叠前流体检测技术,通过方法对比发现,在入射角小于30°时,直接通过叠前角道集提取出的流体因子对该区浅层油气较为敏感,与已钻井测井解释结果对应较好。应用该敏感参数进行储层含油气性预测取得了较好的效果。对类似地区叠前储层流体预测具有一定的借鉴意义。

Abstract

The Minghuazhen Formation of the Y structure in Bohai Bay Basin is well developed,but the drilled wells confirm that the oil-bearing characteristics of reservoirs have big differences in this area.The high reliability of reservoir fluid detection results are of great significance in improving the success rate of lithologic traps in the lower Minghuazhen Formation of the structure and activating the whole structure.In order to study the oil-gas bearing feature of the target area,the authors used a series of post-stack oil-gas detection methods based on amplitude and frequency,but still failed to identify the reservoir fluid effectively and reliably.By changing the research idea and using pre-stack hydrocarbon detection technology and method comparison,it is found that,when the incident angle is less than 30 degrees,the fluid factor directly extracted from pre-stack angle gathers is more sensitive to shallow oil and gas in this area,which corresponds well to the well logging interpretation results.The application of this sensitive parameter to the prediction of reservoir oil-gas bearing feature has achieved good results.It has certain reference significance for pre-stack reservoir fluid prediction in similar areas.
