基于地震波形及属性优选的优势储层预测——以渤海湾盆地A油田为例
|
摘要
渤海湾盆地古近系中深层(埋深大于2500m的古近系)油藏,储层埋藏深、沉积类型多样,储层预测问题已严重制约该地区中深层开发井的实施成效。以渤海湾盆地A油田为靶区,提出了一套适合该区古近系中深层储层预测的技术思路与方法,精细刻画了中深层沙河街组三段的储层展布特征,并成功用于指导油田开发井实施。在高分辨率层序地层框架下,建立了油田靶区井震响应关系模板,依据多角度地震属性切片总结不同目标砂体时空配置关系;在目标砂体内部,开展了基于地震模型正演的储层精细描述,以垂向波形与岩性组合的耦合关系,建立了地震反射波形剖面与砂体内部波形平面分布特征关系,识别目标砂体的优势储层发育结构。在A油田的随钻过程中,应用该技术有效规避了储层风险,16口开发井实施效果均较好。
In Bohai Bay Basin,the Paleogene mid-deep reservoir(the buried depth being more than2500 m)was deeply buried with various types of sedimentary systems,while the problem of reservoir prediction seriously constrained the implementation effect of mid-deep development wells.By using A Oilfield in Bohai Bay Basin as a target area,a set of technical ideas and methods suitable forthe prediction of mid-deep Paleogene reservoirs in this area were put forward.The distribution characteristics of mid-deep reservoir in Paleogene were accurately described,which was successfully used for guiding the oilfield development.For the control of high resolution sequence framework,the templet of logging-seismic response relationship in the target area was established.According to the multi-angle seismic attribute section,the space-time configuration relationship of different target sand bodies was summarized.In the target sand body,fine reservoir description based on seismic model forward modeling was carried out.Based on the coupling relationship between vertical waveform and lithologic combination,the relationship between seismic reflection waveform profile and the plane distribution characteristics of waveform inside the sand body was established,and the advanced reservoir development structure of the target sand body was identified.In the process of logging while drilling in A Oilfield,the application of this technique effectively avoids the reservoir risk,and good effects are obtained in the application of 16 development wells.
