【摘要】 低级序断层是影响剩余油聚集和注采关系的主要地质控制因素之一,油田开发后期对准确描述低级序断层的位置和走向提出了更高的精度要求。本文基于叠后地震资料,通过地震数据高频响应增强处理及蚂蚁体地震属性的提取,采取井点钻、测井、井间地震资料的联合解释方式,对工区断距2m以上的低级序断层进行了识别和描述,并得到开发动态数据的验证。由此认识到:充分利用并挖掘井-震联合勘探的潜力,能有效提高开发阶段小尺度地质体的描述精度,并为油藏描述提供更准确的地质模型。更多还原

【Abstract】 As low-grade faults have great influence on remaining oil distribution and injection-production relation,an accurate distribution of these minor faults is one of considerable interests in mature field development.After poststack seismic data are processed by high frequency enhancement and seismic attribute are obtained from ant tracking,we use a joint well-seismic interpretation to characterize low-grade faults with above 2-meter fault throw in the working area.This low-grade fault interpretation has been proven by well production information.Our study demonstrates that this joint well-seismic interpretation has great potential to improve the minor geologic body delineation for the mature field development stage.更多还原
