【摘要】 胜利油田高精度地震勘探自1997年实施二次采集,已完成20多块高精度三维地震数据采集并投入资料解释应用,基础资料和解释应用对比效果显示,高精度地震资料比常规三维地震有大幅度提高。针对不同地区和不同勘探目标,开发应用了高精度地震精细标定技术、精细构造解释技术、高精度地震隐蔽岩性描述技术和高精度储层预测和流体识别技术。而高精度地震资料对岩性解释和复杂地质体的精细描述,在复杂断块、岩性、深层和潜山等隐蔽油气藏的勘探中发挥了重要的作用。更多还原

【Abstract】 A high-accuracy seismic exploration has been conducted in the second round of exploration for Shengli Oilfield since 1997 and a total of more than 20 surveys have been ac-quired and the data has been used in the interpretation. The comparison between processing and interpretation results shows that the quality of high-accuracy seismic data is much higher than the conventional seismic data. A high-accuracy seismic fine calibration,fine structural interpretation,high-accuracy subtle lithology description and high-accuracy reservoir prediction and fluid identification are applied in the oil-field development for the different areas and the different targets. The fine description technique has played a very important role in the exploration of lithology in-terpretation and complex geological body as well as subtle reservoirs like complex faulted block,lithology,deep formation and buried hill,etc.更多还原
