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。
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 acquired 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 oilfield development for the different areas and the different targets. The fine description technique has played a very important role in the exploration of lithology interpretation and complex geological body as well as subtle reservoirs like complex faulted block, lithology, deep formation and buried hill, etc.
