摘要:
盐下油气田具有明显的无机生成特征,是深部找油气的一个新领域?勘探盐下油气田有三个关键,即:地质观念的改变,地球物理资料处理的进步与钻探技术的提高?现在已知90%的油气田与膏盐共存?盐层可作为盐下油气田的找矿标志?对盐层的精确成像,可大幅度地提高找寻盐下油气田的成功率?这同时也就为寻找我国急缺的钾盐矿床提供重要的资料?
关键词:  关键词:盐下油田  逆时偏移  油盐兼探

Abstract:
Abstract:The subsalt oilfield has distinctive features of a biogenetic origin and is a new field for exploring oil and gas. There are three key problems in the exploration of subsalt oilfields, i.e., new geological concept, applying reverse time migration in seismic data processing and special techniques in drilling. As 90% of oil fields coexist with salt, salt might be a prospecting indicator for the oil and gas field. Precise imaging of salt using reverse time migration can improve successful rate for exploration of subsalt oilfields, and at the same time it can get precious information concerning salt. The exploration of oil and salt at the same time seems to be an effective policy.
Key words:  sabsalt oilfield  reverse time migration  exploration of oil and salt at the same time
