应用变速成图技术解释富台油田砂砾岩体构造

Interpretation of variable-speed imaging technique on the conglutinates structure in Futai Oilfied. Shengli

用常规速度量版进行地震时深转换,已无法满足高精度构造分析的需要。在分析胜利油区富台油田隐蔽油气藏地球物理特征的基础上,应用变速成图技术对各解释层进行变速时深转换,解决了由于砂砾岩体“速度陷阱”造成构造深度误差问题,提高了构造解释的精度,为勘探目标研究和申报储量奠定了基础。

The conventional time-to-depth conversion is not very useful in high-resolution structural analyses. Based on interpreting the geophysical characteristics of subtle hydrocarbon traps in Futai Oilfield, Shengli Province, variable-speed imaging technique is adopted to perform variable-speed time-depth conversions for different interpreted layer. The accuracy of structural interpretation is largely increased by eliminating depth errors resulting from ' velocity pitfalls ' of sand-conglomerate bodies through conventional conversioa This lays a foundation for exploration-targets recognition and reserves estimation.
