| 摘 要： | 速度分析的精度和复杂构造的成像是地震资料处理中难以解决的问题,但两者又相互依赖,复杂构造的成像建立在精确的速度分析基础之上。根据地震资料处理技术的发展现状,解决上述两个问题的最佳方法是实施叠前精细速度反演和叠前时间(或深度)偏移处理1,2]。通过对大港油田关家堡地区地震资料进行叠前时间偏移处理,证明叠前时间偏移技术解决了关家堡地区构造、岩性变化复杂区域的偏移成像问题,降低了投资成本,为关家堡油田评价开发,提高钻井成功率,降低投资风险提供了可靠保证。

| Abstract: | The precision of velocity analysis and imaging of complex structures are the issues that are difficult to be solved in seismic data processing,but both of them rely on each other,i.e.imaging of complex structure is built on the fine velocity analysis basis.In view of the developing situation of seismic data processing techniques,the optimum methods the abovementioned two issues are solved are to perform fine prestack velocity inversion and prestack time (or depth) migration~ 1,2] .It is proved by prestack time migration processing of seismic data in Guanjiapu area of Dagang oilfield that prestack time migration solved the imaging problem in Guanjapu area characterized by complex structural and lithologic variation,reducing the cost and providing reliable guarantee for evaluation of development,improving drilling successful rate and reducing scheme risk investment of Guanjiapu oilfield. |
