| 摘 要： | 研究区块地质构造较为复杂，显示的圈闭虽然较多，但落实的很少，主要是因为资料品质差，构造建模困难．从而导致速度分布规律认识不清。用测井约束地震反演技术对该区主要构造带作了速度反演，得到研究区块的地震剖面的速度反演剖面，在一定程度上反映了速度的变化规律，并与已有的钻测井资料相结合，综合得到研究区块的速度分布规律图，为研究区...

| Abstract: | Research on geological structure of the block is hard work. Though more traps were shown, yet they were rarely implemented, mainly because of poor data quality and difficulties in structure modeling, which can lead to an unclear understanding of the speed distribution. With the help of logging constrain, the velocity inversion was conducted by using the technology of seismic inversion. Logging constrained seismic inversion technique in Xiqiu area was used to observe the main belt velocity inversion. To a certain extent, it reflects the variation of speed, and with the present drill log data combined with the speed of integrated distribution, the reference model of time-depth conversion of the block and velocity prestack depth is then proposed. |
