复杂区高效采集施工模拟方法与应用

Operation simulation method and application of HPVA in complex terrain

地震资料采集以"两宽一高"技术、高效采集技术的应用为主要发展趋势。主要特点是人员设备投入大、项目运行成本高,效率估算及项目的施工模拟对投标报价及后续的项目生产组织有着非常重要的意义。针对复杂区高效采集模拟效率估计需要考虑两个方面的问题:一是不同的可控震源施工模式混合运用;二是不同的工区地形、障碍物的存在。本文提出一种统一考虑不同施工模式和地形障碍物影响的高效采集模拟方法,解决复杂地表的施工模拟问题。模拟结果表明:复杂区高效采集可控震源施工模拟方法能够估算项目生产效率,对生产组织方式、影响生产要素能够进行量化分析,对高效采集可控震源施工具有很强的指导意义。

The strategy of high density,broadband and wide azimuth 3 D has become the dominant land seismic technology tendency in the industry.The main characteristics are large investment in personnel and equipment,high project operation cost,efficiency estimation and project operation simulation are of great significance for bidding quotation and subsequent project production organization.In view of the complex terrain,the efficient acquisition simulation efficiency estimation needs to consider two aspects:1.The mixed use of different vibrator operation modes;2.The existence of different terrain and obstacles in the work area.In this paper,an efficient acquisition and simulation method is proposed to solve the operation simulation problem of complex surface.The simulation results show that the simulation method of HPVA can estimate the production efficiency of the project,make quantitative analysis on the operation mode and the factors affecting production,and has a g ood guidance for the operation of HPVA project.
