适当修改电控箱体控制参数解决震源问题

Modify the parameters of decoder ap propriately to solve seismic vibrator problems

可控震源项目开工后,在通常情况下电控箱体控制参数会保持开工测试时确定的并经过认可的控制参数不变,直到项目结束。然而,部分项目施工周期长,施工面积较广,地形复杂多样。如果一直沿用同样的控制参数,有时难免会产生可控震源普遍存在质量指标严重超标但却查不出任何震源本身问题的情况。本文简单介绍中东地区某项目的两个典型案例,分析可控震源出现质量指标超标的原因,提出通过适当修改电控箱体控制参数来解决问题的方法,并验证和确认该方法的可行性。

After the start of a vibroseis prospecting project,all control parameters of the vibrator electronics usually remain unchanged until the end of the project.However,the prospecting period of some projects is long,the prospecting area is relatively wide,and the terrain is complex and diverse.If the same control parameters are used all the time,sometimes vibrator problem will inevitably occur.The quality-control data of vibroseis is generally out of standard,but engineer cannot find any problem the seismic vibrator itself.This paper briefly introduces two typical cases of a project in the Middle East region,analyzes the causes of the seismic vibrator quality-control data out of standard,puts forward a method to solve the problem by modifying the control parameters in the seismic vibrator electronics,also verifies and confirms the feasibility of this method.
