摘要

吉林松南是东北油气资源勘探重要地区之一,获取高度精确的地震资料是该区油气勘探首要任务。地震勘探前要做干扰波调查。干扰调查包括规则干扰调查、高频噪声调查及调查结果分析等工作。调查所用的测线一般采用道距为3m～5m的小排列,连续接收几个排列,并且不使用混波和滤波,以便清楚地连续追踪各种规则干扰波。做扰波调查是为了确定干扰波类别和特征,并通过专业软件进行压制模拟,配合野外的试验确定干扰波压制所采用的检波器类型、组合方式和组内距,以便掌握高精度的地震资料。
Songnan area of Jilin province is one of major areas in northeast China for exploring oil and gas resources.The acquisition of seismic data with high accuracy is a primary task in oil-gas exploration in the area.It is necessary to make an investigation on interference waves prior to seismic exploration,which consists of the investigation on regular interference and high-frequency noise and the analysis of the findings.The used survey line is generally arranged by minispread with the trace interval 3-5meters,continuing to receive several spreads without using mixing and filtering in order to continue to clearly track all kinds of regular interference waves.Doing so is to determine their kinds and features,imitate them in a suppression manner with the help of the special software and confirm the type of seismometer used in suppression,its assemble pattern and element interval by combining field test in an effort to acquire seismic data with high accuracy.
