地震振幅的多井质控技术及应用
Multi-well quality control technology and application of seismic amplitude
摘要
Abstract
The current well control amplitude processing technology uses single well data to control the amplitude recovery effect of sidetrack,but it can't deal with the parameter difference between multiple wells and control the data recovery effect far away from sound points.This paper uses the correlation coefficient as the standard to optimize the quality control wells.The amplitude energy trend of well synthetic seismic records is used as the scale to control the compensation effect of n parameter in the exponential function compensation method to ensure the correctness of the vertical energy trend of seismic data.The S-shape well model is constructed based on the logging data of two quality control wells and interpretation horizon.Based on the S-shape well model profile as the standard,the compensation effect of n parameter and regional amplitude compensation factor are controlled to ensure the correctness of the amplitude trend of seismic data far away from well points.The results show that the quality control method proposed in this paper for amplitude preserving processing of seismic data is effective and provides a basis for judging the correctness of the relative relationship between vertical and horizontal amplitude of seismic data.关键词
