foreword
This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents"
drafting:
This document replaces GB/T 33685-2017 "Technical Regulations for Land Seismic Exploration Data Processing", and is consistent with GB/T 33685-2017
In addition to structural adjustments and editorial changes, the main technical changes are as follows:
a) Changes related to processing design (see Chapter 6, Chapter 6 of the:2017 edition);
b) The technical requirements for direction correction and rotation of multi-wave (including shear wave and converted wave) seismic data are added (see 7:3);
c) The technical requirements for tide correction and water velocity correction have been added (see 7:4:3);
d) Added ghost reflection suppression processing of water area data, air gun source suppression bubble and zero phase processing, and water and land dual detection seismic data processing
Technical requirements such as double detection matching and wave field separation processing (see 7:5:2~7:5:4);
e) Added technical requirements for absorption attenuation compensation (see 7:8);
f) Added technical requirements for multiple wave attenuation (see 7:9);
g) Added technical requirements for residual static correction (see 7:12);
h) Add technical requirements for data interpolation and regularization (see 7:14);
i) Changed the relevant technical requirements for pre-stack time migration, pre-stack depth migration, and migration gather processing (see 7:17~7:19,:2017
Version 7:13, 7:14, 7:16);
j) Changed the technical requirements for post-stack data processing (see 7:20, 7:17, 7:18 of the:2017 edition);
k) Deleted the relevant technical requirements for the section display of the final result of seismic data processing (see 7:19 of the:2017 edition);
l) Changed the content related to the processing results (see Chapter 8, Chapter 9 of the:2017 edition);
m) Changed quality control and outcome evaluation (see Chapter 9, Chapter 8 and 10:2 of the:2017 edition):
