GB/T 33583-2025Technical specification for data acquisition of petroleum seismic exploration (English PDF)

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part

1.Structure and Drafting Rules of Standardization Documents". Drafting. This document supersedes GB/T 33583-2017 "Technical Specification for Data Acquisition in Onshore Petroleum Seismic Exploration" and is consistent with GB/T 33583-2017. Compared to previous versions, aside from structural adjustments and editorial changes, the main technical changes are as follows:

a) Added terms and definitions such as near-surface quality factor, wired seismic acquisition, and nodal seismic acquisition (see 3.1~3.27);

b) Terms and definitions such as plains, mountains, loess plateaus, deserts, water-land transition zones, urban areas, and obstacle zones have been removed (see section 3.1~ of the.2017 version). 3.7);

c) Added "Demonstration and Technical Requirements for Seismic Acquisition Projects" and "Experimental Work" (see Chapters 4 and 6);

d) Modified the design principles of 2D seismic survey lines and 3D seismic network (see 4.4.1, 4.4.2, and

4.2.1 in the.2017 version). 4.2.2.1, 4.2.3, 4.3.1~4.3.3);

e) Added content related to the design principles of work area reconnaissance and data collection parameters (see 5.2, 5.3.1);

f) The relevant content regarding high-fidelity in the sections on high-fidelity construction and its definition, receiving factors, and instrument factors has been deleted (see the.2017 edition). 4.5.4.3, 4.5.5.4, 4.5.6.4);

g) Added content related to forward simulation and data-driven analysis (see 5.3.4);

h) The content regarding air gun firing and instrument factors has been modified (see 5.3.6.4, 5.3.8, and

4.5.6 in the.2017 version);

i) Added content related to electric spark excitation (see 5.3.6.5);

j) Requirements for surveying desert areas, loess source areas, and near-surface quality factors have been added (see 5.4.3);

1 Scope

GB/T 33583-2025 is the Chinese national standard covering shooting a seismic survey - the geometry of sources and receivers and the fold it produces, the source parameters, the recording and the quality control in the field, the noise tests, and the observation report that goes with the tapes. At 26,500 words. Issued on 5 October 2025, it has been in force since 1 May 2026, replacing GB/T 33583-2017.

This document specifies the design, field construction, and quality inspection procedures for 2D and 3D petroleum seismic data acquisition in onshore, land-sea transition zones, and offshore areas. Technical requirements for processes such as evaluation, data delivery and acceptance. This document applies to the entire process of acquiring 2D and 3D seismic data for petroleum exploration in onshore, water-land transition zones, and offshore areas. Other engineering exploration projects can refer to this document. implement.
