Analysis of a terminological base in the field of two-dimensional seismic surveying and proposals on its development and unification

Abstract

Introduction. The state of the terminological base used in the field of two-dimensional seismic surveying in the period 1933–2015 is analyzed and proposals to revise some key concepts are made.Aim. An analysis of the existing terminological base of the procedure of two-dimensional seismic surveying and the formation of a new base on the basis of a system approach.Materials and methods. An analysis of the terms used in educational, reference and normative literature on seismic surveying published in 1933–2015, followed by a critical analysis of the revealed terminological bases.Results. The investigated interval was divided into three stages on the basis of the state of terminology applied in seismic surveying. The first stage covered the period from 1933 to 1959, when the fundamental concepts of seismic surveying technology were passing the stage of formation. The quantity of terms at that time was small, many of them were characterised by unwieldiness or uncertainty of the described concept. In the period 1960–1992, the forming terminological base was presented in a state standard. The third stage was characterized by a slow pace of terminology development, when a number of publications showed a return to outdated or unsuccessful terms. The author identified the most stable terms, their unified names and definitions, and provided recommendations for their use. The following definitions of key concepts were proposed for revision: placement removal (distance), taking into account the variety of observation systems used in 2D seismic surveying; new terms inherited from the practice of 3D seismic surveying and group theory, including receiving line, placement removal, template, template step, order. A classification of templates was considered.Conclusion. The state of the terminological base in the field of two-dimensional seismic surveying, including its shortcomings and problems, was analyzed. It is proposed to improve the current terminological base by adding new terms and revising the existing definitions.
