Рассмотрены вопросы литолого-стратиграфического расчленения и литолого-фациальной характеристики разреза, тектонического строения и палеотектонического анализа, нефтегазоносности и сейсмогеологической характеристике района исследований.
Now that this book has been in use, through various editions, for more than 22 years, I must reflect on the many contributions that have ensured its success. Most particularly I must thank Bill Abriel, Rebecca Latimer, David Roberts, Greg Partyka, Malcolm Lansley, Les Denham, and Dave Agarwal for writing sections for me. Many people, too numerous to name, have kindly released data examples and discussed their interpretations with me. AAPG and SEG have cooperated in the book’s publication since the Fifth Edition. Anne Thomas has edited all editions. The high quality of the product depends significantly on her editorial expertise.
Since the first edition of 3D Seismic Survey Design appeared in 2002, seismic data acquisition has seen many changes, most of which have been captured in this second edition. This book by Gijs Vermeer describes in detail the properties of 3D acquisition geometries and shows how these properties naturally lead to the 3D symmetric sampling approach to 3D survey design. Many examples from the literature are used to illustrate good and less good choices of acquisition parameters. The link between survey parameters and noise suppression as well as imaging is an intrinsic part of the contents. This book should be of great interest to the designer of 3D seismic surveys, but also to every geophysicist who uses 3D seismic data to retrieve accurate information on the properties of the subsurface. <...>
Three-dimensional (3D) seismic data have had a substantial impact on the successful exploration and production of hydrocarbons. Although most commonly acquired by the oil and gas exploration industry, these data are starting to be used as a research tool in other Earth sciences disciplines. However despite some innovative new directions of academic investigation, most of the examples of how 3D seismic data have increased our understanding of the structure and stratigraphy of sedimentary basins come from the industry that acquired these data.
The oil and gas business has witnessed over the past decade a quantum leap in effectiveness of geophysics in E&P operations. Indeed the industry may never before have witnessed a technological advance as profound as or with the overwhelming business impact of 3-D seismic. Under refinement and development for almost three decades, the 1990s saw the coalescing of technical cross currents that have shaken the economic foundations of the oil and gas industry, and have fueled a world economic growth spurt. Today oil prices have been reported as being at the lowest level in 50 years, due in a major part to inordinately high supplies; that is, higher volumes found by 3-D seismic. <...>
In the past decade, 3D reflection seismology has replaced 2D seismology almost entirely in the seismic industry. Recording 3D surveys has become the norm instead of the exception. The application of 2D seismology is limited mostly to reconnaissance surveys or to locations where recording 3D data is still prohibitively expensive, such as in rough mountains and wild forests. However, academic research and teaching have struggled to keep up with the 3D revolution. As a consequence of this tardiness, no books are available that introduce the theory of seismic imaging from the 3D perspective. This book is aimed at filling the gap.
This quotation is familiar to all geoscientists, but it is just as pertinent today as it has ever been. Today’s advanced geophysical workstations are truly magnificent tools, but we should remember that they are only tools. The skill remains the geological interpretation of geophysical data. I sometimes apologize to myself and others that this still needs to be said — but it surely does! I am indeed disappointed by the general standard of seismic interpretation in the world today.
В настоящее время в Западной Сибири существует проблема истощения крупных месторождений углеводородного сырья с относительно простым геоло-гическим строением. В сложившейся ситуации дальнейшее восполнение ресурс-ной базы возможно за счёт поиска сложнопостроенных ловушек углеводородов (УВ). Одним из таких объектов является исследуемый участок, расположенный в юго-восточной части Каймысовского свода.
3-D seismic data have become the key tool used in the oil and gas industry to understand the subsurface. In addition to providing excellent structural images, the dense sampling of a 3-D survey can sometimes make it possible to map reservoir quality and the distribution of oil and gas. The aim of this book is to help geophysicists and geologists new to the technique to interpret 3-D data while avoiding common pitfalls.
Рассмотрены основные этапы интерпретации материалов сейсморазведки 3D при построении геологических моделей залежей нефти и газа. Приведены методы перевода времен в глубины и способы определения надежности структурных построений на основе сейсмических данных. Описаны особенности получения информации, необходимой для построения геологических моделей, при отсутствии или крайне ограниченном объеме скважинных данных. Большое внимание уделяется методикам исследований продуктивных отложений на основе комплексирования материалов сейсмической съемки 3D и бурения. Рассматриваются основы динамического анализа волнового поля, которые необходимы при геологической интерпретации материалов сейсморазведки 3D. Для аспирантов, магистрантов и студентов старших курсов по специальности «Нефтегазовое дело».
