Abstract

The papers dedicated to the procedures of solving direct problems in seismic exploration of fractured formations are considered in this review article. The fractured formations are known to be potential hydrocarbon reservoirs, which are being studied actively at the present time. Due to high cost of field prospecting works, the numerical simulation is an important part in such research, leading to a significant decrease in financial and time expenditures. The papers focusing on conventional popular practical modeling methods based on the use of effective models are considered. A significant part of this work also deals with the papers that use the procedures developed by the authors to solve the formulated range of problems. These procedures are based on a grid-characteristic numerical method with interpolation on unstructured triangular (in the 2D-case) and tetrahedral (in the 3D-case) meshes. The grid-characteristic method most accurately describes the dynamical processes in exploration seismology problems, because it considers the nature of wave phenomena. The used approach allows making the correct computational algorithms at the boundaries and contact boundaries of the integration domain. An important part of this article describes the different models of fracturing. The results of mathematical modeling by the developed procedure, which are presented in the authors’ papers, are also considered. The important practical conclusions made in the considered papers are presented.

网格特征方法在裂隙地层地震勘探直接问题求解中的应用(综述)

摘要

这篇评论文章考虑了专门针对解决裂缝地层地震勘探中直接问题的程序的论文。已知这些裂缝地层是潜在的油气藏,目前正在积极研究中。由于现场勘查工作的高昂费用,数值模拟是此类研究的重要组成部分,从而导致财务和时间支出的显着减少。考虑了基于有效模型的使用,着眼于常规流行的实用建模方法的论文。这项工作的重要部分还涉及使用作者开发的程序解决提出的问题范围的论文。这些过程基于网格特征数值方法,对非结构三角形(在2D情况下)和四面体(在3D情况下)网格进行插值。网格特征方法考虑了波浪现象的性质,因此最准确地描述了勘探地震学问题中的动力学过程。使用的方法允许在积分域的边界和接触边界处做出正确的计算算法。本文的重要部分描述了压裂的不同模型。作者的论文中介绍了通过开发的过程进行数学建模的结果。提出了重要的实践结论,在考虑的文件。网格特征方法考虑了波浪现象的性质,因此最准确地描述了勘探地震学问题中的动力学过程。使用的方法允许在积分域的边界和接触边界处做出正确的计算算法。本文的重要部分描述了压裂的不同模型。作者的论文中介绍了通过开发的过程进行数学建模的结果。提出了重要的实践结论,在考虑的文件。网格特征方法考虑了波浪现象的性质,因此最准确地描述了勘探地震学问题中的动力学过程。使用的方法允许在积分域的边界和接触边界处做出正确的计算算法。本文的重要部分描述了压裂的不同模型。作者的论文中介绍了通过开发的过程进行数学建模的结果。提出了重要的实践结论,在考虑的文件。本文的重要部分描述了压裂的不同模型。作者的论文中介绍了通过开发的过程进行数学建模的结果。提出了重要的实践结论,在考虑的文件。本文的重要部分描述了压裂的不同模型。作者的论文中介绍了通过开发的过程进行数学建模的结果。提出了重要的实践结论,在考虑的文件。
