【摘要】 三维VSP正在成为油气田勘探开发的一项重要技术。为了评估特定地质环境下三维VSP所能解决的具体地质问题的能力以及为了选择最佳的三维VSP采集参数和处理解释流程,长安大学应用地球物理研究所承担了国家863项目的子课题——《三维VSP模拟仿真研究》。本文是作者作为课题组主要成员之一参加这一课题研究工作后,结合攻读硕士学位的要求,在自己研究工作和课题组其他成员研究工作基础上写成的一篇论文。全文分成三部分:第一部分概述三维VSP技术的研究目的和意义,列出三维VSP的研究内容,评述了国内外三维VSP技术的发展,列举了自己在三维VSP模拟仿真项目研究中所做的工作。第二部分,比较仔细地讨论了三维VSP模拟仿真的方法原理。第三部分给出了几种简单地质问题模拟仿真研究和垦71井区做三维VSP模拟仿真研究的例子。第四部分是通过研究得出的结论。模拟仿真的结果已被随后接着进行的三维VSP实际资料采集、处理所采用。同时也表明三维VSP模拟仿真研究的确是一种科学的、节省高效的、要求条件少的、重复性好的研究方法,可以为实际三维VSP地震资料的采集设计、数据处理和资料解释提供指导和依据。更多还原

【Abstract】 3D VSP is becoming one of important techniques in oil-gas field exploration and development. In order to evaluate the power of 3D VSP settling specific geological problems and choose optimal 3D VSP acquiring parameters and the progress of processing and interpretation, the Application Physical Geography Graduate School in Chang’an University undertakes national 863 subtask--3D VSP simulation research. After my taking part in the research task as one of the main researchers, combining with the request of the master paper, I finished the paper based on the works of myself and other researchers. It consists of four parts: the first part summarizes the objective and significance of 3D VSP technique research, the content of 3D VSP research, and states the development of 3D VSP technique inland and overseas, enumerates what I have done in the project. The second part discusses very carefully the methods and theories of 3D VSP simulation. The third part gives the example of 3D VSP simulation in ken₇1 well region. The fourth part presents the conclusion of the study. The results of 3D VSP simulation study have been used for 3-D VSP acquiring and processing later. It is identified to be really a scientific, saving, efficacious, less conditions and good repetition research method. 3D VSP can offer a guidance and gist for acquiring design , data processing and information interpretation of practical 3D VSP data.更多还原
