【摘要】 自从赵鹏大院士提出油气地质异常理论以来,中国地质大学的有关研究人员已经开展了多项油气地质异常分析研究工作,迄今为止已经在油气勘探的各个领域进行了大量的实践研究工作,并已取得了很好的研究效果。但现有的研究都局限于研究人员独立进行分析工作,各个研究模块彼此割裂,各个研究领域的数据无法实现共享,研究流程也尚未系统化,研究成果的表现形式也欠多样化,这影响了油气地质异常理论与方法的更大发展。本文在大量研究前人研究成果的基础上,首次提出了三步式油气地质异常分析流程——即由点及线,最后到面的研究方法,最终确定有利的勘探区域。本文以该思路为基础,设计了油气地质异常分析系统,并通过可视化语言结合三维显示等新技术将其实现。最后,使用该系统对临清坳陷德南洼陷进行了有利勘探区域的圈定,同时也检验了油气地质异常分析系统的可靠性和实用性。本次研究主要取得的主要新认识如下: 1) 首次建立了油气地质异常三步式分析流程——点、线和面分析流程,通过将该思路与多种常规目标研究流程进行了比较,证明该方法在油气勘探的多种目标研究中具有很好的适用性和通用性。2) 建立了综合异常权重系数法,该方法将各种油气地质异常计算参数按照研究要求进行综合异常计算,能够得到更加理想的综合异常研究结果。3) 本次研究还按照勘探数据来源、系统计算的需要,建立了基于SQL Server的油气地质异常数据库。4) 本次研究使用了ActiveX 控件、OLE 自动化服务器等多种程序设计技术,使得研究成果具有多样化的表现形式。5) 系统提供了基于GIS 技术的井位信息查询功能以及BP 神经网络测井、地震预测解释模块,后者可作为常规异常分析手段的补充。6) 本次研究好识别出德1 和德6 井地层界线,line97 测线的地层界线以及研究区异常区域,在德南洼陷圈定出德1、德6 井附近区域为一个有利的勘探区域。更多还原

【Abstract】 Since Oil&Gas Geology Anomaly Theory was founded by Zhao Pengda in 2000, technology of oil geology anomaly has been applied in several researches on oil&gas exploration and all of them have got good expected effect. However, the present researching works are mainly focused on separate study on single aspect, which make the studies separated from each other, as well as study procedures. Also, data in each study procedure can not be shared freely among different studies that has made the whole research can not be a wholly stream of studying. Furthermore, the result showing forms are also in dull statues, all of which have made the research work of oil geology anomaly analysis easier for operation. Based on a great amount of previous studies, a new method of three-step analyzing procedure of oil geology anomaly was firstly founded, which includes methods from points, lines and surfaces analysis, and finally determine the favorite prospecting area. One software in accordance with that theory has also been set up via visual programming language Broland CB6 with technologies like 3-D display. Furthermore, the writer uses the software to determine the favorite area of exploration in De Nan hollow, Lingqing, as well as work of verifying the reliability and feasibility of the software. Main new suggestions are provided in the thesis including the following: a) Firstly set up three-step oil geology analysis procedure, which include point, line and surface analysis procedure. Compared with normal target analysis procedure, the new procedure was proved to be suitable and general in research of multiple target analysis for oil&gas exploration. b) Set up a new method of comprehensive weight-index, which can realize comprehensive calculation using all kinds of parameters during studies and it can also get ideal comprehensive analysis result. c) A new oil&gas exploration database based on SQL Server was set up in accordance with the requirement of data source and system calculation.更多还原
