| 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.
