The management work data of oil - field earthquake exploration and oil - well position, which has not only data of current space position, but also entitative attribute data describing, have great capacity, traditional cad graphics describing the data plus the model database managing mode ca n ' t already adapt the modem exploration with well geography information for management work demand, so it is necessary to realize the unique management of exploration and oil - field well space data and attribute data use advanced geography information system ( gis ) technique, this thesis is based on the excellence ' s table ' s top geography information system - the maplnfo software, using the second process technique, the digital relief map and tectonic map as the base map, the earthquake exploration database as the original data, established the gis of the exploration and oil - field well in the area of the liaohe oil - field, realize visualization management, it provides a reference thereunder for the earthquake exploration deplo ying the workload and proceeding the technique design, and completed lots of practical work
油田地震勘探與油井井位管理工作數據量大,既有空間位置數據,又具有實體的屬性描述數據,傳統的cad制圖+屬性數據庫管理模式已經不能適應現代勘探和井位管理工作的需要,採用先進的地理信息系統( gis )技術,實現勘探和油田井位空間數據和屬性數據的統一管理是必然的趨勢。本文以優秀的桌面地理信息系統mapinfo軟體為開發平臺,在此基礎上進行二次開發,以數字化地形圖、構造圖為載體,以地震勘探數據庫為數據源,建立了遼河油田范圍內的地震勘探和油田管理信息系統,實現了數據的可視化管理,為地震勘探部署工作量、進行技術設計,提供了圖形和數據的參考依據。並完成了很多實際工作。Hi this thesis, the technique of detector array is used to obtain the location of anomalous infrasound, it is the basic of the study of prediction of earthquake. to derive useful information by using spectrum analysis on infrasonic signal. then combing with other methods a forecast could be made
本課題主要是利用數字技術,採用用傳感器陣列計算異常次聲波波源的方位,這是今後預測震中位置研究的前提;並對次聲信號進行頻譜分析,提取有用的關于臨震次聲方面的信息,再結合其他的預報方法,作出準確的地震預報。( 3 ) based on the analyses results of simple inference method and seismic focal mechanism and on the statistic results of measured geostress data, the direction of principal stress was derived and based on the analyses results of macro geological estimate and on the statistic results of measured geostress data the magnitude of principal stress was derived too. the influence of rapidly down - cutting of yellow river on geostress field of studied zone was discussed. then the evolution of geostress field accompanying with the down cutting of yellow river and was simulated with fem and the spatial distribution features of geostress were discussed
根據簡易推斷法、地震震源機制分析法以及地應力實測資料統計分析結果,綜合確定了工程區的主壓應力方向;運用地質宏觀判斷法並結合地應力實測資料的統計分析結果對地應力的量級進行了綜合評價,並進一步討論了黃河快速下切對研究區地應力場的影響;運用有限元法模擬了研究區地應力場的形成過程,並探討了地應力的空間分佈規律。In addition, effects of several factors such as local site conditions, focal mechanism, epicentral distance and seismic magnitude on these parameters are discussed, and several significative results and conclusions are obtained. in all records there are about 1 / 3 vertical ground motion ’ s peak acceleration bigger than 2 / 3 of the corresponding horizontal one, so the action of vertical ground motion should not to be underestimated. vertical design response spectrum equals that the horizontal design response spectra times 65 % is probably unsafe when period is short, and suggest adopting different coefficients when at different periods
本文基於對大量歐洲強震記錄的研究,分析了地震動豎向與水平向分量在峰值加速度、反應譜值、頻譜周期等參數方面的差異,以及這些參數與場地、震源機制、震級和震中距的關系,得到了以下有意義的結果和結論:在本文分析的地震記錄中大約1 / 3的記錄加速度峰值比大於2 / 3 ,豎向地震動分量的作用不可低估;在短周期,豎向地震動影響系數的最大值僅取為水平向地震動影響系數最大值的65 %是偏於不安全的,可以考慮按周期分段採用不同的折減系數;我國現行抗震規范中設計反應譜特徵周期的取值偏低,可能是偏於不安全的;豎向與水平向地震動分量卓越周期的比值在0 . 7 - 0 . 9之間,豎向設計反應譜的特徵周期應有單獨規定。In order to make the studying about the seismic exploration method possess systematic nature and the ability of tackling key problem in front - zone of mountain, we have done the research work of tackling key problem aiming at the field gathering technology of seismic exploration of the complicated structure belt ( the construction of underground and the earth ' s surface condition are complicated ) of front - zone of mountain in this text, and a large number of relativity trials by the close combination of production and scientific research, summarized a set of field method of the complicated structure belt of front - zone of mountain, adjusted both of trial factor and construction factor of the field gathering in time, achieved finally the goal of making its structure character clear
近幾年來,隨著地震勘探裝備和技術的改進,野外資料採集技術有了新的進展,主要表現為多種震源聯合激發方法(井炮和大噸位可控震源) ,基於地表條件及表層調查基礎上的激發選點方法,小道距、長排列、高覆蓋接收方法,基於模型的「分段、分線、分區」觀測系統目標設計方法等,取得了顯著的勘探效果。為了使山前地震勘探方法研究具有系統性和攻關性,通過本文對復雜山前復雜構造帶地震勘探的野外採集技術進行攻關研究,進行了大量具有針對性的試驗,總結出了一套山前復雜構造帶野外施工方法,最終達到了搞清復雜山前復雜構造帶山前復雜構造帶構造特徵的目的。In order to calculate synthetic seismograms in a layered half - space with the sources and the receivers at close or same depths, an efficient numerical integration method - the peak - trough averaging method ( ptam ) is proposed, based on the repeated averaging method
