堆積盆内工業地震イメージング プロジェクトのほとんどの目的は、炭化水素貯留層を探索することです。近年、炭化水素の探査は塊状の洗面器の多くはかなりの石油とガス貯留層を持っているので、火成岩類の多量を含む流域に拡大しています。ただし、塊状の流域における火成岩類のインタ フェースが、地震データ処理、一連の減らされたエネルギー伝送、減衰、干渉効果、屈折、散乱1など、さまざまな攻撃による課題。したがって、油田会社は地震イメージング2,3,4にこのような「否定的な影響」を減らすこと努力を注いでいます。

data processing methods for 3d seismic imaging of subsurface volcanoes: applications to the tarim flood basalt

形態と配管システムの構造は、噴出量および玄武岩溶岩のスタイルに重要な情報を提供できます。地下地質体を勉強する最も強力な方法は、産業の三次元反射地震学的イメージングを使用することです。ただし、地下の火山をイメージするための戦略は非常に異なっている石油とガス貯留層の。本研究で我々 は不透明度レンダリング技術により敷居を視覚化する方法と時間をスライスして、コンジットをイメージする方法を説明するために北部タリム盆地、中国からの地震データ キューブを処理します。最初のケースでは、分離したプローブ敷居の間の接点をマーキングと被覆層、耐震の視野によって地震のキューブから敷居を抽出する不透明度レンダリング技法を適用します。流れ方向は、ドームの中心から縁に結果の詳細な敷居形態を示しています。2 番目の地震キューブにしておりますタイム スライス画像の導管、, 岩内のマーク付きの不連続に対応します。異なる深さで得られたタイム スライスのセットは、タリム川洪水玄武岩が別のパイプのような導管によって供給される中央の火山から噴出したことを表示します。

Data Processing Methods for 3D Seismic Imaging of Subsurface Volcanoes: Applications to the Tarim Flood Basalt

地下の火山の 3 D イメージングのデータ処理方法: タリム洪水玄武岩のアプリケーション

The overall goal of this procedure is to illustrate how to extract sills and conduits of subsurface volcanoes from seismic data cubes. This method can help answer key questions in volcanology, as the structure and the morphology of the plumbing systems can provide key information about eruption rate and the style of basaltic lava fields. The main advantage of this technique is that the 3D structure of subsurface volcanoes are extracted from industrial 3D reflection seismology images for overall exploration.In this study, we process seismic data cubes from the Tarim Basin in China, to illustrate how to visualize sills and the conduce of subsurface volcanoes. To begin the calculation, first import the seismic acoustic data cube into an appropriate data processing program. Display the data in 2D and 3D, and adjust the data set appearances, as desired.Then open the settings menu for the well of interest, and open the Time sub menu. Select Create new and name the time log. Use the velocity function DT data to create a one-way time log from the acoustic log.Next, in the 3D data window, select TWT, to display the data in the two-way time domain. Set the newly-created one-way time log as the active time-depth relationship. Select the wired logs of interest to display their seismic profiles in the 3D window.Then, use the Manipulate plane tool to adjust the profile, until it intersects the well. Next, in the Seismic tree, uncheck one plane. In the Well tops tree, select the corresponding well filter and set it to surface.Enable annotations for the Well tops and verify that wired log domains are displayed with the seismic profile. Next, open the Seismic well tie menu. Set the study to Integrated seismic well tie and select the well of interest.Set the TDR to the calibrated one-way time log. and select the seismic data cube. Select any log from the RC calculation method options and fill in the corresponding parameters.Use the Wavelet tool box to create or edit a Ricker wavelet. Click OK to generate the synthetic seismogram. Repeat the process if the synthetic trace does not satisfactorily match the seismic data.Then open the one-way time log created from the acoustic log. Identify a real continual seismic horizon that intersects the well of interest. Add a small increment of time to the Well Log, to adjust the depth of the synthetic trace.Open the calculator tool. Compare the Well log and the seismic horizon. Continue adjusting the Well log in this way to maximize the overlap of the high amplitude reflectors in the synthetic and real traces.The synthetic seismogram from the wired log we have force features. Because the log imaging does not perfectly fit with the burgherwalls. Regional geological information, and a vertical seismic profile are needed to correct and optimize the seismogram.Open the Seismic interpretation menu, and select Insert a Horizon probe. In the individual probe settings, open the Horizons tab, and select two high amplitude surfaces encasing the sills of interest. Select the new probe to display a seismic cube in the 3D window.Open the probe settings, and select the opacity tab. Use the seismic amplitude histogram, to decrease the opacity of low amplitude reflections, leaving only the basaltic sills of interest. Adjust the histogram repeatedly, until the desired shape of the interested geobody of igneous rocks, is achieved.Next, open the Volume attributes menu. Set the category to Structural methods and the Attribute to variance. Set the seismic cube as the input.Enable the Realize option to improve performance and run the process. Choose the variance cube, and select Insert time slice intersection. Use the Manipulate plane tool, in the 3D window, to move the slices to optimize the visualization of discontinuities, corresponding to vertical feeding conduits.Repeat this process with the Seismic amplitude cube. Adjust the two-way time, and vary the slicing depths, to find the best visualization parameters for the data. A 3D seismic data cube, from the Northern Tarim Basin, was processed with this technique.Separated lava lobes were observed in the extracted horizontal sills, suggesting that the lava flow, moves from the dome center to the rim of the dome. Time slices were obtained from the seismic cube, and from a variance data cube to visualize vertical volcanic conduits. Different slicing depths were required for the seismic and variance cubes to visualize the conduits.While attempting this procedure, remember to obtain adequate knowledge of regional geology, the stratigraphic framework, and the characteristics of the marker horizons. After it's development, this technique paved the way for researchers in the field of volcanology, to investigate the 3D structures of the subsurface parts of ash in volcanoes. After watching this video, you should have a good understanding of how to image subsurface volcanoes using our industrial, 3D seismological data cube.
