Elimination Of The Overlying Complicated Geologic Tectonic Disturbance To The Underlying Strata Imaging

Because of the relative scarcity of oil resource, and the growing demand for oil, oil exploration has gradually moved from looking for simple configuration reservoir to complex fault block reservoirs, hill reservoirs, subtly reservoirs. These complex underground geological structural features led to the complexity of the resulting seismic exploration in seismic wave field, which greatly increased the difficulty of accurate imaging of complex structures, so the presence of the complex geological structure of the migration imaging have higher requirements. Now, with the increasing degree of oil and gas exploration and deepening understanding of the geology, seismic exploration goals are more subtle, seismic data imaging quality and accuracy requirements are also increasing. The accuracy of seismic imaging of complex subsurface structures, the accuracy of processing has become an important part.In the area of complex geological structure of the acquired seismic data processing records, since the reflected wave received by the complex geological structure beneath the geologic complex formation structure, the consequence become to complexity, therefore, the underlying image has been strongly interfered. In seismic data processing chain, this underlying strata migration imaging cannot reflect the true geological lithology changes. Aim of the task of this paper is to eliminate the overlying geologic tectonic disturbance to underlying strata imaging.The data presented herein is the data processed after seismic data processing. Through this data remove the overlying complex structures’ affection in the seismic migration imaging.
