查询词典 seismic

The maximum run-out distance is 3200m. The three cases are studied from the Niuquangou rockslide-debris flow at the south west segment of the main seismic fault, the Chengxi rockslide at the middle segment of the main seismic fault and the Donghekou rockslide-debris flow at the north east segment of the main seismic fault.The three cases illustrates following common characteristics:(1)parent rockmass is broken under long geologic processing and weathered;(2) Rockmass was separately expanded and thrown under long-period strong ground vibration in which the vertical motion was predominant along the main seismic fault;(3)sliding mass was crashed at the exiting zone and transferred to fragment material;(4) The secondary landslide was triggered underneath the exiting zone due to the powerful crashing and shaving processes that provides more mass to debris body and cushion shape;(5) The a long run-out distance fragment flow is occurred under air layer lubrication. The air layer was pressed and turbulently flowed in the narrow-shaped valley, or laminarly flowed in the extensive flatland.

In order to clearly recognize the geophysical response of carbonate reservoir,based on preliminary recognition of Ordovician carbonate reservoir under the basal surface in Tahe oilfield,some regular vug models and random arranged vug models were designed and built. The variable-grid finite difference method was used to simulate the seismic wave propagation in these models. Then,the seismic records of the models were analyzed and the effect to seismic reflections caused by vug is studied. The impact rule of regular vug scale and random arranged vug density on seismic attributes was obtained.
