We use the result of seismic zoning map and division of seismic block, and determine the research unit of strong earthquake group, analysis the strong earthquake generic tectonic background.
Due to two different acquisition methods in the seismic block,the method of multi-parameters cluster analysis is adopted to eliminate the shortcomings of single seismic attribute in reservoir prediction and achieves good application.
In this paper, the strong seismic activity regions during earthquake preparation and immediately before earthquake are studied by "dynamic stress ellipse" method which is derived from both the centres of gravity of spatial distribution patterns of notable earthquakes in defferent time stages before strong earthquakes in North China and optimum fracture points which are obtained by "golden section" method. Through some examples, it is considered that the "dynamic stress ellipse" method can be applied t...
Based on frequent strong seismicity data in the Baton-Lijiang neibouring area of Sichuan, Yunnan and Tibet from 1980 to 1996 and combining with the distribution of active teconic zones and the historical records of strong earthquakes, this paper analyses some characteristics on strong seismicity in the neibouring area, puts forward understanding of the Baton-Lijiang seismic block in the neibouring area of Sichuan, Yunnan and Tibet and discusses the relation between the seismic ...
This paper studies the lower part of Putaohua reservoir of the high seismic block in western Talaha in northern Songliao Basin and sumurizes a set of lithologic trap identification technique for high resolution seismic.Application in production obtains a nice effect.This technique may rapidly increase the drilling success percent in lithologic reservoir exploration and has a good prospect.
