The reservoirs mainly are structural lithologic composite reservoirs. According to the petroleum geologic characters of the region and fully using 3 D seismic data,the paper uses 3 D visualization interpretation technique,coherent body and stratigraphic dip detection technique,reservoir prediction technique and multi contribution model constrained inversion for interpretation of main targets and appreciation of traps.
Comparing 2-D and 3-D cross line,filtering two steps F-K,scanning seismic coherency cube and time slices,and contrasting with adjacent area show that the probability of seismic footprint could be negated.
By analysing and inter preting the actual data, we may find coherency cube technology is an available f ault's interpret method. It can improve the interpretable precision and shor ten the exploration period.
Aimed at the circumstances,we strengthen our efforts in studying reservoir feature,set up a set of techniques studying Guangrao buried hill type reservoir,that is press field analysis,coherent volume calculation,logging constrained inversion and pattern recognition,define the distribution area of favorable facies belt for buried hill type reservoir and optimize 3 designed wells.
On a basis of 3 D high resolution seismic data acquisition and processing and through integrative use of coherent volume with optimum frequency band,integrative detection of dips and fault edges,analysis of sedimentary microfacies and seismic inversion etc. ,the paper gained the following major results: the rule of spatial distribution of faults is known,total 135 faults are interpreted ( only 29 faults in 2 D data );
This survey paper presents the first theoretical framework capable of unifying, into a single coherent body of knowledge, a diversity of shapes associated with elastic bows, car bumper-bars, molluscan shells, even flower-buds and pine-cones.
Many sociologists believe in the myth of a "Chicago School," a unified and coherent body of thought and research practice carried on at the University of Chicago from the 1920s through the 1960s.
This concept has a legitimate role to play in science only if the colloquial usage relates to a coherent body of evidence.
We examine the role of tasks that have the intended effect of teachers re-conceiving the mathematics they teach as comprising a coherent body of meaningful ideas.
Having avoided the Scylla of mimicking American empiricism and the Charybdis of philosophical devolution, French sociology stands as a small but coherent body of research, the quality of which is frequently very high.
