Study Of The Seismic Attributes And Apply In The Tahe Oilfield

Seismic exploration is a good way in search of oil-gas reservoir, seismic information contains underground physical properties and liquid and so on. Seismic attributes show all the characters of seismic information, show the reservoir's physical properties and rock qualities in different aspects. With the developing of the seismic attribution technique, the kinds of seismic attributes are increasing, how to apply these attributes in oil-gas exploration and development have been a very important problem in attribution study.We known the crack-cave of carbonatite reservoir have some characters, such as, low porosity, low permeability and strong nonhomogeneity and so on. Its very difficulty in predict reservoir, now there have not been ways to solve this problem. So look for one good way or technique to predict this reservoir is very important for oil-gas exploration and development.This article base on the basic theory of seismic attribution, introduce to you about seismic attribution's development and research situation. Also I have done some analysis and research in classify mode, extract ways, attribute's choose optimize and establish reservoir relation of seismic attribution.This research base on《describe Tahe oilfield six, seven district semideep crack-cave》of Tahe oilfield. In view of Tahe oilfield's character of crack-cave of carbonatite reservoir, apply seismic attribution technique in predict crack-cave reservoir, theory be used in the practice, make use of many techniques and methods for example, direct model, cohere analysis, spectrum resolve, wave analysis and 3D visualization technique and so on. At the same time by means of wave data volume, well logging data proceed elemental quantification research to crack-cave reservoir. At last synthesize seismic, well logging and geology multidisciplinary information, propose beneficial exploration drilling.
