There are a lot of small oil reservoirs with low production,low permeability and low deposit in the western peripheral area of Daqing Placanricline, which the geological conditions are very complicated. In reservoirs, the conditions of structural trap are bad, the small faults and microstructure are often seen; reservoirs develop badly, and its distribution isn't stable, and the petroliferous trap are controlled by many factors, so the distribution of gas,oil and water is very complex.Based on the practice above, during the drilling, the application of seismic predication technology to the rolling exploration and development have used to improve the reservoir description level and development benefit of oil fields.In the article, the technology of the integration of development seismic processing have been used to interpret faults and tectonics, establish the geological model of fine structure, and improve the precision of structural description;The faults identify technology being used, which identifies small faults; using the method of amplitude analogy, it can predict reservoirs;Based upon traditional seismic attribute optimizing technology, developed a method of seismic attribution optimizing with well data classification and seismic attribution linear regresstion technology near well, the precision of reservoir prediction can be enhanced , The logging constrained inversion technology have been used to predict reservoir parameters among wells, all technologies are used together to struct the drilling work.
