| Abstract: | According to the seismic and geological differences among every oil measures in mid-deep layers at west slope in Qikou Sag, varieties of new techniques on geophysics and geochemistry were introduced, such as seismic process of target and CWS, neural network seismic microfacies cluster analysis, 3D interval velocity analysis. Taking advantage of the series of new techniques aims at predicting synthetically and quantitatively the deep gravity flow channel sandbody. Furthermore, considering the structural setting data, potential structural-lithologic traps were specified. As a result, the geological and drilling effect is obviously promoted. |
