Sedimentary characteristics and reservoir distribution regularity of Tuo 71 area in Shengtuo oilfield

In view of the fracture system complexity of Tuo 71 area in Shengtuo oilfield,3D seismic data reprocessing was adopted.In combination with curvature analysis,the fracture system has been accurately depicted.In view of the glutenite reservoir characteristics,such as multiphase mixed sedimentation and quick horizontal change,by use of the conventional logging curve,the comparison difficulty is big and the fan reservoir distribution regularity can not be made clear.With integrated application of wavelet transform,clustering analysis and the formation of INPEFA curve reconstruction technology,the fine stratigraphic correlation and reservoir distribution regularity have been achieved and made clear.
