Abstract:
Regarding the characteristics of multiple provenances, rapid sedimentation rate, large sedimentary thickness and multi-stage superposition of the glutenite fans on the the steep slope in northern Guojuzi subsag of Chezhen sag, Jiyang depression, and based on the analysis of core and FMI logging images and optimization of classification methods for various sedimentary sequences, a comprehensive classification method for glutenite sedimentary sequences is presented. Firstly, core and FMI image are used to classify the glutenite sedimentary sequence and calibrate the relationship between lithology and electrical property; then methods of shale interlayer identification, curve recombination constrained by seismic data and reflection coefficient calculated with logging curve and diplog data are applied to classify sedimentary sequence. Finally, seismic time-frequency analysis and wavelet transform method are used to verify and replenish the comprehensive classification. Using the above method, Sha-1 member on the steep slope of northern Guojuzi subsag can be divided into 3 sedimentary sequences, Sha-2 member into 4 sedimentary sequences, the middle and lower sections of Sha-3 member can be classified into 12 sedimentary sequences and Sha-4 member into 5 sedimentary sequences.
