Abstract: The shallow Neogene composite channel sand bodies are important reservoirs in Bohai oilfield. Based on well logging-to-seismic integration data of Kenli 6-1 oilfield in Laibei area,gather optimization was carried out to improve the amplitude-preserved properties of pre-stack gathers,and fine seismic description and fluid detection of thin interbedded sand bodies were completed. The results show that:(1)The AVO correction method in time-frequency space domain with low-frequency constraints effectively improves the AVO amplitude-preserved properties of pre-stack gathers in the study area.(2)The iterative frequency-divided stochastic inversion technology constrained by three-dimensional sand to stratum ratio realizes fine characterization of the superposition relationship of Neogene composite sand bodies and the accurate calculation of reservoir thickness in the study area. (3)The fluid detection technology with three-parameter constraint can weaken the influence of non-hydrocarbon anomalies,enhance the matching degree between seismic fluid anomalies and tectonic high and low information,and greatly improve the coincidence rate of seismic fluid detection in the study area,so as to improve the success rate of lithologic reservoir exploration.

Key words: composite channel sand body, AVO correction, random inversion, fluid detection, lithologic reservoir, Neogene, Bohai oilfield
