Research on seismic reservoir prediction technology for deeply buried marine carbonate rock buried hill in Bozhong Sag
摘要
Abstract
The marine carbonate rock buried hill fracture and dissolution pore system in Bozhong Sag is well-developed,resulting in strong reservoir heterogeneity.Due to the low signal-to-noise ratio of seismic data and the unclear seismic response characteristics of high-quality reservoirs in the B structure of Bozhong Sag,it is challenging to predict the seismic response of carbonate rock buried hill reservoirs.To address this issue,based on conventional fracture detection,this paper introduces a denoising technology based on smooth reflection intensity filtering and optimizes the ant body attributes sensitive to buried hill fractures to carry out fracture prediction,forming a high-precision post-stack fracture detection technology.At the same time,a new pre-stack inversion technology for carbonate reservoir sensitive factors with anti-lithologic interference is established by integrating P-wave velocities sensitive to fractures and pores with density parameters sensitive to lithology.High-precision post-stack fracture detection under low signal-to-noise ratio is realized,and the recognition accuracy of pre-stack elastic parameters for high-quality reservoirs under complex lithology conditions is improved.The successful application in the Bohai B structure shows that the developed seismic prediction technology for marine carbonate rock buried hill reservoirs can achieve direct prediction of high-quality carbonate rock reservoirs.The research findings can provide reference for seismic reservoir prediction in carbonate rock buried hill of the same nature.关键词
