Favorable reservoir prediction and connection model biulting of thick glutenite sediment in basin steep slope zone

Abstract

The glutenite deposit in the Dongying basin's dip slope zone, which is influenced by Palaeogeomorphology, has a large deposit thickness, a diverse lithology that varies rapidly in the horizon, and a difficult sand body superposition. Due to the resolution of seismic data and the vast variances across sedimentary, the connection of sand bodies cannot be represented using a simple way, and it is difficult to analyze the link regulation between water injection and oil extraction. The seismic facies of distinct glutenite sediments may be determined using well data and the properties of glutenite deposits in nearshore subaquatic settings. Several inversion techniques are used to construct the low and high-frequency component, resulting in a high-quality sand prediction result with reasonably high resolution that adheres to sedimentary laws, using seismic facies analysis as a constraint and making full use of good data. The management of sand spread and connection may be defined based on the sand prediction result, and sand body connection models of different sedimentary surfaces can be created and used to change the well water intrusion.
