摘要
Abstract
Dip logging can obtain high precision dip angle data near the well trajectory.This paper proposes a method of calculating the formation dip angle by the plane-wave decomposition,based on logging and seismic integration.In the exploration area with dip logging,based on the idea of Tikhonov regularization,this method was used to calculate the apparent formation dip at any point in space by logging and seismic integration,through plane-wave decomposition filter with dip logging data as constraints.The calculated apparent dip was subsequently transferred to the true dip angle and tendency,using the triangle transform.Testing on both synthetic and field data showed that the proposed method estimated the formation dip angle and thickness with an accuracy higher than that of the common plane-wave decomposition dip calculation method.This indicates its practical application value and potential for widespread use.关键词
