摘要
Abstract
The structure of TZ Oilfield is affected by velocity distortion in fault shadow zones,leading to non-struc-tural"uplift"or"sag"distortions in seismic events.This introduces significant uncertainty in structural interpre-tation,which affects the deployment of development wells.To address this issue,this paper proposes a trend sur-face-constrained structural correction method.First,the formation attitude parameters are extracted using dip-scan-ning technology to quantitatively characterize the extent of distortion caused by velocity anomalies.Then,based on the principle that the distorted and normal zones share a unified structural trend,the method fits a trend surface from the normal zone to correct the distorted area,thereby restoring the true formation structure.This approach is ef-ficient and easy to implement,effectively eliminating the need for time-consuming and costly seismic data reacqui-sition and reprocessing.Its application in TZ Oilfield has yielded excellent results,with actual drilling errors con-trolled 5%,confirming the method's feasibility and reliability in reducing well placement deviations for develop-ment wells.关键词
