摘要

双复杂地区三维地震勘探面临地表、地下地质条件复杂,采集观测激发、接收困难等问题,极大地影响地震资料品质。提出的双复杂地区三维地震勘探采集设计方法是通过波动方程正演、基于地理信息采集观测优化、采集观测波动方程照明分析、目标目的层能量均衡优化设计等技术的综合应用。该方法在辽河油田DPF地区进行了实际应用,达到了提高采集资料品质、改善成像效果的目的。
Double condition complicated area confronted with many problems,such as complicated surface and geological condition,shooting and receiving conditions were difficult,and those problems greatly influenced the quality of seismic data.An acquisition design method of 3D seismic exploration in double complicated area was proposed through wave equation based forward modeling,observation optimization based on geographic information,observation based on wave equation illumination analysis,optimization design based on energy balancing.This method is applied in DPF Area of Liaohe Oilfield,and it improves the quality of seismic data and imaging quality.
