高精度三维地震技术应用效果分析——以塔河油田S48井区为例
|
摘要
针对塔河油田碳酸盐岩缝洞型储层纵、横向非均质性强,目的层埋藏深度大、信噪比和分辨率较低等特点,进行了基于目标的采集、观测系统设计以及激发和接收等参数的论证和优选,建立了超深碳酸盐岩缝洞型储层高精度三维地震资料处理和解释技术系列。S48井区高精度三维地震勘探实践取得了明显的开发应用效果。
The carbonate reservoir in Tahe Oilfield is characterized by strong lateral and vertical heterogeneity,large buried depth of target formations,low S/N and resolution of seismic data.Aiming at the characteristics,target-oriented geometry design as well as shooting & receiving parameters demonstration and optimization were carried out,and high-precision 3D seismic technique series for ultra-deep carbonate fracture-cave reservoir was established.The seismic technique series was applied in S48 well area,and obvious result for development was achieved.
