【摘要】 随着中石油苏丹石油区块勘探开发程度的不断加深,三维地震资料连片叠前时间偏移处理已势在必行。三维连片叠前偏移处理技术是降低勘探开发风险,寻找隐蔽油气藏或遗漏的油气藏的有效途径。GRISYS处理系统作为惟一的国产地震处理软件,已形成了一套成熟的三维地震资料连片拼接处理技术。中石油东方地球物理勘探公司研究院苏丹处理中心(BPC)利用GRISYS系统的三维连片处理技术形成了一套成熟的处理流程,实现了真正的连片处理。更多还原

【Abstract】 With the Exloration&Production maturity increasing in CNPC(China National Petroleum Corporation))’s operation blocks in Sudan, application of multi-survey merging technique in 3D seismic pre-stack time migration is becoming imperative. 3D multi-survey merging pre-stack time migration technique is an effective mean to reduce E&P risk and to predict subtle reservoirs and the reservoirs which could be found out in the past. As the only domestic seismic data processing software, a mature 3D seismic data multi-survey merging processing module was developed in GRISYS processing system. Based on GEISYS system a mature 3D seismic data multi-survey merging processing workflow was also developed in Sudan Processing Centre (BPC) of GRI (Geophysical Research Institute) of BGP Inc., CNPC, the real multi-survey merging processing was realized in the workflow.更多还原
