【摘要】 山前复杂构造带是西部新区油气勘探的主攻领域之一,西部山前带由于其特殊的表层地震地质条件和深层复杂地质结构,造成静校正问题突出、地震波场复杂、地震资料信噪比低。针对这些难点提出了西部山前带观测系统设计方法,即基于真实地表的综合模型和叠前成像效果、结合CRP分析技术的观测系统设计技术,利用该技术在哈山西三维区块进行了观测系统优化设计,获得了较好的资料效果。更多还原

【Abstract】 The complicated piedmont belt is the main field for oil and gas exploration in new exploration regions of West China.The particular surface geological conditions and complicated deep geological structures of these regions cause outstanding problems such as static correction,complex seismic wave field and low SNR seismic data.Aimed at solving these difficulties,this paper puts forward the design of seismic geometry in western piedmont belt,which is based on the comprehensive real surface model with pre-stack imaging effect in combination with the design technology for the observation system of CRP analysis technology.This technology was used in Hashan 3D block for optimization design of the observation system,with fairly good results obtained.更多还原
