摘要
潜山油气藏是辽河坳陷重点勘探领域之一,其储集空间以微裂缝、微孔隙为主,受此影响,潜山内幕的地震资料波场复杂、反射特征不清,传统的反射波成像精度低,不能满足实际需求,制约了对潜山内部结构的认识和潜山油气勘探。针对该问题,提出一种全新的散射波成像技术,该技术主要通过压制地震反射波能量、加强散射波能量,实现地震资料更高分辨率的成像;该技术能够对潜山内部的地震弱散射信号成像,进而实现对复杂地质背景下潜山内部裂缝细节的精细研究和描述,并应用于辽河油田曙光潜山带复杂构造研究中,取得了明显效果,可为同类地震资料处理提供一定的借鉴。
Buried hill reservoir s are considered as one of the major hydrocarbon exploration areas in the Liaohe Depression,and the corresponding reservoir space is dominated by microfracture and micropore.The seismic data inside the buried hill is characterized by complicated wave fields and unclear reflections.Traditional reflected wave imaging is limited in the internal structure identification and buried-hill hydrocarbon exploration.A new scattered wave imaging technology was proposed to realize high-resolution seismic data imaging by suppressing seismic reflection wave energy and strengthening scattered wave energy.The weak seismic scattered signal inside the buried-hill can be imaged to characterize the fracture properties within the buried hill under complex geological setting.This technology was successfully applied to characterize the complex structures of Shuguang buried hill zone in Liaohe Oilfield,which could also provide certain reference for the similar seismic data processing.
