摘　　要：近年来,塔里木盆地塔河油田的勘探不断向深层领域延伸,勘探目标也从风化壳岩溶储集体转向断控缝洞型储集体,走滑断裂同时控制着深层油气藏的运移聚集及缝洞型储层的发育,因而如何进行断控储层预测缺乏系统性的研究,制约着塔河深层碳酸盐岩油气藏的勘探进程。基于前人的研究现状,深入挖掘塔河油田走滑断裂识别技术流程。首先,分析了塔河走滑断裂的主要样式,然后,通过地震资料的解释性处理以提高地震数据对断裂的刻画能力,最后,开展三维构造曲率及曲波多尺度相干技术的应用研究,实现了塔河油田不同尺度断裂的识别刻画,形成了塔河油田走滑断裂识别技术流程,完善了深层碳酸盐岩断控岩溶型储层预测技术方法体系。In recent years,the exploration of Tahe oilfield in Tarim basin has been extending to deep strata,and the exploration target has also shifted from weathering crust karst reservoirs to fault-controlled fracture-vouged reservoirs.Strike-slip faults control the migration and accumulation of deep hydrocarbons and the development of fracture-vouged reservoirs.Therefore,the lack of systematic study on how to predict fault-controlled reservoirs restricts the exploration of deep carbonate reservoirs in Tahe oilfield.Based on the previous research status,this paper deeply explores the strike-slip fault identification technology flow of Tahe oilfield.Firstly,the main styles of strike-slip faults in Tahe oilfield are analyzed,and then the seismic data are interpretive processed to improve the resolution of faults imaging.Finally,the application research of three-dimensional structural curvature and curvelet multi-scale coherence technology are carried out to realizes the identification and characterization of different scale faults in Tahe oilfield,and forms the technical process of strike-slip fault identification in Tahe oilfield.The technology system of deep fault-controlled karst reservoir prediction has been improved.
