摘　　要：胜利油田整体进入开发中后期,精细油藏开发与进一步提高油气采收率对开发地震技术提出了更高的要求。但由于济阳坳陷常规油藏受埋深差异大、多期构造运动、沉积类型多样等因素影响,储层展布与连通关系复杂;同时受到地震识别能力的制约,部分油藏井-震关系不明确,限制了储层精细表征精度。针对胜利油田不同类型常规油藏开发需求,通过实践形成了一系列开发地震技术,包括多方法集成的中浅层河流相储层预测技术、断棱精细刻画技术与多属性组合的一体化复杂断块油藏断裂系统精细描述技术、中深层低渗透储层预测技术、“断-缝-溶复合储集体”多参数融合的潜山油藏储层描述技术,为油藏开发提供了有力支持。但随着开发目标油藏“更深、更薄、更小”并逐步拓展至非常规油藏,对开发地震技术提出了更高要求和挑战,需要推进处理解释一体化进程,强化岩石物理理论研究,推广OVT域叠前反演在多类型油藏描述中的应用,攻关复杂断块-岩相油藏精细描述技术,突破井-地联采与重磁电震联合技术瓶颈,实现人工智能技术在开发地震领域的应用,进一步提高油藏开发水平。Shengli Oilfield has entered the middle and later development stages,and higher requirements for development seismic technologies have been set to develop reservoirs and further enhance oil recovery finely.The distribution and connectivity of conven-tional reservoirs in Jiyang Depression are complex due to different buried depths,multi-stage tectonic movements,various sedimen-tary types,and other factors.At the same time,constrained by seismic recognition,the well-seismic correspondences of some reser-voirs are unclear,limiting the accuracy of fine reservoir characterization.In response to the development needs of different types of conventional reservoirs in Shengli Oilfield,a series of development seismic technologies have been formed through practice.These technologies include multi-method integrated reservoir prediction technology for middle and shallow fluvial facies reservoirs,inte-grated fine description technology for fracture systems in complex fault block reservoirs combing fine fault edge depiction and mul-tiple attributes,prediction technology for middle-deep reservoirs with low permeability,and description technology of buried hill reservoirs fusing multiple parameters of“fault-fracture-dissolution composite storage space.”These technologies provide strong sup-port for reservoir development.However,as the target reservoirs for development get deeper,thinner,and smaller and expand into unconventional reservoirs,the development seismic technologies faces higher requirements and challenges.It is necessary to accel-erate the integration process of processing and interpretation,strengthen the theoretical research of rock physics,promote the appli-cation of OVT domain pre-stack inversion in the description of multi-type oil reservoirs,tackle the fine description technologies of complex fault block-lithofacies reservoirs,break through the technical bottleneck of well-ground joint acquisition and gravity-magnetic-electric-seismic technology,and realize the application of artificial intelligence technolog
