摘　　要：致密油藏作为近年主力产建及开发层系,是后期稳产增产的主战场,目前,X区长8油藏面临着渗透率低,裂缝发育,注水开发主向井见水、侧向井不见效,地层能量下降快,递减大等问题,通过对开发区块的特征及矛盾进行研究,总结出一些关键治理及调整技术,为后期相类似油藏高效稳定开发提供一定借鉴。As the main production and development layer in recent years,tight oil reservoir is the main battlefield of stable production and increase in the later period.At present,the X area Chang 8 reservoir is facing problems such as low permeability,fracture development,water breakthrough in the main well of waterflooding development,ineffective lateral wells,rapid decline in formation energy and large decline.By studying the characteristics and contradictions of the development blocks,some key management and adjustment technologies are summarized,which can provide some reference for the efficient and stable development of similar reservoirs in the later stage.
