摘　　要：致密油准自然能量开发前期受体积压裂区域滞留的入地液影响,近井地带能量得以补充。致密油在生产过程各阶段有不同的能量贡献,在准自然能量开发中,如何实现能量的有效接替,成为致密油藏准自然能量开发提高产能的关键。本文以长庆油田长7油藏为例,分析了X生产试验区块内产能差异的原因,揭示了致密油准自然能量开发各生产阶段产能影响因素,可为致密油藏准自然能量开发压裂、井网部署及工作制度优化提供重要参考。In the early stage of pseudo-natural energy development in tight oil reservoir, energy of near-wellbore area is replenished due to the fracturing fluid flowing into the ground.In aU stages of the productionprocess thereare 出fferentcontributions of energy.It is important to realize the effective energy to succeed for tight oil developed by pseudo-natural energy.This paper presents the case study of the Chang7 reservoir in Changqing Oilfield toandyze the causes of capacity variance in X production pilot block.It reveals the main factors that impact the capacity of different stages,and provides reference for fracturing,well network deployment and working system optimization for tight oil developed by pseudo-natural energy.
