大老爷府区块油藏属于低孔、低渗油藏.在油藏地质特征研究的基础上,针对研究区开发过程中出现的单井产量递减严重、含水上升快、高含水油井增多等情况,本文从动态、静态2个方面分析了大老爷府单井产能影响因素,提出针对性的建议来充分挖掘油层潜力,以达到降低递减率提高单井产量的目的. Dadioyu block reservoir belongs to low-porosity and low-permeability reservoirs.Based on the study of reservoir geological features, aiming at the serious single-well productivity decline, rapid increase of water cut and increase of high water cut oil wells during the development of the study area This article analyzes the influencing factors of single well productivity of Dadufu from two aspects of dynamic and static state and puts forward some suggestions to fully tap the potential of the reservoir so as to achieve the purpose of reducing the decline rate and increasing single well productivity.
