摘　　要：YCH油田储集层以特低孔、特低渗透储层为主。本文根据YCH油田中油藏的实际地质情况和开发特征,通过选取该油田典型研究工区内相对完整的井网区域,以低渗透油藏典型区块为基础,系统研究了启动压力梯度对产量递减规律的影响。The reservoirs are mainly lower permeable and lower porosity in YCH Oilfield. In this paper, according to the actual geology and the development of the YCH Oilfield, the influence of a threshold pressure gradient on the production decline law has been studied systematically based on the typical blocks in the lower permeable reservoirs by selecting the relatively complete well pattern areas in the typical study area in the YCH Oilfield.
