摘要(Abstract):
针对大庆外围低、特低渗透油田的探井试油及开发动态资料, 从裘皮公式的基本原理分析入手, 探讨了探井试油阶段和开发稳产阶段的产量、产能关系, 对比了滞后注水开发与同步注水开发的开发效果, 得出以下认识: 一是探井试油阶段和开发稳产阶段的产量关系是离散的, 而产能关系相关性极好; 二是同步注水开发情况下开发稳产与探井试油产能比、开发稳产期与投产初期产量比要明显高于滞后注水开发
According to the data of oil testing in exploration wells and development dynamics of the peripheral low-ultra low permeable oil fields in Daqing, and using the basic theoretical analysis of ratio formula this paper discusses the relation between the production and productivity of oil testing stage in exploration wells and stable production stage of development and compares the effect of hysteresis waterflooding and simultaneous waterflooding development. The conclusion is: a) There is a discrete relation between the production of oil testing in exploration wells and stable production in development and a good correlativity of productivity relation. b) The productivity ratio of stable production in development and oil testing in exploration wells and the production ratio of stable production in development and early stage in development of simultaneous waterflooding development.
