摘　　要：化学驱是提高原油采收率的方式之一。为确保化学驱均衡驱替,减少药剂损失,在综合考虑合理注入速度、井组孔隙体积、合理注入强度、合理注采比、注采关系、连通状况、外部来水等关键因素的基础上,提出了化学驱合理配产配注的流程,以及井网上所有注入井合理注入量和采油井合理产液量的计算方法,强有力地支撑了化学驱油藏工程设计。Chemical flooding is one of the ways to improve oil recovery.In order to ensure the balanced displacement of chemical flooding and reduce the loss of chemical agents,based on the comprehensive consideration of the key parameters such as reasonable injection speed,well group pore volume,reasonable injection intensity,reasonable injection production ratio,injection production relationship,connectivity status,external water,etc.,the workflow of rational production and injection allocation of chemical flooding and all injection on the well network are proposed.Besides,the calculation method of reasonable injection rate and reasonable liquid production rate of production wells are also proposed,which strongly supports the engineering design of chemical flooding reservoirs.
