摘　　要：为了有效动用大庆外围"三低油藏",提高该类储层的开发效果,在大庆肇源油田开展了矩形井网的开发试验。在经济界限内确定合理井网的基础上,结合肇源油田储层物性的特点,优化实施了矩形井网中油水井整体压裂规模,优选应用了一系列压裂配套工艺及油层保护技术,使油田的产能指标和吸水指标达到了方案预测要求。开发效果表明,矩形井网开发技术能够适合大庆外围低渗透油田的开发需要。In order to develop effectively the peripheral reservoirs with low permeability, porosity and productivity in Daqing Oilfieid and increase the development effect of this kind of reservoir, the rectangular well pattern test is carried out in Zhaoyuan Oilfield. Based on the determined reasonable well density and combined with the reservoir physical properties, this paper optimizes the integral fracturing scale of injector and producer in rectangular well pattern, selects and applies a series of matched fracturing technologies and reservoir protection technologies, making the production index and water absorbing index reach the goal of plan forecast. The practices prove that the development technology by rectangular well pattern is suitable for the development of the peripheral reservoir with low permeability in Daqing Oilfield.
