Abstract: Oil well is a basic unit of oilfield. To maintain well production above the break-even point is important for well production management. One of the targets of reservoir management is to increase benefit production through producing well management. Managers in the oilfield should fully master and utilize the variation of break-even point to adjust production deployment and maximize benefit. This paper used the break-even principle of economics, conducted economic benefit analysis about oil wells by taking a block in Zhongyuan Oilfield as an example, presented the single-well production limit of different dimensions of management such as the complete cost, the producing cost, and the operating cost, classified the benefit of single well, put forward corresponding measures, and increased economic production of reservoir, providing basis for the producing decisions made about reservoir management.

Key words: break-even point, production limit, economic benefit, oil well

摘要： 油井作为油田的基本单位,保持油井产量在盈亏平衡点以上生产,是油井生产管理中的重要内容。油藏经营管理目的之一就是通过对生产井的管理,提高效益产量。油田经营者需要充分掌握和利用盈亏平衡点的变化来调整生产部署,以实现效益的最大化。文章采用经济学盈亏平衡原理,以中原油田某区块为例,对油井进行了经济效益分析,分别给出了在完全成本、生产成本和操作成本等不同管理层面下的单井产量界限,并对单井进行了效益分类,有针对性地提出措施,提高了油藏经济产量,为油藏经营管理提供了生产决策依据。
