长庆油田油藏效益分类及开发对策

在长庆油田油藏类型不断增多、国际原油价格低位徘徊的双项作用下,厘清长庆油田不同类型油藏效益类别和识别不同类型油藏在不同油价下原油产量界限,成为油田公司生产经营决策的迫切需求。按照效益评价与油藏研究、动态开发情况、油井生产故障及综合治理相结合的分析方法,构建不同类型油藏的成本、开发指标与效益的关系,进行低效井影响因素分析,为油藏的效益开发提供参考。

Reservoir Benefit Classification and Development Countermeasures for Changqing Oilfield

Influenced by the increasing reservoir types in Changqing oilfield and the low international crude oil price, clarifying the benefit categories of reservoirs and identifying the oil production limits of different types of reservoirs under different oil prices are urgent for Changqing Oilfield Company to make production and operation decisions. By combining the benefit evaluation with reservoir research, dynamic development, well production failure and comprehensive treatment, the relationship between cost or development index and benefits for different types of reservoirs was established, and the influencing factors of low-benefit wells were analyzed, providing a reference for cost-effective development of reservoirs.
