摘要
针对低压油气藏的特点,介绍了国内外开发低压油气藏的一些技术现状,包括钻、完井地层保护技术,开发井网调整技术,注水(气)增压开发技术,酸化压裂等油层改造增产措施。国内外低压油气藏开发实践表明:低压油气藏开发前期,必须在钻、完井过程中进行有效的地层保护;提前注水或注气可以有效提高地层能量,改善开发效果;通过压裂提高地层导流能力可以有效提高采收率;采油工艺的改进可以提高低压油气藏的采收率。
According to the characteristics of low pressure hydrocarbon reservoirs,the technologies about low pressure hydrocarbon reservoir development at home and abroad are introduced in this paper.These technologies include the technology of reservoir protection during drilling and completion,the adjustment of producer pattern,water or gas flooding to increase reservoir pressure and acidification & fracturing.The practice of low pressure hydrocarbon reservoir development indicates that the effective reservoir protection is necessary during drilling and completion in the early stage of development of low pressure hydrocarbon reservoir,the development effectiveness can be improved by earlier water or gas flooding to increase reservoir pressure,the oil & gas recovery can be effectively increased with fracturing & acidification to increase transporting capability of reservoir,the adaptation of production technology can be used to increase oil & gas recovery of low pressure hydrocarbon reservoir.
