可控不压井作业技术,是在带压作业技术的基础上,经过简化、改进和完善,形成的适合于小修作业的作业装备和作业技术。在作业时,用环形密封器密封抽油杆和油管环空,油管内流体通过管线进入地面储液罐,实现起下抽油杆作业。本文针对辽河油田欧利坨地区实施不压井作业提高欧利坨油田开发效果。 Controllable non-pressure well operation technology is based on the pressure with the job technology, through simplification, improvement and improvement, formed for the minor repair operations equipment and operating techniques. During operation, the sucker rod and tubing annulus are sealed with a ring sealer, and the fluid in the tubing passes through the pipeline into the ground storage tank to achieve the operation of sucker rod. This paper aims to improve the development effect of Oly Tuo oilfield by performing no-well operation in Ouli Tuo region of Liaohe Oilfield.
