Description

Известны воздухоструйные насосы с насадками, присоедин емыми к концу подъемной колонны труб. Такие насадки креп тс  к трубам перед спуском их в скважину.Air jet pumps with nozzles connected to the end of the lifting pipe string are known. Such nozzles are attached to the pipes before they are lowered into the well.

Одним из недостатков этнх насосов  вл етс  то. что в процессе работы насадки разъедаютс  жидкостью с песком и дл  замены их новыми приходитс  поднимать всю колонну труб из скважины.One of the drawbacks of ethn pumps is. that, during operation, the nozzles are corroded with sand and, in order to replace them with new ones, it is necessary to lift the entire string of pipes from the well.

В предлагаемом насосе этот недостаток устранен тем, что насадка насоса бросаетс  в трубы и силой инерции и собственным весом самоустанавливаетс  в седле, укрепленном на конце подъемной колонны труб.In the proposed pump, this disadvantage is eliminated by the fact that the pump nozzle is thrown into the pipes, and the inertia force and self-weight is self-adjusting in the saddle attached to the end of the lifting pipe string.

Подъем насадки из скважины производитс  путем переключени  нагнетани  воздуха из центральной трубы в кольцевое пространство, вследсгвие чего клапан, закрыва сь, создает сопротивление струе воздуха , поднимающей насадку к устью скважины.Lifting the nozzle from the well is done by switching the air injection from the central tube to the annular space, as a result of which the valve, closing, creates resistance to the air jet lifting the nozzle to the wellhead.

На чертеже изображена предлагаема  насадка, состо ща  из сопла /, диффузора 2, свабба 3 и уплотн ющих манжет 4.The drawing shows the proposed nozzle consisting of a nozzle /, a diffuser 2, a swabba 3 and a sealing lip 4.

Пред мет изобретени Present Invention

Воздухоструйный насос дл  подъема жидкостей из скважин, состо щий из сопла и диффузора, отличающийс  тем, что он снабжен сваббом и уплотн ющими манжетами, позвол ющими спускать его в скважину и извлекать на поверхность путем сбрасывани  н выдавливани  вверх потоком воздуха, прокачиваемого дл  этой цели в обратном направлении, причем уход воздуха в скважину предотвращаетс  наличием под седлом насоса обратного клапана.An air jet pump for lifting liquids from wells, consisting of a nozzle and a diffuser, characterized in that it is equipped with a swabb and sealing cuffs that allow it to be lowered into the well and removed to the surface by shedding and squeezing upward a stream of air pumped for this purpose the opposite direction, with the air leaving the well prevented by the presence of a check valve under the pump saddle.
