Abstract

A beam-type pumpjack consists of: a support, a body, a crank, a walking beam and a head, a suspension mechanism with a cable, a polished rod with a rod string, a wellhead seal, production tubing, and a geared motor, and is characterized in that fastened along the walking beam is the rod of a rod string hydraulic cylinder, the ends of which are fastened, via a cable and a pulley mounted on the upper part of the head, to the rod string suspension; the production tubing is mounted with the aid of a special attachment to the end of the rods of hydraulic cylinders fastened to a casing string; and the annuli of the rod string hydraulic cylinder and the production tubing hydraulic cylinders are connected to pipes as communicating vessels (as explained in physics). The hydraulic cylinders move the rod string and the tubing string by receiving force from an individual motor pump via a valve mechanism, the weight of the respective strings being counterbalanced by virtue of the diameters of the pistons of the hydraulic cylinders. Via the valve mechanism, which is controlled by a tracing follower, an oil-circulating power pump supplies oil, according to a set programme, to the head of the pistons of the rod string hydraulic cylinder and the tubing string hydraulic cylinders in turn. When the walking beam begins to move upwards, the suspension point of the rod string moves upwards according to a set programme, and, by virtue of the communicating cylinders, the tubing string moves downwards; at the same time, the stroke of the plunger increases due to the relative movement on the walking beam and the movement of the tubing string in the opposite direction. The set programme of the suspension point of the rod string provides attenuation of hydraulic shocks on the apparatus, thus increasing the service life of the apparatus.

Description

Балансирный станок - качалка комбинированный с гидроприводом системой типа АГН Balancing machine - rocking chair combined with a hydraulic drive system of the AGN type
Полезная модель относится к области добычи нефти штанговыми глубинными насосами. Известен станок-качалка (Ns 682668, авторы Киселев Н.Г. и др. опубл.30.08.79, бюл. Ns32), установленный на фундаменте и содержащий раму со стрелой, стойку, балансир, канатную подвеску, головку балансира с роликовым узлом для крепления канатной подвески и дополнительную стойку, установленную на фундаменте, связанную со стрелой и имеющую ось, на которой установлен шкив. Данный станок-качалка может применяться только в двухствольных скважинах и длина хода насоса минимальная. The utility model relates to the field of oil production by sucker rod pumps. Known rocking machine (Ns 682668, authors Kiselev N.G. et al. Publ. 30.08.79, bulletin Ns32), installed on a foundation and containing a frame with an arrow, a stand, a balancer, a rope suspension, a balancer head with a roller assembly for fastening the rope suspension and an additional stand installed on the foundation, connected to the boom and having an axle on which the pulley is installed. This pumping unit can only be used in double-barreled wells and the pump stroke length is minimal.
Близким по технической сущности к заявляемой полезной модели является штанговая глубинно-насосная установка с гидроприводом типа АГН, (см. совместные научные труды Азизов С.А., Молчанов А. Г.„Некоторые особенности штанговых глубинных насосов с гидроприводом типа АГН.„АНХ номер12, 1978т). содержащий штанговый гидроцилиндр, трубный гидроцилиндр сообщающий между собой сообщающиеся сосуды, механизм реверса и силовой мотор насос. Недостатком этой установки является не удобство при эксплуатации при подземных ремонтах скважин. Наиболее б изким техническим решением к заявляемому является полезная модель (Ne201S111865\06, 01.04.2015 опубл. бюл. RU_158764 U1 Аухадеев Р.Р. и др. ) при этом сделана попытка найти путь повышения кпд станка и уменьшение гидроудара. Close in technical essence to the claimed utility model is a sucker rod pumping unit with a hydraulic drive of the AGN type, (see joint scientific works of S.A. Azizov, A.G. Molchanov “Some features of deep-well sucker rod pumps with a hydraulic drive of the AGN type.” ANKh number 12 , 1978t). containing a rod hydraulic cylinder, a tubular hydraulic cylinder communicating with each other communicating vessels, a reverse mechanism and a power motor pump. The disadvantage of this installation is the lack of convenience in operation during underground workover of wells. The most common technical solution to the claimed is a useful model (Ne201S111865 \ 06, 01.04.2015 publ. Bul. RU_158764 U1 Aukhadeev R.R. and others), while an attempt was made to find a way to increase the efficiency of the machine and reduce the water hammer.
Но еще не был найден путь решения длинноходовой эксплуатации при гибким управлением точки подвеса штанг. But a way has not yet been found to solve long-stroke operation with flexible control of the suspension point of the rods.
Задачей полезной модели является увеличение длины хода насоса, уменьшение гидравлического удара повышение кпд станка при минимальной металлоемкости. The task of the utility model is to increase the pump stroke length, reduce water hammer, and increase the efficiency of the machine with minimal metal consumption.
Поставленная задача решается тем, что в балансирном станке-качалке (фиг 1) состоящем из опоры 1, корпуса 2, кривошипа, балансира 3 (сечение фиг.2 и 3 ) и его головки 4, механизма подвески с канатом 5, „полированного штока., колонны штанг, устьевого уплотнителя, НКТ, мотор-редуктора 6, новом является то, что вдоль балансира закрепляют шток 8 штанговый гидроцилиндр 7 конец которых закреплен через ролик 9 канат и ролика 4а, установленный на верхней части головки, с штанговой подвеской, НКТ 15, с помощью муфты 16, специальной оснастки 17 устанавливают в конце штоков 18 гидроцилиндров 20, закрепленной с помощи опор 21 к обсадной колонне 22, межтрубные пространство штанговых и трубных гидроцилиндров соединяется с трубами 23 как сообщающиеся сосуды (в физике разъяснено). Гидроцилиндры двигают колонны штанг и труб, получая через золотниковый механизм 11 (с капером 11а и следящим роликом Ив - фиг.4), движущую силу от индивидуального мотора-насоса 10, при этом их весы уравновешиваются с помощью диаметров поршней гидроцилиндров 20. Для повышения эффективной работы установки, по необходимости снабжается компенсатором 13, Установка работает следующим образом: масленый силовой насос 10 через золотникового механизма 11 управляемое с помощью копирного 11в следящего 11а механизма по определенной программе подает рабочее масло на головку поршней поочередно штангового 8 или трубного 20 гидроцилиндров. Когда балансир 3 начинает движение вверх точка подвеса 5 штанг по заданной программу перемещается вверх, в силу сообщающих цилиндров, НКТ 20, перемещаются вниз, при этом ход плунжера одновременно увеличивается за счет относительного движения на балансире 3 и движение НКТ 20 в противоположную сторону. Таким образом за счет увеличения длины хода насоса увеличивается кпд, за счет уравновешивания с помощью веса НКТ уменьшается металлоемкость и увеличивается длина хода насоса и с помощью оптимального движения точки подвеса штанг уменьшается гидроудары, что способствует увеличению надежности и долговечности установки. The problem is solved by the fact that in the balancing machine-rocking chair (Fig. 1) consisting of a support 1, a body 2, a crank, a balancer 3 (section Figures 2 and 3) and its head 4, a suspension mechanism with a rope 5, a “polished rod. , string of rods, wellhead seal, tubing, gear motor 6, new is that the rod 8 is fixed along the balance beam, the rod hydraulic cylinder 7, the end of which is fixed through the roller 9, the rope and the roller 4a, installed on the upper part of the head, with a rod suspension, tubing 15 , with the help of a coupling 16, special equipment 17 is installed at the end of the rods 18 of the hydraulic cylinders 20, fixed with the help of supports 21 to the casing 22, the annular space of the sucker rod and tubular hydraulic cylinders is connected to the pipes 23 as communicating vessels (in physics explained). The hydraulic cylinders move the columns of rods and pipes, receiving through the spool mechanism 11 (with the marque 11a and the follower roller Yves - Fig. 4), the driving force from the individual motor-pump 10, while their weights are balanced using the diameters of the pistons of the hydraulic cylinders 20. To increase the effective operation of the installation, if necessary, it is supplied with a compensator 13, The installation works as follows: an oiled power pump 10 through a slide mechanism 11 controlled by a follower 11b of the follower 11a, according to a certain program, supplies working oil to the piston head alternately of a rod 8 or pipe 20 hydraulic cylinders. When the balance bar 3 begins to move up, the suspension point 5 of the rods moves up according to a predetermined program, due to the communicating cylinders, the tubing 20, moves down, while the stroke of the plunger simultaneously increases due to the relative movement on the balance bar 3 and the movement of the tubing 20 in the opposite direction. Thus, due to an increase in the pump stroke length, efficiency increases, due to balancing with the help of the tubing weight, the metal consumption decreases and the pump stroke length increases, and with the help of the optimal movement of the suspension point of the rods, water hammer is reduced, which contributes to an increase in the reliability and durability of the installation.
Заданная программа точки подвеса штанг может обеспечиваться с помощью ЧНУ смягчению гидравлических ударов на установки и тем самым получается дополнительный эффект увеличение долговечности установки. The preset program of the suspension point of the rods can be provided with the help of the PNU to mitigate hydraulic shocks on the installation, and thus an additional effect of increasing the durability of the installation is obtained.
