... сваи, вворачиваемые на необходимую глубину до прочного грунта и ниже глубины его промерзания в зимний период. This work presents a novel design of an open-type chain drive for a sucker-rod pumping unit with a 3.5-m length stroke and a 35 kN load capacity. This chain drive is mounted directly above the well head, and is an optimal solution for rod-lift production of low-volume wells. For the chain drive body,...

... the key. In this article, we propose to discuss in detail the solution of the problem of import substitution in the field of operation of wells with sucked downhole pumping units with hydraulic ground drive, instead of traditional rocking machines and chain drives. Results he positive effect of the use of hydraulic drives PNHSNG 120-6-24:Increase in oil production. Reduction in the level of design failures. Reduction of equipment downtime andrepair costs. Cost optimization has been achieved in ...

... затрат связанных с ПРС составил 126,8 тыс. руб./ год, экономия электроэнергии составила в среднем 15-20% или 15,8 тыс. руб./год на один привод. History of the chain drives dates back tothe 30s of last century, when on October 2,1933 in the USSR, K.K. Riedel was patented conventional pumping unit with a long course, designed for deep oil pumps for ultra-deep wells. Its structure consisted of a wooden frame, ...
