Exploitation of oil sucker-rod pumps is one of the main mechanized methods of oil-mining. All machines are equipped with powerful electric engines, control stations, transformer substations, and overhead power lines. But we can do without this equipment, if in order to drive a pumping machine we use gas engine (GE) powered by associated petroleum gas (APG), obtained in the same well. It solves several problems at the same time. Firstly, associated petroleum gas is utilized. APG is a mixture of hydrocarbon gas dissolved in oil and it's produced in the result of extraction and distillation. (20-500 m3 of gas per ton). In recent years, the public has paid close attention to the problem of utilization of associated gas, as well as increased penalties for inefficient use of valuable raw materials. From 60 billion m3 of associated gas, produced in the country each year, only half is utilized. The rest is simply flared, leading to half a million tons per year of harmful emissions into the atmosphere and tens of billions dollars of lost profit. Secondly, at the same time it saves energy, because energy costs play a significant part in the cost of oil. Also it ensures uninterrupted oil production in small fields of remote single wells, where it's very expensive to form air lines. On some wells of "RITEK" the volume of associated gas is large enough. This makes the use of internal combustion engine for driving gears of pumping machines more cost-effective than the use of conventional electric drives.
