The pumping unit commonly used in an oil field is equipped with an elastic tensioning device for oil field pumping units with a weight of 100 kilos and a volume similar to that of a desktop computer. The pumping efficiency is increased by 6% to 7%. It also reduces pumping belt replacement frequency and maintenance costs.
In the trial production site of the No. 1 plant in Jiangsu Oilfield, the reporter learned that a small device that was developed by the East Suspension Co., Ltd., which was added to the pumping unit, solved the "big problems" in the oil field production process.
Willing to invest, small village enterprises jumped into "leader"
It is well known in the industry that oilfield development in the later stages of development will have high energy consumption and high costs. In the production process of oil extraction, the pumping unit belt is a vulnerable part, and replacement will not only take time and effort, but will also affect production. According to surveys, when the temperature in the northeastern winter is below -30°C, the production of oil wells that have stopped production due to belt slippage (displacement) is about 5,000, and the direct economic loss exceeds 100 million yuan. The oil wells that had not been shut down were also slippery (displaced) due to loose belts, and the oil rate in general appeared to drop significantly, and the annual loss was estimated to exceed 200 million yuan. Even if the temperature is normal, the belt is loose and slippery (discarded) in the event of rain and snow, and the efficiency is also falling rapidly, resulting in an annual comprehensive loss of more than 300 million yuan. At the same time, in the crude oil production cost of oil fields, the pumping and electromechanical expenses account for about 30%. Therefore, it is necessary to carry out technological transformation of energy saving and efficiency improvement for pumping units.
"In order to improve the efficiency of China's oil extraction and reduce the cost of exploitation, we have given full play to the company's technological advantages accumulated over the years and have invested more than 10 million yuan to focus R&D efforts on accelerating the research and development of oil field pumping unit belt transmission elastic tensioners." Mr. Tie Deshun, chairman of the company, said. As the only national high-tech enterprise in the elastic device industry, the East Hanger has been devoted to the research and development of elastic components since its establishment in 1987. It has established the Jiangsu Provincial Research Center for Elastic Components and Devices Engineering Technology, and at the same time, is deeply involved with Tsinghua University. The cooperation between production, education and research is carried out, and new products are developed around the needs of the market. So far, it has undertaken 15 provincial-level scientific research projects, including 7 at the national level; it has 41 patents, including 24 invention patents, and 5 provincial and ministerial-level scientific and technological progress awards.
“We have always been willing to invest in the introduction of talent and scientific research and development, and established a strong scientific research and development team.†Weishun Shun told reporters that although the East Hangar started from an ordinary spring production company in the village, but After 30 years of unremitting innovation, it has now developed into an "innovative enterprise" supporting major national key projects and a "leader" in the city's industrial upgrading. The new generation of energy-saving and efficiency-enhancing products applied to the oilfield oil recovery machine developed by the company is another work after the company's innovation of the railway electrification compensation device to overcome the high-speed rail world problems.
Simple and efficient, small devices help oilfields improve
“This is a new structure of tensioning device using high-performance planar scroll springs as elastic elements. This purely mechanical and high-performance device ensures the change of the elasticity of the belt or the chain. It is a simple structure, high performance and longevity. The long and convenient device that can be installed quickly and without maintenance, said Wu Liqun, chief engineer of the East Hanging Crane, told reporters.
Wu Liqun also introduced that its key technology and independent innovation lies in the use of one or more sets of planar scroll spring combinations to meet the requirements of different oil extraction machine models and different working conditions on the belt tension; using die-cast aluminum alloy rotary pressure Wheels, reduce the wear of the roller on the belt; with tensioning adjustment device, the tensioning force can be set and adjusted according to the actual conditions of use to ensure that the belt tensioning is in the most efficient working state, so as to achieve the reduction of the unit energy of the oil recovery machine. The high-performance plane scroll spring used in the key parts of the elastic tensioning device with a (chain) transmission is a special requirement for a flat scroll spring with low consumption and long service life.
After the successful development of oil field pumping unit belt transmission elastic tensioner, it has passed several technical tests in Shengli Oilfield and Jiangsu Oilfield, and has rapidly demonstrated in Jiangsu Oilfield. From the use of the situation, the oil field pumping unit belt transmission elastic tensioning device is very effective, reaching about 6%.
“Although this figure does not seem to be single, but the actual calculation of the entire crude oil exploitation, the amount of promotion is enormous.†Tie Deshun quickly calculated such an account: “According to the past two years from Shengli Oilfield and Jiangsu Oilfield. According to the report provided by the user, each pumping unit can produce 250 to 300 kg of crude oil per day if the power consumption is basically unchanged, if the 200,000 pumping units in the country are all adopting this type of belt drive and elastic tensioning. The installation can produce 15 to 18 million tons of crude oil per year, which is equivalent to the annual production of 10 to 12 Jiangsu oil fields."
With the innovative concept and development strength, the market of Oriental hangers is getting wider and wider. “Our core technologies have been successfully applied for patents in China and in the United States, Japan, Germany, France, Canada, India and the European Union. From this year, we will accelerate the demonstration and promotion of oil fields at home and abroad, and further increase the efficiency of China’s oil production. "Tie Deshun said.
