Market forecast: This product not only achieves 50% energy saving and 50% pump efficiency during oil recovery, but also reduces the one-off cost of oil recovery equipment and solves the problems of shaft oil production and shallow sea oil recovery. According to the statistics of PetroChina, the average number of new drilling wells is 10,000 per year in recent years. The maintenance of old wells needs to be replaced by 5,000 and the annual total domestic demand is 15,000. In the international market, the number of newly-produced oil wells exceeds 100,000 each year. At present, the international oil price soars. As oil companies reduce the cost of oil production and increase oil production, upgrading of equipment is imperative. From the above data we can see that the market demand for the product will be very huge. Technical status and relying on units: NC reciprocating submersible pump used in the oil field. Oil collection principle is the original kowtow machine from the ground to absorb oil, converted from the underground reservoir oil will be lifted directly to the ground mode, breaking the traditional oil recovery. In addition to energy conservation and efficiency, there are the following advantages: First, to solve the original shaft oil production problems; Second, according to the geological conditions of the oil can be adjusted online at any time parameters; third is to improve the geological oil content recovery rate; Fourth, reduce the original equipment maintenance costs; Fifth, environmental protection, to solve the river, river, lake, shore oil wells pollution problems. The project relies on Shenyang Luhai Oilfield Equipment Manufacturing Co., Ltd., the current product has entered the practical application stage. Daqing Oilfield, Shengli Oilfield and Liaohe Oilfield have undergone more than 400 downhole operations. After more than 50 wells have been tested, the data show good results and all the data indicators are in line with the requirements. The key technology of this project has been simultaneously applied for the invention patent and utility model patent of China on September 17, 2004. At the same time declare an international patent, international patent PCT organization in September 2005 to check the new project, accepted, the actual application.
