Description
Technical field
The utility model relates to a kind of oil exploration equipment, particularly a kind of broadband type ultra-long-stroke twin-well oil-pumping machine.
Background technology
At present, mainly there is following weak point in China's oil-field oil pumper:
1. pumping efficiency is lower, and energy consumption is big.According to statistics: domestic oil pumper operational efficiency is generally on the low side, and average efficiency 25.96% abroad is 30.05%, year power consumption 57.6 hundred million degree.Suppose these energy consumptions all by thermal power generation, be equivalent to consume 2,400,000,000 kilograms of coals, the pollution of environment is well imagined.
2. Cong Jing oil pumping popularity rate is low, and the pumping-unit motor utilization rate is also low simultaneously.Domestic in recent years old filed has been beaten a lot of infill wells for improving output, makes the oil well distance reduce to more than 10 meter, bores cluster well 800-1000 mouth every year, and cluster well accumulative total reaches 6000 mouthfuls at present, but domestic cluster well still mainly adopts the individual well oil pumper.Individual well oil pumping motor utilization rate is extremely low, and waste of energy is bigger.
3. the oil pumper stroke is shorter, no beam pumping unit slower development.The stroke of oil pumper has not only determined the tar productivity of oil pumper, and has determined the scope of application of oil pumper, particularly deep-well and heavy oil wells.Along with the rising year by year of China's oil field oil production, the quantity of taking out well, heavy oil wells and many gas wells deeply also constantly increases.For example, China's viscous crude stock number rich, nearly 20,000,000,000 t of stock number.By the end of the year 2002, accumulative total is verified oil in place 18.4 hundred million t.Thereby also be an importance of China's oil exploitation to the exploitation of viscous crude.These objective condition factors require us must develop long stroke pumping unit.Yet China at present employed long stroke pumping unit in each oil field (stroke is above 5 meters) is main with beam pumping unit still, when the stroke of this oil pumper extends, and also at double the increase of its quality.Like CYJQ16-6-105B oil pumper, its quality has surpassed 60t.
