China's high temperature electric submersible pump oil production technology to break the international monopoly
By August 3, the first domestic submersible electric pump operated smoothly for 20 days at a high temperature of 200 ℃ in SAGD well and produced 40 tons of crude oil per day, 10 tons more than before the measure, marking an international monopoly of the technology. "Declared an end.
"The core technology research and development took 6 years." Zhang Shoujun, chief engineer of the Liaohe Oilfield Shuguang Oil Production Plant, which led the project, said in an interview that the domestic high temperature submersible electric pump technology has long been imported due to its long-term resistance to hot materials. In order to meet the industrialization needs of SAGD high-temperature steam stimulation oil production technology, in the 6 years, the technicians of Liaohe Oilfield Shuguang Oil Production Plant cooperated with domestic institutions of higher learning to innovate high temperature resistant motors, metal capsule protectors, high temperature centrifugal pumps, high temperature and high pressure sealed boxes , High temperature resistant cables and other complete sets of technologies. The overall supporting technologies such as synchronous bundled temperature and pressure monitoring system, multi-channel crossing structure high temperature electric pump wellhead, pipe supporting tools and ground simulation test equipment have been improved and perfected.
"Currently SAGD horizontal well of high temperature submersible pump oil production temperature capability up to 250 ℃, compared to the existing domestic high temperature pump, temperature capability increased by 70 ℃, compared to the current import of foreign high-temperature pump, temperature Ability to raise 32 ℃. "Dawn oil plant technical experts, project leader Ron Yong said.
In order to ensure the success of high-temperature submersible pump test, the Institute of Technology and manufacturers to create a special large-scale ground test device, the use of 55-degree tilt display, 250 ℃ HTF as a medium to simulate the actual underground environment for ground testing .
July 10, the technology in Nissan up to 30 tons of Du 84 Hall Ping K58-1 well into the scene and made a successful test, the first 15 wells open production. The current motor frequency of 43 hertz, the output current of 18.8 amps, downhole temperature of 198 ℃, 290 tons of oil well Nissan, Nissan 40 tons.
"From the operational point of view, the technology fully meets the program design requirements." Ron Yong said.
In talking about the advantages of high temperature electric submersible pump, the project leader said that the process rodless mechanical transmission, a large displacement range, high head, effectively solved the rod pumping pumping system affected by the deviation , Limited displacement bottlenecks, in order to further expand the SAGD well production scale and carry capacity, provided technical support.
