It is understood that the Liaohe Oilfield began in 2004, special oil company Du 84 block SAGD technology test, achieved significant results, continue to break. However, the important components of its supporting system, such as oil pump, polished rod sealer and detachable lifting device, still need to be imported from abroad. Import pump price is very expensive, raising the cost of implementation, SAGD technology, after the formal maturity, will also bring high cost to the trouble of production.
In order to solve the above problems as soon as possible, Liaohe Oilfield will independently develop SAGD pump lifting system technology and related products to the task of drilling technology research institute. Drilling Technology Research Institute researchers conducted a systematic study to tackle the problem, adjust the parameters, the preferred material, designed a common type pump and a large pumping pump two options, the use of self-developed special manufacturing process successfully developed two sets of new Pump products.
Both sets of pumping pumps achieved good results through preliminary tests on site SAGD wells. At present, the technology has been conducted in horizontal wells in 9 wells in field tests, of which 4 wells have been working for more than 4 months, showing excellent performance, basically the same with foreign machining and processing accuracy.
According to reports, once the technology and related products achieved full success, large-scale application, will save a lot of Liaohe Oilfield production costs.
SAGD big pump lifting research has made significant progress
Major technological research in Liaohe Oilfield SAGD technology has made major achievements in research, the technology of ancillary technologies - lifting system technology has been successful, serialization of technology products have entered the stage of implementation of the application field, the effect is good, is expected to replace foreign related products , A strong guarantee for the implementation of SAGD technology. This marks the Liaohe Oilfield SAGD lifting system technology applications, will use its own research and development of technology and products.
