通过对河南油田古城BQ10区块超稠油掺稀油降粘集输、掺热水降粘集输等室内和现场试验分析,提出和实施了BQ10区块污水回掺低耗节能降粘集输工艺,并阐述分析了污水回掺降粘机理,经过3年的生产试验表明,古城BQ10区块单元内部污水回掺降粘集输工艺,既满足了超稠油的生产需要,又达到了节能降耗的目的。 Through the laboratory and field experiments on the viscous oil gathering and transportation of ultra-heavy oil in BQ10 block in the ancient city of Henan Oilfield, the low-energy and energy-saving viscous gathering and transportation of BQ10 block was put forward and implemented After three years of production tests, it shows that the technology of back-mixing and desizing for sewage in BQ10 block unit in ancient city not only meets the production needs of super-heavy oil but also achieves energy saving The purpose of reducing consumption.
