摘要
Abstract
We carry out oil displacement experiments in three blocks of Daqing oilfield to explore the effective development technology for Fuyang reservoir with low permeability and fracture underdevelopment.Based on the present injection profile logging technology and combined with the characteristics of the CO2 flooding,we improve logging techniques,optimize log technologies and establish better log interpretation methods.The CO2 injection profile logging methods,which are five-parameter injection profile logging technology and pulse neutron oxygen activation logging technology,are applied in 38 wells.Log datum statistical analyse shows that temperature curve of five parameter injection profile logging technology is obvious and can qualitatively indicate injection layers combining with temperature inflection points.Pulse neutron oxygen activation logging technology can quantitatively calculate injection sizes of every layer,but the peak more disperses in low flow,the characteristics of peak location are not fully in line with normal distribution.Peak has slight trailing due to instrument spacing restriction.Minimum measure value of oxygen activation logging tool is 10 m3/d.关键词
