Island oilfield thermal recovery throughput technology , the thin layer of unconsolidated sandstone heavy oil reservoir into industrial development , but after high round of high water cut depth development phase , the thermal recovery of old wells for 5 to 6 cycles , water invasion effects increasing , stable foundation is weak , economic deterioration . To explore the effective yield to succeed in the the island heavy oil throughput development , island since the 2008 oil field to carry out the solitary gas 9 turn steam flooding feasibility study and test . 9 for solitary gas complex geological conditions , to carry out the fine reservoir description , in-depth study of the unit micro - structure , reservoir distribution law of reservoir heterogeneity , distribution interlayer , the remaining oil ; steam flooding mechanism , results of numerical simulation and optimization is proposed to meet the screening criteria for steam flooding ; perforating technology supporting steam flooding , with production with injection technology , injection and adjustment techniques , dynamic monitoring carried out a comprehensive study , formed island oilfield steam drive supporting technology . 9 solitary gas steam flooding technology with good results , the moisture content decreased, production rose greatly improved oil recovery .
