| After water drive and polymer drive,Natural gas drive is another important drive technology.Foreign gas displacement technology developed rapidly in recent years,and with an expanding trend of the implementation of the improved recovery.Because of our country's main oil-producing conditions such as natural gas air tight and related equipment,making the technology in our country had a slow start.But along with the related conditions gradually improve and further improve the gas injection technology research,gas flooding also has made great progress,at present our country has multiple oilfield gas displacement field.This paper reviewed the current situation and development trend of natural gas development,analyzes the basic overview and development status of Dalinghe reservoir in block Jin 31 at present,natural gas in the laboratory to determine the minimum miscibility pressure,the oil reservoir and enhance oil recovery potential and reservoir structure analysis,carry out natural gas injection study on Applicability of flooding.The displacement efficiency of different development models was determined by physical simulation test,and the optimal displacement method was determined.Based on the simulation of 3D reservoir geological modeling and numerical flooding scheme and optimization,design of Dalinghe reservoir in block Jin 31 natural gas. |
