Changchun Ridge Countermeasures Research Oilfield Development Way Exploration And Production

Oilfield in Jilin changchun ridge SongYuanShi， tectonic location is located in thesoutheast uplift area in southern songliao basin in changchun LingBei slant fuyu Ⅱ in itsconstruction， the main purpose of the development of fuyu oil layer. The crude oil viscosity，liquidity is poor，for the low temperature，low pressure，shallow heavy oil reservoirs，theconventional way to development， therefore need to choose a way to adapt to thedevelopment of such reservoirs.By conducting a variety of field test， analysis and evaluation the adaptability of thesearch for a suitable mining method， and through stabilize technology policy research，control water cut increase rate， slow down the natural decline， stabilize implementation，form the low temperature low pressure reservoir development mode， for changchun ridgearea of more than30003000tons not producing reserves to provide development basis.In this paper mainly summarizes the several hot test stope， comprehensive evaluation ofthe effect benefit， eventually because the conventional thermal recovery of large energyconsumption，low single-well production，poor development effect and economic benefit islow， is not suitable for the oilfield development. For long and109block reservoir geologicalcharacteristics， on the basis of detailed research， through the indoor experiment simulationand calculation， optimize and design the development plan of the district， on the basis ofthe comprehensive evaluation concluded that hot water flooding plan as a whole can improvethe long109block formation pressure， temperature， natural decline rate slowed sharplyoilfield， improve oil recovery， can serve as a development technology for low temperaturelow pressure of reservoir; Also puts forward the direction of next step optimization potentialand well pattern adjustment suggestion.109block of hot-water flooding technology research， economic and effectivedevelopment of Changchun hill oilfield is of great significance.
