The Steam Flood Field Test After Hree-component Compounding Displacement Of North 2 East Small Well Spacing

Pilot tracey of the minesites made us known that the output coefficient of complex displacement technology may attain about seventy per hundred, yet it is about thirty per hundred of oil remaining. It is a important topic that how about unearth the remaining reserves. Thermal recovery may improve the fluidity of the crude oil, moreover, it have the effect of overlapping driving. It is a considerable replacement technique that effectively displaced the remaining oil in the peak of the thick oil layer. Hence, North 2 East small well spacing south well group launched steam flooding field test after three-component compounding displacement and analysed North 2 East small well spacing oil layer inject gas adaptiveness. It provided the foundation for launching steam drive in the future. At the same time, evaluated the effect of the steam drive, researched the intensity of the breath, the scope of added oil, the change of the after the steam drive and so on. After three-component compounding displacement, as to North 2 East and proximate analogous block, these outcome offered foundation about the theory and the actuality for the technique of implementing gas drive recovery. It provided the gurrantee for acquired predetermined technique and economical target to steam drive.
