Title: STUDY ON IN-HOUSE EXPERIMENTS OF EOR BY NATURE GAS HUFF AND PUFF IN SMALL FAULT BLOCK CELL OIL RESERVOIR
Abstract: According to he high remaining recoverable reserves,low formation energy,strong isolatisim of well A17-b region in a small fault block oil reservoir offshore,cannot complete development state of injection-production pattern development.using the reinjection of the natural gas and carring out the huff and puff technology measure of natural gas injection per well,it is one of the most feasible methods to enhance oil recovery.Aiming at the geological and development characteristics of the reservoir in WellA17-b area,based on the phase state analysis of the formation fluids,by the swelling experiment of nature gas and reservoir fluids to determine the drive mechanism of nature gas huff and puff,by the drive experiment with long cores of natuer gas huff and puff to illustrate natural gas huff and puff injection can enhance oil recovery well after depletion,of which the result of core test with 30 degrees is better than the others.
