Abstract

Taking the shallow heavy oil reservoir of Shawan group in 510 block at Chepaizi area of Xinjiang oilfield as the object of the research, mechanism of CO2 assistant cyclic steam stimulation was analyzed a by method of PVT physical properties at high pressure. Against the problems of steam overlap, steam channeling and sand producing during development, the technology was applied at this block. Practical application results show that the average oil production increment is 206 tones and the water cut decrement is 23 percentage for treated well. Currently the accumulative oil increment is up to 6 792 tones and get profit of 15.64 million yuan. Therefore the technology of CO2 assistant cyclic steam stimulation can obviously enhance development effect and have great practical guiding significance for similar oil reservoir block.
