Abstract

After the XQ-45 block entering the multiple rounds of steam huff and puff, it is affected by faults, reservoir properties, edge water and other factors. The remaining oil distribution is complex, and steam huff and puff effect is getting worse. According to the reservoir dynamic data, this block is selected as a test block to improve the steam huff and puff development effect of nitrogen foam. The 79 wells in this block are divided into different types of heavy oil wells according to the remaining oil saturation parameters. Aiming at the high-level intervals in the oil wells with different layers, then take nitrogen foam profile control measures to adjust the suction profile, and optimize the optimal nitrogen foam injection parameters are: nitrogen foam injection volume is 0.2pv, foam concentration is 0.5%, gas liquid ratio is 2: 1, cycle steam injection volume is 100t/m. The results show that the oil production is the largest in the second round of profile control, the average daily oil production is 3.89t, and the cycle oil-gas ratio reaches 0.32. On this basis, continue to increase the profile control round, after the profile control 5 rounds, the average daily oil production is 3.18t, the average oil-gas ratio is 0.26, the cycle of cumulative oil production is 1431.23t, and the program implementation effect is getting better.
