截至7月初,河南油田采油二厂古城油矿在泌浅10区首创氮气辅助面积注汽技术获得成功,累计增油3236吨。泌浅10区是1987年投产的热采开发区块,具有“浅、薄、稠、松、散、小”特点。经过26年的开发,已进入高含水开发后期,剩余油分布日趋复杂、分散,“疾患”越来越多。针对这种情况,古城油矿技术人员潜心钻研,大胆创新,将氮气辅助面积注汽技术应用于汽窜井区。
As of the beginning of July, the ancient city of Henan Oilfield Oil Production Plant Oilfield in the shallow 10 Paixiang first nitrogen assisted area injection steaming technology has been successful, a total of 3236 tons of oil. Pale shallow 10 area is put into operation in 1987 thermal development zone, with “light, thin, thick, loose, loose, small” features. After 26 years of development, it has entered the later stage of high water-cut development. The distribution of remaining oil is becoming more and more complicated and dispersed, and more and more diseases are emerging. In response to this situation, Gucheng oil mine technicians devoted themselves to research, bold innovation, the nitrogen-assisted area injection steam technology used in the steam blow well area.
