摘要:
克拉玛依油田九区J230井区上侏罗统齐古组稠油油藏储集层非均质性强、油层薄,天然能量低。随着蒸汽吞吐油井生产轮次增高,油田开采步入中—后期,储集层含油饱和度大幅度降低,剩余油分布复杂,地层压力低,高含水井逐年增多,开发难度增大,油田采油速度和经济效益大幅度下降。1995年开始开展了注氮气辅助吞吐的矿场试验,应用实践表明:注氮气后可以有效补充地层能量,延长吞吐生产时间,提高稠油热采开发效果。然而,多轮次注氮气辅助吞吐开采后,注气井汽窜矛盾突出,为此开展了氮气泡沫辅助吞吐及调驱试验研究。研究结果表明,高温泡沫剂发泡性和稳定性好,用在非均质性强的普通稠油油藏,可显著提高采收率。
Abstract:
The heavy oil reservoir of the Upper Jurassic Qigu formation in Well block J-230 of District No.9, Karamay oilfield is characterized by serious heterogeneity, thin oil layers and low natural energy. As the oilfield development is at the mid-late stage, the oil saturation of the reservoir significantly decreases, the residual oil distribution is complex, the formation pressure is low and there are more and more high water-cut wells, which results in the difficulties of development and sharp decrease of oil production rate and economic benefit. A field test of nitrogen assisted steam huff and puff technology was carried out in 1995 and the results showed that nitrogen injection could replenish formation energy effectively, elongate huff-puff time and improve the development effect of thermal heavy oil recovery. Whereas, because steam channeling is serious in injectors after multi cycles of nitrogen assisted steam injection, experimental studies are conducted on nitrogen foam assisted steam huff and puff and its profile control and flooding. The results show that high-temperature foaming agents with good foaming ability and stability can be used for common heavy oil reservoirs with strong heterogeneity, with which the oil recovery factor can be significantly improved
