摘要:
针对江苏低渗油藏开发过程中的问题,开展了基于核磁共振二维谱技术的水驱油实验研究,对比分析了不同驱替阶段的油水变化规律。结果表明:在水驱初期,连片状剩余油占主导地位;随着水驱的进行,连片状剩余油体积比例不断降低,而其他三种剩余油比例不断增加,同时,连片状剩余油体积绝对量不断降低;水驱后期,连片状剩余油不再处于主导地位,但其体积绝对量与网络状、孤岛状体积绝对量相当,依旧具有较大的开发潜力。
Abstract:
Aiming at the problems in the development of low permeability reservoirs in Jiangsu Oilfield,an experimental study of water-driven oil based on nuclear magnetic resonance (NMR) two-dimensional spectroscopy was carried out to compare and analyze the oil-water change laws during different displacement stages. The results show that in the early stage of water flooding,continuous residual oil is dominant. With the progress of water flooding,the volume proportion of continuous residual oil decreases continuously,while the proportion of the other three types of residual oil increases continuously. At the same time,the absolute volume of continuous residual oil decreases continuously. In the later stage of water flooding,the continuous residual oil is no longer in the dominant position,but its absolute volume is comparable to that of the network and isolated island,which still has large development potential.
