甘谷驿油田属于典型的低孔、超低渗、低产能岩性油藏,在长期注水开发过程中,出现了部分油水井水窜现象,导致含水率较高,采油速率降低,以及注水困难等问题。为解决上述存在的问题,选择唐114井区8个注水井组作为试验区进行了空气泡沫综合调驱技术研究并在矿场进行了试验,试验结果表明空气泡沫综合调驱技术可有效地封堵油水井之间的高渗通道,见效井在不同程度上有增液、降水、增油效果。
Ganguyi Oilfield is a typical low-porosity, ultra-low permeability and low-productivity lithologic reservoir. During the long-term waterflood development, some water-channeling phenomena have occurred in oil and water wells, leading to higher water cut, lower oil recovery rate and difficulties in water injection problem. In order to solve the above existing problems, eight well injection well groups in Tang 114 well area were selected as the experimental area to conduct a comprehensive research on air foam comprehensive control technology and test in the mine. The experimental results show that the comprehensive control technology of air foam can effectively seal Plugging oil wells between the high permeability channels, effective wells in varying degrees, liquid, precipitation, increased oil effect.
