水平井开发底水稠油油藏氮气泡沫和冻胶控水三维物理模拟试验
Experimental study on water control and oil recovery in bottom water driving reservoirs using plugging agents
摘要
Abstract
For using horizontal wells in a heavy oil reservoir with bottom water, the bottom water breakthrough can pose a dif-ficult problem for oil production. In this study, laboratory experiments were conducted using a three dimensional physical model to simulate oil production driven by bottom water with horizontal wells. During the experiments, when the bottom water started breakthrough, plugging agents were injected through the horizontal well. The performances of N2 foam and gels were tested for water control. A similar injection scheme was followed for the plugging agents, in which three slugs with a volume of 0. 1 VP per slug were injected. The experimental results demonstrate that, after the treatments using N2 foam and the bloc-king gel in the early stage of water breakthrough, the water cut can be decreased by 48% and 24%, respectively, while the corresponding oil recovery increased by 27% and 51% for each plugging agent.关键词
