非均质油藏CO2泡沫与CO2交替驱提高采收率研究
Experiment Research of CO2 Foam Alternating CO2 Displacement EOR Technology in Heterogeneous Reservoir
摘要
Abstract
For CO2 flooding in heterogeneous reservoir, gas channeling of CO2 is easy and premature to happen along the high permeable layers, which leads to low recovery efficiency of CO2 flooding and low - permeability reservoir is difficultly produced, optimal selection of different CO2 injection modes was developed in laboratory test. The influence of slug size, foam - gas ratio and surfactant - gas ratio on the optimal injection mode was also studied. The results show that foam-gas alternative flooding is an effective practice to tackle serious interlayer contradiction and prevent early gas break-though, leading to a high oil recovery. The best parameters for FAG are as following: slug size (0. 4 PV), foam - gas ratio (1 : 1), surfactant-gas ratio (1:1)关键词
