Numerical simulation of nitrogen foam flooding in QHD32-6 Oilfield

Study on nitrogen foam anti-water-coning technology for conventional heavy oil reservoir;

A laboratory research on nitrogen foam adjustment of oil displacement in Bohai heavy oilfields;

Development and application of nitrogen foam injection system on offshore oilfield;

The new technique of injecting nitrogen-foam to enhance steam-thermal production result, which has such advantages as: wide gas source, cheap price, no corrosion, and unsophisticated process etc, represents the growing direction of current enhancing recovery factors.

In such circumstances,the nitrogen-foam profile control technology is developed in this paper.

Based on long core displacement experiment of constant temperature air foam, the effect research on enhancing oil recovery by air foam flooding after waterflooding was conducted.

In recent years, Study of Improved Oil Recovery through air foam flooding is more and more important.

The application and appraisement of the Nitrogen foam fluid well-washing technology in the workover of the SZ 36-1 oilfield;
