高温防窜体系辅助蒸汽驱过程中应交替注入多个凝胶和氮气泡沫段塞，之后再注

In the process of assisting steam flooding with high temperature channeling prevention system, multiple gel and nitrogen foam slugs should be injected alternately, and then steam should be injected, and gel slugs should be injected first when injecting gel and nitrogen foam slugs.

High temperature anti channeling system should be replaced by multiple gelatin and nitrogen foam slugs in the process of auxiliary steam flooding, then steam is injected, and gel slugs should first be injected into gel and nitrogen foam slugs.

During steam flooding assisted by high temperature channeling prevention system, several gel and nitrogen foam slugs should be injected alternately, and then steam should be injected, and gel slugs should be injected first when gel and nitrogen foam slugs are injected.
