Abstract
Following the thick oil development of Lean oilfield enters into later period,such problems as gas channeling,steam overlaying and side water invasion cause the uneven production of the reservoir;fire flooding test was conducted to solve this problem.Laboratory tests were conducted to select and evaluate the suitable tracers,and determine the specific dosage;sampling schedule was also made.Dynamic monitoring of the leading edge of fire flooding was conducted by using the gas tracer,temperature controlled tracer and isotopic tracer,etc.,which provided accurate and timely dynamic data for the test,and can also be used for reference for heating recovery of the same type of reservoir.
