对孤岛油田“九五” 以来的常规稠油开采和热采稠油进行了分析。常规稠油开采投入小,产出高,测算内部收益率高,经济效益好。热采稠油近年来经济效益好,内部收益率高于基准收益率,但由于固定资产投资累计值大,成本较高,测算静态指标较差。 The conventional heavy oil production and thermal recovery of heavy oil in Gudao Oilfield since the Ninth Five-Year Plan period have been analyzed. Conventional heavy oil extraction small investment, high output, estimated internal rate of return high, good economic returns. Thermal recovery of heavy oil in recent years, good economic returns, the internal rate of return higher than the benchmark rate of return, but due to the cumulative value of fixed assets investment, higher costs, poor measurement of static indicators.
