摘要

In China, the heavy oil resources concentrates in 12 basins with about 70 oil reservoirs. The most important four heavy oil fields are Liaohe, Xinjiang, Shengli and Henan Oilfields, of which, Liaohe Oilfield and Xinjiang Oilfield belong to PetroChina. Liaohe Oilfield is the largest heavy oil production base of PetroChina. By the end of 2006, measured OOIP of heavy oil in Liaohe Oilfield was 1.05 billion tons, of which developed place in volume was 840 million tons and undeveloped place in volume was 210 million tons. In 2006, the heavy oil output was 7.645 million tons in Liaohe Oilfield, of which the annual production volume from cyclic steam stimulation (CSS) was 6.65 million tons (87.0%) and the production volume from steam flooding and SAGD was 175,000 tons, volume from cold production was 820,000 tons(Fig.1).
