Abstract: In 2002, Xinjiang Oilfield Company will reach bright target of oil production of 1000x104t, which is the historical breakthrough being strived for by Xinjiang's oil men of a few generations. Junggar basin has abundant foundations in hydrocarbon resources for stabilizing a ten million tons of annual oil production and realizing even higher yield; the valuable experiences from exploitation of complex oil and gas fields accumulated by the generations of oil men are also technically guarantees for them. For different types of hydrocarbon reservoirs, different stable production measurements should be adopted based on different development stages and principal issues. For instance, conglomerate reservoir should be classified into one, two or three types, and allowing implementation of chemical flooding as early as possible (e.g, CO₂ flooding, N₂ flooding and steam injection thermal flooding). After these tests, conversion into tertiary oil recovery would be made in order to realize stable production. The medium and low permeability sandstone reservoirs newly put into production should be managed and studied at the early stage; the heavy oil reservoirs should be converted into steam flooding as early as possible,followed by performing regulation and control of steam drive for maintaining stable production.
