摘要
According to oil-gas play theory, the characteristics of oil-gas play and oil accumulation zone were studied of Wu-Xia fault belt, the northwestern margin in Junggar Basin. The results show that the oil-gas play can be divided into two types of oil play (above-source oil play and inner-source oil play) in Wu-Xia fault belt. The key factors of the oil-gas accumulation are the development of structural trap and oil-source fault. Under the remaining pressure, oil migrates upward along oil-source fault and migrates laterally along unconformity surface and sand-body which provides adequate oil for hydrocarbon accumulation.
