准噶尔盆地玛湖凹陷东斜坡深层成藏领域研究
Petroleum Accumulation Field in the Deep Strata of the Eastern Slope Area of the Mahu Sag,Junggar Basin
摘要
Abstract
In order to deepen the hydrocarbon exploration in the slope area of the Mahu Sag,northwestern Junggar Basin, and to provide a reference for studies with similar geological settings worldwide,we investigated the field of hydrocarbon accumulation and exploration in the deep strata of the eastern slope area. This was conducted based on analyzing accumulation features and conditions. Results show that the deep strata surrounding the Permian-Triassic unconformity is a key target of exploration in the studied area. In the target Permian and Triassic reservoirs,the oil is light in nature and they have good preserving conditions,favorable facies and relatively good-quality reservoir. Thus,high production may be likely,especially in the sub-facies of fan delta front. Combined with analyses of sedimentary and seismic facies and an integration/comparison of wells and seismic data,we investigated the spatial distribution of favorable facies and the dominant trap types. Results show that the favorable exploration area is large and the lithologic and stratigraphic trap is widely developed. Considering the low exploration level currently,the exploration prospect is wide and large. This likely provides a new exploration field and,thus, deserves to be strengthened in the future exploration.关键词
