利用网毯式成藏体系的研究思路,对准噶尔盆地白垩系油气成藏规律进行分析,研究网毯式成藏体系结构与油气成藏的关系.结果表明:准噶尔盆地油气成藏体系可划分为毯状仓储层、油源通道网层和油气聚集网层3个层次,其中仓储层以岩性地层油气藏为主,聚集网层以构造油气藏为主;总体上油气分布呈沿层发散,顺断汇聚的特点;分布稳定、物性好、厚度大的仓储层和沟通仓储的断裂及不整合是准噶尔盆地网毯式成藏体系结构中油气成藏的主控因素.

Using the fault-fracture mesh petroleum plays research method, the oil and gas reservoir forming rules in the Cretaceous of Junggar Basin were analyzed, and the relationship of fault-fracture mesh petroleum plays and oil-gas accumulation was researched. The results show that the petroleum accumulation system in Junggar Basin can be divided into three layers, including carpet type storage layer, meshwork layer of oil source passage and meshwork layer of oil and gas accumulation. In this configuration, lithologic stratigraphic oil and gas reservoir is the main reservoir type in storage layer, structural reservoir is the main reservoir type in meshwork layer of oil and gas accumulation. In generally, oil and gas distributed along the layer and accumulated and followed fault. The stable distribution, good physical properties, and a large thickness of the storage layer and fracture and unconformity which is connected with the storage layer are the main controlling factors for hydrocarbon accumulation in the configuration of fault-fracture mesh petroleum plays in Junggar Basin.
