固体沥青--反演油气成藏及改造过程的重要标志

Solid Bitumen—An Important Sign of Inverting the Process of Hydrocarbon Accumulation and Reconstruction

我国南方高演化碳酸岩地区普遍发育各种成因类型的固体沥青,固体沥青作为石油与天然气的伴生产物,记录了油藏从形成到被改造、破坏过程中的重要信息,在油气勘探的各个方面起着重要作用。沥青反射率可作为成熟度指标,固体沥青可指示油气的生成、运移,可作为气—源对比的中间桥梁,固体沥青自身可作为好的再生气源,并可用于古油藏储量规模恢复、油裂解气的资源量评价。深化固体沥青的研究,对海相高演化碳酸岩地区的天然气勘探有着重要的意义。

Solid bitumen of different genetic types is ubiquitous in the marine carbonate rock region with high maturity in south China.As the accompanying products of oil and gas,solid bitumen records important information of the accumulation,alteration and destruction process of reservoirs.Solid bitumen plays an important role in different aspects of the oil and gas exploration.Reflectance of bitumen is an index of the maturity.Solid bitumen can indicate the generation and migration of hydrocarbons,and it is a link ...
