Examples
- This paper also summarized a way how to do the early reservoir description in the preparatory reconnaissance stage . in the paper author provided a detailed study of sedimentary facies , reservoir , the forming conditions of hydrocarbon pool , structure feature and reservoir prediction about the sidaogou structure , and point out the primary reason for producing a little oil and gas in the sidaogou structure , and gave the main direction for the future petroleum exploration in the hami depression
因此，本文系统地阐述了早期油藏描述的定义、意义和任务，建立了早期油藏描述较完整的研究思路和研究方法，并通过对吐哈盆地哈密坳陷四道沟构造低产油气藏的早期油藏描述具体研究工作，摸索和总结出一套如何将早期油藏描述技术应用于油气藏预探阶段的研究方法。 - The direction of migration was in east and northeast . ( 3 ) this paper introduced the balanced section into the early reservoir description in the sidaogou structure for the first time , and gave a new viewpoint that the sidaogou structure was a fault - bend fold formed by two step thrust fault . the structural stress direction came from the northeast of the hami depression
首次将平衡剖面技术引入了四道沟构造早期油藏描述的构造研究之中，并首次提出四道沟构造是?至少由两个阶梯状断层组成的后倾双重构造叠加的断层转折褶皱，构造应力方向应大致源于北东方向。 - ( 2 ) analysis for the forming conditions of hydrocarbon pool , structure and reservoir features shows that the sidaogou structure had two period of migration and accumulation of oil and gas . the first period of migration and accumulation came from the hydrocarbon formed in the source rock of the sanpu depression and formed the asphalt in the sandstone reservoir of triassic and jurassic in the well ha - 2 . the second period came from the hydrocarbon formed in the source rock of triassic round about the well ha - 2 and ha - 3 and formed the hydrocarbon pool in the sidaogou
这是对油藏描述技术和应用领域的完善与补充。通过对四道沟油气藏油气源和油气运移与聚集研究，首次提出四道沟构造存在两期油气运移与聚集，指出了油气生成与运移时期和主运移方向，以及各期油气对四道沟现今油气藏的贡献大小。
