富县地区中生界浅层气主要成藏地质因素研究

富县研究区是鄂尔多斯盆地油气勘探程度相对较低的一个地区。通过对研究区浅层气烃源条件、储层特征、盖层、圈闭等主要成藏地质因素进行分析，认为研究区处于生烃中心，油源充足；储集空间发育；气藏类型主要为岩性、构造一岩性圈闭；受静压力、动压力、水动力作用、扩散作用、毛细管作用等的影响，研究区中生界浅层气运聚的主要通道为古侵蚀面、砂体、断层或微裂缝。

Main Reservoir- forming Geological Factors of Mesozoic Shallow Gas in The Fuxian Region

Fuxian county is an area where the degree of exploration for oil and gas in the Ordos Basin is relatively low.In this paper,through analysis of the main reservoir-forming factors in Fuxian area,it is believed that the research area lies in center of hydrocarbon generation,which has abundant oil sources,abundant reservoir space,and the type of gas reservoir mainly are lithological trap and tectonic-lithologic trap.For the effects of static pressure,hydrodynamic pressure,hydrodynamic disturbance,diffusion and...
