这篇论文的目的是有关第二等的石油移植考察竞争的主要的点，到在沉积的盆讨论性质和石油迁居小径的位置的主要控制，并且回答为大油/气体的形成说明优先的石油迁居小径的重要性离开生产厨房。在在异构的搬运人床上控制石油迁居小径的位置在驱动力(快活) 和制止的力量(主要渗透对比控制的毛状的压力) 之间有竞争。在大规模，有在在异构的搬运人床上控制石油迁居小径的位置决定结构的形态学或渗透对比的相对重要性的搬运人床的剧降的一个批评角度。Maximum-driving-force-controlled 迁居小径比批评剧降和石油迁居小径的位置主要被封上的表面的形态学控制的与大的剧降的一个角度发生在搬运人床上。Minimum-restraining-force-determined 迁居小径与比渗透对比将对石油迁居小径的位置施加更重要的影响的批评角度小的剧降的一个角度发生在搬运人床上。优先的石油迁居小径(PPMP ) ，定义为搬运人床的很限制的部分从生产厨房的一个大区域集中或专注石油，在沉积的盆决定油和气体的分发。集中石油从生产厨房的一个大区域发源进限制隧道似乎不仅为处于静水力学的条件的远程的石油移植，而且为大油或煤气的域的形成必要。因为它的三维的行为，区域可以错过石油移植，并且二维的移植建模可能在在某些情形预言石油出现是似是而非的。

英文摘要：

The aim of this paper is to review the major points of contention concerning secondary petroleum migration, to discuss the nature and primary controls of the positions of petroleum migration pathways in sedimentary basins, and to illustrate the importance of preferential petroleum migration pathways for the formation of large oil/gas fields away from generative kitchens. There is competition between the driving force （buoyancy） and the restraining force （capillary pressure controlled largely by permeability contrast） in controlling the positions of petroleum migration pathways in heterogeneous carrier beds. At a large scale, there is a critical angle of dip of the carrier beds which determines the relative importance of structural morphology or permeability contrasts in controlling the positions of petroleum migration pathways in heterogeneous carrier beds. Maximum-driving-force-controlled migration pathways occur in carrier beds with an angle of dip greater than the critical dip and the positions of petroleum migration pathways are controlled mainly by the morphology of the sealing surfaces. Minimum-restraining-force-determined migration pathways occur in carrier beds with an angle of dip smaller than the critical angle where permeability contrasts would exert a more important influence on the positions of petroleum migration pathways. Preferential petroleum migration pathways （PPMP）, defined as very restricted portions of carrier-beds that focus or concentrate petroleum from a large area of the generative kitchen, determine the distribution of oil and gas in sedimentary basins. The focusing of petroleum originating from a large area of the generative kitchens into restricted channels seems to be essential not only for long-range petroleum migration in hydrostatic conditions, but also for the formation of large oil or gas fields. Regions may miss out on petroleum migration because of its three-dimensional behavior, and two-dimensional migration modeling may be misleading in predicting petroleum occur
