| 摘 要： | 通过对泌阳凹陷油气成藏过程的系统研究,发现在差异抬升过程中,深凹源岩区抬升幅度小,凹陷四周圈闭发育区抬升幅度大,差异抬升运动导致源岩和圈闭之间的势能差急剧增大,从而促使油气大规模沿砂体向圈闭充注,这一过程类似于水泵抽水的过程,据此,文中提出了油气泵吸作用和油气差异泵吸作用的概念及机理,并以泌阳凹陷为例讨论了油气差异泵吸作用的形成条件、主要影响因素及油气差异泵吸作用对油气差异分布的控制作用。研究表明:影响油气差异泵吸作用的因素主要有势能梯度、通道质量和泵源配置及油气运移距离;泌阳凹陷油气分布总体上受成藏运聚系统的控制,在各运聚系统内油气分布受油气差异泵吸作用的控制,其中势能梯度、泵源配置及油气运移距离是影响油气差异分布的主要因素,而在每一个大泵(复合泵)内部,通道质量差异是影响油气差异分布的主要因素。 |

| Abstract: | In the systematic analysis of the process of petroleum accumulation in Biyang depression, it has been found that source rock distributed in the centre of the depression was uplifted in a small scale, however, traps distributed around the depression was uplifted in a larger scale in the course of differential uplifting tectonic movement. The differential uplift had resulted in that the potential energy difference between source rock and trap increases rapidly, which impelled petroleum to charge the sand body in a large scale, the course is very similar to that of pumping water. On the basis of which the concept and mechanism of petroleum pumping function and petroleum differential pumping function are put forward. The forming conditions, the influential factors of petroleum differential pumping function and how petroleum different distribution is controlled by petroleum differential pumping function in Biyang depression are discussed in the present paper. The results show that the main influential factors of petroleum differential pumping function are the difference of the potential energy gradients, the quality of pathway, and the distance between pump and source rock; the petroleum distribution was totally controlled by the petroleum migrating and accumulating systems, however, in each petroleum migrating and accumulating system petroleum distribution was controlled by petroleum differential pumping function, and petroleum different distribution was mainly controlled by the difference of the potential energy gradients and the different distance between the pump and the source rock; but in a large pump(composed of many single pumps) oil different distribution was controlled mainly by the difference of the quality of pathway. |
