本文通过物理模拟实验研究了含水的凸镜状砂体聚油过程，认识了静水条件下毛细管力和排烃压力的综合作用．造成砂体油水交替聚油成藏。其中“源岩”内凸镜状砂体聚油作用最快，而有缝隙沟通“源岩”外泥岩中凸镜状砂体聚油作用则较慢，其中，“源岩”在上者又比“源岩”在下者慢。
In this paper, the physical simulation experiment was carried out to study the oil-buildup process of water-bearing convex lens sand bodies, and to understand the combined effect of capillary pressure and hydrocarbon expulsion pressure under the condition of still water. Resulting in sand oil and water alternately poly oil accumulation. Among them, the “source rock” convex lens sand body has the fastest oil gathering effect, while the gap-communicating “source rock” convex mirror sand body in the outer mudstone has a slower oil-gathering effect. The “source rock” Than the “source rock” in the next slow.
