摘要

摘要: 断陷盆地内稠油油藏与浅层气藏存在伴生关系，超过50%的浅层气藏来自于稠油的生物降解过程，但对从稠油油藏到浅层气藏的运移过程研究较少。通过对稠油油藏到浅层气藏输导类型、分布规律及输导要素的解剖，建立了2种输导模式，明确了运移成藏规律。断陷盆地内发育侧向和垂向2种类型的输导模式。侧向型主要发育在盆缘高凸起带，浅层气藏分布于稠油油藏的侧上方，输导过程以侧向运移为主，垂向主要受断层沟通，同时也以扩散方式直接穿越盖层垂向运移；垂向型主要发育在盆内洼陷带和低凸起带，浅层气藏分布于稠油油藏的正上方，输导过程以断层沟通的垂向运移为主。

Abstract: Heavy oil and gas have an association in a shallow fault basin reservoir. More than 50% of shallow gas reservoirs came from the biodegradation of heavy oil. However, there is little research on the migration process from the heavy oil reservoir to the shallow gas reservoir. Through the study of the carrier system type, distribution and elements of heavy oil and shallow gas reservoirs, two models were established, and the migration controls were clarified. There are two carrier system types: lateral and vertical. Lateral migration mainly developed in the high convex belt of the basin, and the shallow gas reservoir was distributed over the side of the heavy oil reservoir. The transmission process was dominated by lateral migration. Vertical migration also took place through diffusion along faults. Vertical migration mainly developed in the depression and low convection zone, and the shallow gas reservoir was located directly above the heavy oil reservoir. The transport process is dominated by vertical migration through faults.
