摘　　要：江陵凹陷万城潜山带是晚印支-早燕山期的挤压背景下形成的褶皱体系,经晚燕山-早喜山期的伸展背景下改造形成的潜山带。该潜山带具有较好的成藏条件,其成藏模式主要有潜山头成藏和潜山内幕成藏两种模式,综合研究认为万城潜山带是江陵凹陷拓展油气勘探新领域的重要有利区。The Wancheng buried-hill belt in Jiangling Sag was a fold system formed during the late Indosinian to early Yanshanian period subjected to the compression.It was transformed into a buried-hill belt through extension during the late Yanshanian to early Himalayan period.The belt has good accumulation conditions and mainly has two models of accumulation at the top of and inside the buried-hill belt.The finding believes that the Wancheng buried-hill belt is an important and favorable area for Jiangling Sag to expand its oil and gas exploration into new territories.
