近年来,贝尔凹陷苏德尔特潜山油藏的发现揭开了该地区潜山勘探的帷幕,在解剖苏德尔特潜山成藏条件的基础上,分析凹陷内其它地区的潜山成藏条件以期有所突破尤为重要。通过对贝中次凹潜山烃源岩、储层、运移等成藏条件的分析,结合试油资料和油气显示情况,认为构造背景、油气输导体系和储层发育程度是贝中次凹潜山油气成藏的主控因素。这对指导贝中地区和具有相似构造背景的潜山勘探具有重要的意义。
In recent years, the discovery of the buried hill reservoir in Suerdeerter of Beier sag has opened the curtain of buried hill exploration in this area. Based on the analysis of the accumulation conditions of Suderte buried hill, the conditions for buried hill formation in other areas In order to make a breakthrough is particularly important. Based on the analysis of hydrocarbon accumulation conditions such as hydrocarbon source rocks, reservoirs and migration in the Beizhong sub-buried hill, combined with the test oil data and the oil and gas conditions, it is considered that the tectonic setting, oil and gas transport system and the degree of reservoir development are the second Main controlling factors of hydrocarbon accumulation in concave buried hill. This is of great significance for guiding the exploration of buried hills in the Beizhong area and similar tectonic settings.
