介绍了研究区泥丘的分布特征,即群状分布特征,泥丘上拱层位不一,高处可达东营组顶部。论述了泥丘的形成机制,认为泥丘的形成和源岩的生排烃有直接关系。讨论了研究区泥丘的形成时间,指出,由于泥丘的形成导致在泥丘周围形成一系列油气藏,其中有在泥丘上拱形成的背斜油气藏,有泥丘侧向封堵形成的油气藏,在泥丘内部的薄砂层中,还发现有岩性油气藏。
The distribution characteristics of the mound in the study area are introduced, that is, the distribution characteristics of the group of mounds. The layers of the arch on the mound are different from one another, and the top can reach the top of the Dongying Formation. The formation mechanism of mound is discussed. It is considered that the formation of mound is directly related to the hydrocarbon generation and expulsion of source rocks. The time of formation of mound in the study area is discussed. It is pointed out that a series of oil and gas reservoirs are formed around the mound due to the formation of mound. Among them, there are anticlinal reservoirs arched into mounds and lateral sealing of mud mound Oil and gas reservoirs, also found in the thin sand layer inside the mound, lithologic reservoirs.
