Analysis on exploration potential of buried hill in southern Niutuozhen uplift
Online published: 2011-04-20
The buried hill in southern Niutuozhen uplift of Jizhong Depression is characterized by little oil-bearing series and low degree of exploration. The oil sources, reservoir-seal assemblage, migration system and trap types of buried hill are studied. The result shows that the buried hill in southern Niutuozhen uplift has favorable hydrocarbon accumulation conditions, and developed two types of hydrocarbon accumulation models, including weathered crust of buried hill and inner buried hill, and different model has different characteristics of hydrocarbon migration and accumulation. It is believed that the buried hill in southern Niutuozhen uplift has favorable exploration potential. The buried hill monadnock trap in northern Xiong 11 well and the inner buried hill trap in Ba 28 well will be the next preferred exploration targets.
